Product Details

If the new Sinn 556 I RS (red seconds) looks familiar, you're not mistaken.  This watch is now a general release by Sinn, but for years was a WatchBuys special edition.

Our special edition was such a hit that Sinn decided to expand production and add the watch to its worldwide collection.

More Attitude

The Sinn 556 I RS has all of the great features of the bestselling Sinn 556 I, but our clients say the red seconds hand offers "a bit more attitude."

The red seconds hand gives the watch a sporty look and feel, while still providing stark contrast against the inky black dial.

The Sinn 556 Series offers a great mix of performance, durability and classic Sinn design.  For these reasons, they are among Sinn's bestselling watches of all time.

This version of the Sinn 556 RS is marked "I" for Indices only. 

Important features of this watch include:

  • Case made of satinized stainless steel
  • Sapphire crystal glass on both sides
  • Water resistant to 200 meters
  • Date display at 3
  • SuperLuminova on the hands and hours (glows green)
  • Inky black dial
  • Double antireflective coating
  • Premium Grade (highest) movement

This watch is fitted with a Sinn stainless steel H-Link bracelet.

WatchBuys is the official and authorized North American distributor and importer for Sinn watches.

When you purchase your new Sinn watch from WatchBuys, you'll not only get a finely engineered timepiece with excellent value for money, you'll also benefit from the WatchBuys Sinn Advantage.

WatchBuys Advantage #1

Because we are the official and authorized North American Sinn distributor and importer, your name and watch serial number will be automatically registered in our database for a Sinn manufacturer's limited warranty which we pass through.

This means that should your watch require service during the Sinn manufacturer's limited warranty period, service will be provided by Sinn in Germany when you return your watch to them. This Sinn manufacturer's limited warranty is transferable to subsequent owners as allowed by Sinn.

You are responsible for paying the shipping charges to Sinn, and all repairs that Sinn approves under its warranty are at no charge. Sinn will also pay the return shipping charges to the address you specify.

The Sinn manufacturer's limited warranty period is as follows:
  • Watches in the EZM Series: 3 years
  • Watches marked AR containing inert gas: 3 years
  • Watches in the DIAPAL Series: 5 years
  • All other Sinn models: 2 years

WatchBuys Advantage #2

As an added benefit to those who purchase Sinn watches from WatchBuys, you may choose to have your warranty repairs serviced through our US Sinn Authorized Service Center, RGM Watch Service located in Mount Joy, Pennsylvania. This added benefit saves our clients the time and effort of returning their watches to Germany for repair. This service is transferable to subsequent owners who purchase directly from the original registered owner.

Please note that you are responsible for paying shipping and insurance charges for sending your watch to RGM. Once they reach your watch in the service queue they will determine which repairs are covered under Sinn's warranty.

It is important to note that oil-filled quartz Sinn watches must be repaired in Germany (EZM 2, Hydro and UX series). If your watch meets one of these conditions and requires service under warranty, please click here for instructions on returning your watch to Sinn in Germany.

WatchBuys Advantage #3

Your watch will be repaired at no cost to you other than shipping charges to either Sinn or RGM during the warranty period. Sinn watches purchased through the "grey market" (non-authorized sources) may carry no warranty from Sinn. Sinn watches purchased through authorized overseas retailers are governed by the warranty policies of those dealers and/or Sinn, and typically must be sent to either the overseas dealer or Germany for repair.

WatchBuys Advantage #4

You'll be wearing your new Sinn watch soon after your order is placed since we stock Sinn watches and ship free using UPS Air. Plus, since we are located in the United States, there are no "hidden charges" for shipments to US residents as is the case with most overseas dealers. Such charges can add up to 15% to the cost of your new watch, and include credit card surcharges, foreign exchange credit card bank fees, import duties and taxes, and custom's broker charges.

WatchBuys Advantage #5

WatchBuys offers a comprehensive return policy with no restocking fees to US residents. Overseas dealers, including those involved in the grey market, typically don't offer a return policy, and if they do, returning a watch under the policy is both complicated and expensive due to import/export and custom's requirements. Restocking fees are also common and may range up to 15%.

