Product Details

The Sinn EZM 3 Flieger takes its design cues from the Sinn EZM 3 (a diver's watch).

Although the case size and overall construction are the same, the dial, bezel and water resistance differ.

The original Sinn EZM 3 diver's watch was released in 2001 and remains a bestseller to this day.

Over the years both we and Sinn have received many requests for an alternate version of this watch, namely a cleaner dial with no numerals and a pilot's countdown bezel.

The Sinn EZM 3 Flieger is that watch and results from direct feedback from Sinn's customers.

This watch will not replace the current Sinn EZM 3 - both will coexist with one designed for divers and one for pilots.

Dial and Bezel Design

The Sinn EZM 3 Flieger features a clean and highly legible dial with no numerals.  The five minute indices are coated with SuperLuminova for excellent visibility at night.

The pilot's bezel is ratcheting bi-directional and of a "count down" design (55 is to the right of 12).

Another difference is the date - Sinn has made the date indication in white rather than red for increased legibility.

The Anti-Magnetic Case

The case has an iron core to protect against extreme magnetic fields. Sand-blasted stainless steel case with reversed screw down crown and matte black dial with luminous hands and markings.

This watch is water resistant to 200 meters.

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).

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.

Watch Reviews From Verified WatchBuys Buyers
100% • Verified Watch Owner Reviews100% • Verified Watch Owner Reviews (5 reviews)



Verified Watch Owner Comments: This is the second ezm3f I bought from WB. The first one was in 2016 and a medical situation forced me to sell, I was determined to pick up another one, it took a while but I managed to do it. This is a very well made watch at an outstanding price point.

Fit and finish is equal to and better than the price comparison of similar brands I have owned. This has the right look for me which is a military style, diver-pilot, this is what I want to see when looking at my wrist. Sinn knocks it out of the park with this one. The only thing I would change is offer it in a right crown version and add more clasp hole adjustments.

The guys at watchbuys are awesome, very informed and helpful plus they actually take the time to listen to the customer. Thanks for another amazing Sinn

Underrated watch

"Underrated watch"

Verified Watch Owner Comments: The SIN 104 often gets compared to Damasko watches but the EZM 3 sand blasted finish is probably closer to Damasko cases. Many people mention the date color of the EZM 3F vs the EZM 3 but I believe the dial and bezel numbers should be a bigger deciding factor the two. The crown being on the left is comfortable and the lume though only on the hours is consistently my brightest watch lume. Also the bidirectional bezel is cool.

A concern for me was the cost of inert gas and maintenance. Watchbuys answered all my questions. The miss on that watch is the leather strap. Those with larger wrist will want to swap it out. The H-link bracelet is great but I think most people should put it on a fully tegiminted watch so they don't have buyer remorse. The silicon band looks cool but it is more than I wanted to spend as I have purchased a fully tegiminted U1 as my first Sinn watch. I ordered a Hirsh Robby strap which I believe will be better suited for the watch.

Great Watch

"Great Watch"

Verified Watch Owner Comments: This is a great piece! The dial is a matte black that looks really nice in person.

Watchbuys was nice to work with. They called prior to the shipment to confirm my information. Well done!

EZM 3F Leather

"EZM 3F Leather"

Verified Watch Owner Comments: At first concerning when it was clear that Watchbuys was the only legit option for me in the US, but the customer service and the ease of ordering experience were exceptional. I felt quickly as though I had a trusted friend in the business, the buying experience was that good. After months of research I had finally Settled on the 3F versus the 3 due to the bidirectional bezel, which seems more functional to me. I will never be a diver nor a pilot but those key functional aspects were important and the 3F seemed the best of both. The leather band was a bit of an unknown. I had no leather band experience but it struck me as a bit of variety in the collection as well as being dressier. Opening the box I was slightly underwhelmed. The strap is good quality but smaller than I imagined. After a day on the wrist though, I appreciate its size and comfort more than I did at first. Still, I likely will supplement with a bracelet or rubber band soon, putting the Watchbuys points to use. Lume ... - more details

EZM3F My Favorite watch!

"EZM3F My Favorite watch!"

Verified Watch Owner Comments: This has become my favorite watch! Form Follows Function puts crown at 9 position. I love it! Looks great w/ leather strap, due to heat wave, changed to rubber strap. At 41mm OD, it's truer to the EZM1, and my wrist! I will cherish the EZM1.1 at 43mm OD I have on order. Unless I use chronograph a lot, I can't tell which watch will be on my wrist the most!

THANK YOU SINN for producing a EZM3 with a much cleaner dial design. Rated at ONLY: 20BAR, 200m, 660ft! This is a relatively thin watch, (11.7mm), I don't have to think about if I jump into a pool, or on vacation. Isn't that why most of us own a Divers watch? Superb build quality it's that good!
