Product Details

The Sinn 144 St Sa Series is one of the earliest designs from the brand, and even today remains highly popular.

This three register chronograph features both a day and date display, and we love the contrast between the red hands and matte black dial.

Another point that Sinn got right on this watch is the case and bracelet finish.  Made from 316L stainless steel, the finish is highly bead blasted with no shiny surfaces.  The watch uses a screw down crown and is rated at 200 meters for water resistance.

Functions include hours, minutes, subsidiary seconds, day, date, pulsometer and tachymeter scales, and complete chronograph functions.

This watch is fitted with a Sinn stainless steel H-Link bracelet with locking clasp (not quick adjust).

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.

My new daily driver!

"My new daily driver!"

Verified Watch Owner Comments: I recently acquired the Sinn 144 St Sa from WatchBuys, and it has surpassed all expectations. The watch's design strikes a perfect balance classic and contemporary aesthetics, reminiscent of the Porsche Design Orfina, and it looks even better in person.

The distinctive shaped case wears exceptionally well, along with the easy to read chrono and great water resistance, makes it a perfect everyday watch. Its quickly becoming my daily driver.

WatchBuys provided excellent customer service, ensuring a smooth buying experience, and the timely delivery made the entire process even more satisfying. The Sinn 144 St Sa is an awesome timepiece that combines elegance, durability, and precision, making it a valuable addition to any watch collection.

"144 st sa"

Verified Watch Owner Comments: My first watch arrived with a defect unfortunately. I contacted watchbuys and had an immediate response with a paid return label and then a replacement sent upon delivery. No hassle, no questions asked. Top tier service, as expected.

The watch itself is excellent. Indices are crisp and legible, lume is good, Chrono pushers are positive and firm. The Chrono hands are more orange than red to my eye, which is what I had hoped for. Accuracy is so far holding at +1.9/day. We'll see how it settles as it wears in. Buy with absolute confidence.



Verified Watch Owner Comments: Excellent experience with WatchBuys, as always.

The 144 is a modern classic with a workhorse movement and very cool vintage styling. The angled tachy scale and orange hands give the dial a ton of character and depth that doesn’t always come across in photos.

Quality and accuracy is outstanding.

Solid Watch, Great Legibility

"Solid Watch, Great Legibility"

Verified Watch Owner Comments: I've had this for almost two weeks now, and it's rarely left my wrist. The construction and finish are impeccable. This watch is extremely legible, with excellent contrast the main hands and markers and the deep black matte dial.

I particularly like the color of the chronograph hands - they seem brighter in person than they appear in the stock photos. A nice pop of color on a serious watch. Timekeeping has also been great, gaining about five seconds a day, and I expect that will improve as everything settles in.

Overall, it's a great watch at a really good price point. And a bonus is the excellent customer support from Watch Buys, with friendly service when ordered and timely shipping confirmation. Can't ask for more!

Verified Watch Owner Comments: As always, easy ordering process and quick shipping from WacthBuys.

The 144 is really great- the dial is well structured and the pop of red from the chrono hands is stunning! The watch wears tall but comfortable. Also love the display case back- can't stop seeing how the chrono mechanism works. Overall very happy with the purchase.

Excellence All Around

"Excellence All Around"

Verified Watch Owner Comments: My experience with WatchBuys was positive throughout, from initial consultation and advice to addressing and solving a fit issue to my complete satisfaction. The watch itself is handsome, a pleasure to wear, and a great timekeeper.

Excellent watch/experience!

"Excellent watch/experience!"

Verified Watch Owner Comments: The Sinn144 is a fantastic watch.

The case shape, matte finish, and matching bracelet gives it a very unique look and feel. It wears small for a 41mm (in my opinion) so don’t be intimidated by a number if you prefer smaller watches. The see through case back and nice movement finishing is a nice contrast to the the very utilitarian/tool watch exterior.

Excellent pre-purchase communication and fast delivery made this another positive watch purchasing experience from Watchbuys!

Purchase with WatchBuys

Verified Watch Owner Comments: I can’t say enough about the company and their products. I recently purchased a Sinn 104 and 144. They exceeded beyond my expectations. When I called in the owner answered.

We spoke for 30 minutes about how we both got started into watches. It’s been my pleasure doing business with WatchBuys. I’ll be lifelong customer.

Verified Watch Owner Comments: This is an excellent watch. I was worried about how the watch would wear, but the curved case back and short lug to lug hides its size very well. It is extremely legible with the color differentiation for the chronograph registers and the tapered bracelet is very comfortable.

The movement is decorated very nicely and is a nice touch with the all business dial. Easily my favorite chronograph, and will buy from Watchbuys again (2nd purchase).