Learn more about our return policies.

WatchBuys Advantage #6

WatchBuys is pleased to accept payments through PayPal, debit and credit cards. We charge no surcharges to use credit or debit cards, and because we are based in the United States your US card is charged in US dollars with no conversion or exchange rate fees.

We also accept payments from PayPal and charge no surcharges.

Please note that to pay by credit card, debit card or PayPal your account and/or card must be issued by US or Canadian financial institution and billed to a confirmed US or Canadian address.

WatchBuys Advantage #7

When you purchase your new Sinn watch from WatchBuys, you'll earn WatchPoint Rewards which accumulate and may be redeemed against future purchases.

Sinn watches feature a number of cutting edge technologies, many of which are unique to Sinn. Please note that not all Sinn watches, including the watch on this page, use all of these Sinn technologies.

Among the more notable Sinn technologies are:

Tegimented Hardened Cases

Many Sinn watches are fitted with Tegimented cases produced in-house by Sinn's case making affiliated company in Glashutte, Germany.

Standard steel used by most watch companies has a hardness of between 200 and 240 HV (Hardness Vickers is a common scale used to measure material hardness). The Tegiment process produces a hardness of at least 1,200 Vickers which is five times harder than standard steel (and on some Sinn models up to nine times harder than standard steel).

The Tegiment process is not a coating consisting of a foreign material; instead the steel itself that has been hardened using a special engineering process that creates a hardened barrier. The base material is a type of stainless steel also used for surgical implants, and the stainless steel resistance to corrosion is further improved by the Tegiment hardening process.

The primary advantages to a Tegimented case are extreme resistance to scratches and other case abrasions, as well as increased resistance to corrosion.

Please note that certain Sinn watches are fully Tegimented (case, bezel) while others are Tegimented only on the bezel. Use the links below to view both categories.

  • View Sinn watches with fully Tegimented cases.

  • View Sinn watches with Tegimented bezels only.

Dehumidification Technology

A number of Sinn models feature cases filled with inert gas. Sinn has found that filling the case with inert gas can help prevent the introduction of moisture and humidity to the case, as well as provide a more stable environment for the oils that lubricate the movement.

The proper care of any mechanical watch movement mandates that these oils maintain both their viscosity and lubrication properties.

  • View Sinn watches with dehumidification technology.

Copper Sulphate Capsules

A number Sinn models use one or more copper sulphate capsules to absorb humidity trapped inside the case. Over time these capsules will gradually turn dark blue indicating that humidity has been absorbed.

The primary benefit to these copper sulphate capsules is a more dry and stable environment for both the movement and the lubricating oils. Together with Sinn's inert gas treatment these capsules form the basis of Sinn's Dry Hold Technology.

This technology not only provides a more stable environment for the movement, but also prevents fogging of the crystal when going from hot to cold environments or from humid to non-humid conditions (such air conditioned buildings).

  • View Sinn watches with copper sulphate capsules.

Extreme Antimagnetic Protection

Magnetism can cause dramatic swings in the timekeeping of a mechanical watch movement. People are often exposed to magnetic fields without even being aware - frequent high altitude flying, metal detectors, audio and video equipment, medical equipment and computer equipment can all cause problems with magnetism.

Many Sinn watches offer extreme protection against magnetism up to 80,000 A/m. Sinn achieves these results using a number of different technologies, including special case and case back construction, soft iron components in the case and protective rings surrounding the movement.

  • View Sinn watches with extreme antimagnetic protection.

DIAPAL Oil Free Escapement

Sinn caused quite a stir when they first released their DIAPAL technology. Beginning in 1995, Sinn began work to create an oil free escapement. With any mechanical watch movement, the aging of oil, especially in the escapement can create long term problems for that movement. Additionally, as movement oil ages, required service intervals become more frequent.

