Product Details

This is is a special edition of the Sinn 556 I - you'll notice the addition of a red seconds hand.

We periodically work with Sinn to produce this special edition for those who prefer a more sporty look to the Sinn 556 I.

The Sinn 556 I Red Special Edition has all of the great features that have made the Sinn 556 I among our best selling Sinn watches, but with the red seconds hand offers a bit "more attitude".

The Sinn 556 I Red Special Edition features a satinized case at 38.5 mm.  This finish results in a slightly more polished look while at the same time retaining some characteristics of a matte finish.

In addition, the dial features indices ("I") rather than Arabic numerals for a very clean layout.

Other features include:
  • Case in 316L surgical stainless steel
  • Sapphire crystals on both sides of the watch
  • Double coated anti-reflective covering
  • Dual seal crown lock to improve water resistance
  • Dial features a black lacquer finish

Water resistant to 200 meters.

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, 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 service center, RGM Watch Service located in Mount Joy, Pennsylvania. This added service saves our clients the time and effort of returning their watches to Germany for repair. This benefit 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 contact us and we'll provide instructions for shipping the 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 FedEx 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 556 I Red Special Edition

"Sinn 556 I Red Special Edition"

Verified Owner Comments: The Sinn 556i Red Special Edition is a beautiful watch with a utilitarian tool watch vibe. Dresser than most tool or pilot inspired watches. At 38.5 mm it is great for most wrist sizes. To me it presents a bit larger than my other 38 mm watches. It is a very solid Swiss watch movement in a precision German watch. The presentation of the movement is very upscale and enjoyable to view. The crown and case are precision machined and have that feel. Sapphire front and back great, UV coating on the outside may scratch later. Impressive 200 m water resistance in a pilot watch will insure that over the years it will stay resistant. I love the look of the regular 556i on the bracelet, but the red second hand makes the special edition look sportier. The face is glossy inky black, contrasted by the white indices. This and the more shiny bracelet make it look more dressy and eye-catching. A very different look than the watches that are tegimented and have a matte black face, those look more to... - more details

Perfect candidate for a one watch collection

"Perfect candidate for a one watch collection"

Verified Owner Comments: I was looking for a solid mechanical watch that was a serious commitment to good horology without breaking the bank. Last year, I briefly got to try both the regular 556i and the Sinn 104 for an extended period of a month or so, but felt something wasn't quite right with either. I loved both watches but thought at times the 556i was too monochrome (some may like that), and the 104 not dressy enough (but it comes pretty close) due to the bezel.

This special edition 556i with the red hand did just the trick for me, adding just the right bit of subtle color to the monochrome dial. There is nothing out there quite like the Sinn 556i in looks, features or execution at this price point, and you'll never regret owning one.

Can't say enough about the great service from Watchbuys - cheers Matt for patiently answering all my questions and Kevin for calling after I made the purchase to add a personal touch!

"Patek Aquanaut's Stunt Double:)("

Verified Owner Comments: Great watch. I have a 1992 Patek Aquanaut, and this Sinn is its 'stunt-double'. Similar feel, but better for daily wear.

A tough-guy, to keep the star looking good.

Understated elegance

"Understated elegance"

Verified Owner Comments: The Sinn 556i is awfully elegant, with its clean design and simple functionality. Understated is the point here. Plus its medium size is a great antidote to all the dinner plates folks wear on their wrists these days. I simply love mine with the red second hand that give it a small but distinct accent.

And WatchBuys did a fine job of shipping it promptly and painlessly. Thank you.

Verified Owner Comments: Awesome watch! Wish it came on the bracelet though. The leather band is a bit stiff and really digs in after the day is done.

Built to last, attainable luxury

"Built to last, attainable luxury"

Verified Owner Comments: Truly a sight to behold. Love this watch, and its excellent for the price point. Winding feels very nice compared to my previous watch. Got it on a bracelet and it doesn't attract/hold onto as much dirty as many other bracelets I've had. Was worried about the AR Coating on the crystal getting scratches, and while it's so far been just fine, the Coating does show/attract smudges so I'm having to wipe down the crystal with a microfiber cloth on a daily basis, but it's no big deal.

Would recommend this watch to anyone looking for a minimalist, simple, yet elegant design on a truly attainable luxury watch.

Simple Elegance or Elegantly Simple

"Simple Elegance or Elegantly Simple"

Verified Owner Comments: One doesn’t think of a pilot or tool watch as being elegant. However, this Sinn 556i is a classy, very attractive pilot watch that I enjoy not only wearing but also just looking at. From the piano-black dial, highly contrasted white hands and indices, and red accented seconds hand, this IS an elegant tool watch.

I’m now in the process of strapping it up – maybe a black leather strap with some red piping, or a dark brown leather strap – I think this particular piece is a strap monster. Many straps will look great on it. Plus the quality is readily apparent. I appreciate the 200m water resist and the top grade ETA 2824-2. I'm getting -2 secs/day accuracy on my timegrapher.

And the customer service from Watchbuys was excellent. Both pre-sales support where all my questions were answered, to post sales where I received a follow-up call to ensure I was happy with the purchase. I’m very pleased with this purchase from Watchbuys.



Verified Owner Comments: This is my second Sinn - the other a U1. This 556 holds it's own against watches that cost a lot more. While a simple watch, it's the details that really stand out. Incredibly legible, comfortable, 200m water resistance, crown guards, excellent proportions, and looks good on many different straps.

The finishing on the case is first rate, and that red second hand definitely pops, adding sportiness compared to the normal version. Altogether, just a superb package from Sinn at this price point.

Verified Owner Comments: This is my third purchase from Watchbuys.

I've consistently found the service to be outstanding, Rob's and Matt's response to questions and phone calls quick, thorough and overall customer service about the best anywhere. Beyond that, the Sinn watches I've purchased are really terrific.

Very solid build quality, robust, accurate and always promptly shipped from Watchbuys in perfect condition. These folks do a really great job overall. Thanks for your always good service and products.

Terrific Watch!

"Terrific Watch!"

Verified Owner Comments: The Sinn 556i Red is an awesome watch. Extremely well made, a perfect precision minimalist watch. It is my my everyday watch, love it!

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).

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.

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.

  • View Sinn watches in the EZM Series.

TESTAF Certified Pilot's Watches

Lothar Schmidt, Sinn's CEO and owner had long been disturbed by a lack of technical standards for defining a "pilot's watch". As an engineer, Mr. Schmidt was fluent in standards for diver's watches, anti-magnetic watches and the many other technological standards used to manufacture watches.

A widely used reference for standards is DIN, or the Deutsches Institut fr Normung (German Institute for Standardization). Oddly, he discovered there were no DIN standards to cover pilot's watches where such standards existed for example for diver's watches.

The new "Technical Standard for Pilot's Watches" (TESTAF) was developed by the Aachen University of Applied Sciences and establishes the suitability for professional use as a pilot's watch.
