Product Details

Focused on Function

The Sinn 105 UTC Series is a collection of watches designed for wherever your adventures may lead.

While it may look like a pilot's watch, the versatile Sinn 105 St Sa UTC boasts a diverse range of functions. 

With a bead blasted case, a Tegimented 24 hour GMT bezel, a day/date display, second time zone complication, and 200 meters of water resistance, the Sinn 105 St Sa UTC packs a little bit of everything into a whole lot of watch.



Inspired by the Sinn 104

Since its introduction in 2013, the Sinn 104 Series has quickly become one of the best selling watches in the company's history.

When we released a special edition bead blasted Sinn 104, it was a major success.  Our clients were thrilled to have a more sporty alternative to the traditional polished Sinn 104 case, and the Sinn 105 UTC Series incorporates this same matte bead blasted finish.

A primary advantage to this matte case is increased resistance to scratches and other blemishes, which are much more visible on a highly polished case.

Watches in the Sinn 105 UTC Series also feature a DLC Tegimented bezel and a new dial design.



Sporty Design

Although this watch takes its cues from pilot's watches, its design and variety of functions make the Sinn 105 St Sa UTC extremely versatile.

The rounded, pill-shaped hour markers are highly legible and offer a stark contrast against the dial.  An orange, arrow-shaped UTC hand stands out against the black and white dial and gives the watch a sporty look.

The ratcheting bezel is of Sinn's design and will not snap off the case if hit due to its screwed bezel construction.  It is Tegimented with a DLC finish.  

By installing a 24 hour rotating bezel, Sinn provided this watch with a second method of tracking a second time zone in addition to the UTC hand.  With the UTC hand on local time, the bezel can be rotated in accordance with the second time zone being tracked without the need to reset the UTC hand.

The orange UTC hand may also be used to roughly determine cardinal directions when the sun's position is visible in the sky. If you’re located in the northern hemisphere, position the dial horizontally and turn the watch so that the main hour hand (ignoring daylight savings time) points toward the sun.

The 24-hour hand then points north.



Important features of this watch include:
  • Stainless steel matte case, bead blasted
  • Captive Tegimented bezel with DLC finish
  • Sapphire crystal on both sides
  • UTC complication with 24 hour hand
  • X1 SuperLuminova on the hands and hours (glows green)
  • Water resistant to 200 meters
  • Date display at 6
  • Low pressure resistant
This watch is fitted with a bead blasted Sinn H-Link steel bracelet with a locking clasp.

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 daily watch

"The perfect daily watch"

Verified Watch Owner Comments: I decided to purchase this Sinn 105 UTC to replace my previous daily watch which was a Hamilton Khaki that I had for over 15 years. Although 105 is a 41mm watch, it feels like a 40mm watch when you wear it. The bracelet was very easy to adjust and I have been wearing this watch every day since it arrived!

Every click, dial adjustments feel solid and well built. I appreciated the personal call from watchbuys to confirm my purchase and shipping methods to make sure everything was correct. Thank you!

Sinn excels

"Sinn excels"

Verified Watch Owner Comments: The Sinn 105 doesn't disappoint. The fit and finish are excellent. Even the crown threading is way better machined than my higher priced luxury watches. Very impressed.

Sinn 105 St Sa UTC on Bracelet

"Sinn 105 St Sa UTC on Bracelet"

Verified Watch Owner Comments: Love the watch. It took me a while to figure out that this style of German Tool Watch is my thing. Several Youtube video reviews helped. The mat black dial, bead blasted metal finish and simplified graphics are great. The Swiss movement keeps time to +3 seconds a day. One thing that can be improved - the bracelet clasp. I'm not the first one to point this out...come on German designers catch up.

What a beauty

"What a beauty"

Verified Watch Owner Comments: This watch was a gift for my father. Not only was it a last minute buy for the holidays but the Sinn 105 St UTC is virtually impossible to find anywhere. Watchbuys had it!

I made the order and called into Watchbuys to confirm the shipping address. I unfortunately dont remember the gentleman’s name who helped me but he was extremely helpful, personable, and professional. The entire process took no time at all and having ordered online (not something I usually do for a watch) the service made me feel completely at ease.

The watch showed up at the door the NEXT day. My father was shocked with the gift, it wears better than he thought. It is now his favorite watch and loves to show it off. Thank you Watchbuys for excellent customer service and inventory! Will be purchasing again.

Verified Watch Owner Comments: I own a 556, 856 and 356. The 105 is my favorite Sinn. Incredible watch. Incredible service from watch buys. A++

Sinn 105 UTC, a great GMT watch

"Sinn 105 UTC, a great GMT watch"

Verified Watch Owner Comments: I am really happy with this purchase. I had searched for a gmt watch that can do the following: 40mm in size, water proof of at least 100m, bi-directional rotating bezel, 12mm in thickness, GMT/UTC function. Sinn 105 UTC met all my criteria, a great watch at a great price.

The staff at Watchbuys are great and extremely helpful. A great place to buy German watches.

My second Sinn

"My second Sinn"

Verified Watch Owner Comments: I've been looking for a new watch and Omega has been on my radar for some time. Although the quality of a speedmaster is undeniable and so it's good looks, Sinn offers something a little different. Watches with a purpose. Having owned a 156 for close to 30 years, I think of it as a tool, a needed piece of equipment and also a watch that has a presence. This is what I found in my new 105 UTC. For I know I'll have it on my wrist for the next 30 years with my 156. The 105 looks good on my wrist and at 41' it's a perfect size. The dial and bezel are well balanced and a good fit for a small wrist. I find the glass back a bit superfluous but I like the no nonsense easy read of the dial. UTC arrow is all there and gives the watch a little bling. The bezel is firm and I like the tough finish as opposed to the bezel on my 156 which has worn out over time. I also find it easy to read a different time zone just by moving the bezel. Watchbuy made it easy to get and I thank them for that. I a... - more details

Good Quality and Value

"Good Quality and Value"

Verified Watch Owner Comments: This is my second watch purchase from Watchbuys. I bought the 105 UTC simply because I liked how it looked. It appears to be slightly better quality than my 104, which has served me well for the last six years and, which I still use.

I don't like a lot of bells and whistles nor do I need a stop watch on my wrist. The UTC hand is a nice feature for travel, though.