Sinn's early analysis to this problem provided a quick solution (at least in theory) - if you don't use oil, it can't age. The process began by exchanging the ruby escapements for diamonds (the word "DIAPAL" derives from the German name for diamond escapements) in order to achieve the desired effect. The designation stuck, even though today Sinn works with solutions taken from advanced nanotechnology rather than diamonds.

The result is a movement that proves so reliable that Sinn offers an unprecedented five year warranty on their DIAPAL watches.

  • View Sinn watches featuring the DIAPAL oil free escapement.

Hydro Oil Filled Technology

Sinn has developed a technology termed "Hydro" in which the entire watch case is filled with oil. Watches using this technology are based on quartz rather than mechanical movements.

By using this type of movement, Sinn is able to fill the watch with oil, which has the joint affect of greatly enhancing the readability of the dial and time from any angle (including under water), and increasing the water resistance of the watch even at great depths.

  • View Sinn watches with Hydro Oil Filled technology.

Submarine Steel

Sinn has created a line of watches featuring cases made from German submarine steel (the U Series). The steel was procured by Sinn from a steel supplier to Emden GmbH, one of Germany's North Sea shipbuilding yards who construct submarines from the very same steel.

Because of the special steel used from the submarine steelmanufacturer, the case resists the effects of exposure to salt waterand salt water environments.

These cases are produced in-house by Sinn's case making affiliated company in Glashutte, Germany.

This special steel is also amagnetic which means that is does not have magnetic properties and cannot itself become magnetized. The watch movement itself is protected from magnetic fields up to 4,800 A/m.

  • View Sinn watches built from German submarine steel.

EZM Mission Timers

Sinn is a partner for manufacturing watches for the German Special Forces, including SWAT, Customs, FBI, helicopter police, GSG9 and other units.

Beginning with the now highly collectible (and valuable) Sinn EZM 1, Sinn has grown this collection to some of the most durable and highly functional watches made and they remain among the most popular in the collection.

The Perfect Do-Anything Watch

"The Perfect Do-Anything Watch"

Verified Watch Owner Comments: Very impressed with the quality and looks of this watch. The 38.5mm case is the perfect size for my 6.75 wrist, and the watch is extremely legible under a wide variety of lighting conditions. It truly is a do-anything watch, wearable with shorts and a T-shirt, or a sport coat and tie.

Impressed with the great customer service and attention to detail of the WatchBuys staff, too.

Perfect Strap Monster

"Perfect Strap Monster"

Verified Watch Owner Comments: The perfect watch to switch straps. Has an incredible lume. Keeps great time. I bought it with the H link bracelet and purchased 7 different NATO straps. watch is simple enough to wear with anything and classy enough to dress is up with a leather strap and wear it formally.

I also have a few rolexes. But I wear this watch almost more frequently as a daily piece that I dont feel bad to beat up.

Better than I imagined.

"Better than I imagined."

Verified Watch Owner Comments: I have been eying the 556 for a few years going back and forth the indices and numerical version. Decided on the indices because of the intensity on the black dial. The watch is beautiful and better than the online pictures.

I went with the red second's hand because I love the way the red pops with the ink-black dial. I didn't expect much from the bracelet but it too is a gem. I am very pleased with the watch and the service from Watchbuys.

Sinn 556 I RS - Perfect Buy

"Sinn 556 I RS - Perfect Buy"

Verified Watch Owner Comments: Exactly the watch I wanted, glad I caught a restock. The hex-cell screws make sizing the bracelet extremely easy, even for novices, compared to other typical watches. The red hand second is such a nice little touch.

Extremely quick delivery, and WatchBuys customer service called to confirm shipping details immediately. Top notch service for a top notch watch.

Versatile everyday watch with a pop

"Versatile everyday watch with a pop"

Verified Watch Owner Comments: I chose the Sinn 556 I RS because of its versatility and everyday wear.The ink black dial, white indices and red second make the watch pop with an attitude. Although I purchased with the H bracelet (I recommend) I am looking forward to swapping out straps with this strap magnet.

Dressing up or wearing jeans the watch gives versatility in wearing choices. Wearing a Sinn in itself says a lot about your choice in watches...You know value, quality and style.

The purchase process with Watchbuys was very positive experience with their knowledge, professionalism and expertise.

100% Satisfied

Solid everyday watch

Verified Watch Owner Comments: Absolutely love this watch. The gloss black dial is a thing of beauty, I can't stop looking at it. The red seconds hand is a real eye-catcher too.

The Best!

"The Best!"

Verified Watch Owner Comments: I've been considering this watch for years, and I'm so glad I finally made the purchase. I haven't taken it off since I received it almost two weeks ago.

Verified Watch Owner Comments: I really love this 556i with the red minute hand. The glossy black background really makes this watch pop on the wrist.

This is my 2nd Sinn watch and I've consistently been impressed by the quality of the watches and the service of watchbuys. If I were to suggest something - get the h link bracelet. It's a looker on the wrist. Now I want more Sinn watches...

Verified Watch Owner Comments: I did a ton of research online prior to purchasing this watch, which is my first. I received just what I was expecting in the way of form, function, fit and finish.

The Sinn 556 is perfect for my everyday watch. It's proven to be tough enough and beautiful at the same time.

What I wasn't expecting was the personal attention I received from Watchbuys after I placed my order. I really appreciate the phone calls, they're a welcome touch these days. Thank you Watchbuys for making my first watch purchase a great experience. When I'm in the market again, Watchbuys will definitely be at the top of my list.

Good looking watch

"Good looking watch"

Verified Watch Owner Comments: Sinn 556 l RS on H link bracelet is well made , easy to adjust to the wrist thanks to Sinn and WATCHBUYS for the tools that are included and like the review title says good looking watch.

Thank you WATCHBUYS, Service is A-1

Elegant and rugged.

"Elegant and rugged."

Verified Watch Owner Comments: As soon as I received it, the 556I RS became my favorite watch. The versatility is unmatched. You can put it on any strap or bracelet and wear it for any occasion. The watch is very well built.

I get nothing but compliments while wearing it. I would highly recommend this watch. I’m not a 1 watch kind of guy, but this watch could fill that role if you are looking for one. Buy this watch!

Sinn 556 I RS

"Sinn 556 I RS"

Verified Watch Owner Comments: I am really pleased with this watch. It is just the right size for my medium wrist. It’s very legible, so I can see it without my reading glasses (well, I do struggle with the date a bit.,.). The included tools made it really easy to size the bracelet myself (the hex screws are a great idea).

The accuracy of the watch is so far superb. I’ve had it a couple of weeks and it is still within 5 seconds. I found that it runs a bit fast on my wrist, and a bit slow sitting crown up on my dresser so the two effects keep it right on.

Watchbuys was excellent to deal with. They called me to confirm the details of my order, and shipped it promptly. I think I had it in hand within 2-3 days. Overall, I am very happy with my purchase.

Sinn 556

"Sinn 556"

Verified Watch Owner Comments: A really great watch delivered swiftly. Wear this every day. So easy to read. Simple, elegant, functional and durable. Looking for my next Sinn.

Should have bought one sooner!

"Should have bought one sooner!"

Verified Watch Owner Comments: Beautiful and 100% practical. Super legible: the hands and indices really pop off the inky black dial. Brushed finish: if it picks up a scratch, I can dress it out with scotchbrite. Perfect size, great bracelet.

Running very well: less than +1spd. Great service from WatchBuys too!

First purchase at Watchbuys

"First purchase at Watchbuys"

Verified Watch Owner Comments: Everything about my experience with Watchbuys was first-rate. A very thorough and professional organization. Will definitely buy from them again when the need arises.

Fantastic Tool Watch for the $$

"Fantastic Tool Watch for the $$"

Verified Watch Owner Comments: Have long admired the simple and austere aesthetic of the Sinn 556 - don't know that you can get a better engineered tool watch for the price. My wife loves the way it looks on my wrist as well.

Would absolutely buy this watch again and it has become a part of the regular rotation.
