Sinn EZM 10 Watch

Sinn EZM 10 Watch Watch Releases

This will be German Sinn’s new flagship rough activity watch, and the tenth watch to bear the EZM title. I quite love this watch and further find it interesting that it is quite retro in design in comparison to where the EZM series was going. Though not like 1950’s retro – which is a darn good thing. Nevertheless, the piece contains some great modern technology and will make Sinn fans and newbies to the brand alike want one.

“EZM” stands for “Einsatzzeitmesser” which means “mission timer.” These are among Sinn’s more serious pieces and have been delighting both collectors and the people that really need them for years. The release of a new EZM watch is always cause for pause. As of writing this article, the Sinn EZM 10 is still in “pre-official announcement mode.” I will update this article with more details and images as they become available – so sorry for the fuzzy looking scan.

The look and design of this watch feels like something out of the Lemania 5100 movement days. Even the movement is meant to remind you of the Lemania 5100 I feel – which may very well be what Sinn modified or used as a base design for the movement – or something similar to that. Sinn is calling the automatic movement their caliber SZ01. We will get more details on that soon. Offering a cool tri-compax subdial array, the chronograph features a central seconds and minutes indicator (yay!), as well as a subdial for the chronograph hours. There are also subdials for the time seconds and a synchronized 24 hour indicator (AM/PM indicator more or less). Beautifully symmetrical, the dial is both legible and packed with useful features. There is also a date indicator of course.

Also very important is that the movement features Sinn’s coveted DIAPAL technology which uses a lubrication-free escapement. This is also one of the first Sinn DIAPAL (diamond palette) watches that does not have the metallic gray dial, but rather a more traditional black dial.

Don’t you love those almost Tutima-style inset chronograph pushers on the case? They offer a clean look, but also tend to be easy to operate. The case is 44mm wide in tegimented titanium. Tegimented steel is a material Sinn uses that is treated to be much harder than steel. This is the first time I have seen Sinn offer tegimented titanium. As titanium is a tough, but soft metal, I am curious to know how this affects its scratch resistance.  The chronograph pushers are done in PVD black. Overall I think the case material is just one of the Sinn EZM 10’s strong points.


Over the rotating bezel is a sapphire crystal insert. Another first for Sinn, following suit with brands like Blancpain and Bremont who offer this to the delight of wearers. Sapphire crystal on bezels gives them a nice mixture of legibility and durability. Given that it is an EZM model, the case will have all the requisite “super man watch” technologies such as being highly water resistant, temperature resistant (-45 degrees C – +80 degrees C), have Sinn’s anti humidity (Ar technology) feature, be highly anti-magnetic, and also be very shock resistant.  Also worth mentioning is how the EZM 10 watch comes with a 5 year warranty.

Sinn will offer the EZM 10 on at least two strap options (leather or silicone) and on a titanium bracelet. I love the functionality, the sort of retro looks of the watch (more like 1970s retro if anything), and of course the durability. This is gonna be the new grail Sinn piece for many people. According to Sinn it will be available in November 2011. Price? Higher than most Sinn watches but perhaps worth it given all the next features and the technology. Prices start at 3,950 Euros on the leather strap, to 4,170 Euros on a silicone strap (must be some strap), and 4,250 Euros on the titanium bracelet. Check for updates on this Germanic beauty soon.

  • It’s a modified 7750 – from


    The first chronograph to be developed by Sinn on the basis of the Valjoux 7750.
    To improve its readability we redesigned the Valjoux 7750, under the name SZ01. The movement now has a jump-action minute counter from the center of the dial.

    Our new design has two advantages in terms of readability: firstly, 60 instead of the usual 30 minutes are now counted in one rotation; secondly, the minute stopwatch scale is visible around the entire dial circumference. The SZ01 has a similarly high degree of readability to the Lemania 5100, which is no longer in production. The military approval of the Lemania caliber was based primarily on this particular property. The movement also has a 24-hour display at 3 o’clock and a date display between 4 and 5 o’clock .”

    • Oh, good to know.

  • Ulysses

    Now that’s a really nice Sinn – perhaps they are trying to prove to some that they are not a “boring” brand.

  • Dangeruss

    Yeah! I like that a lot. That’s two new Sinns that you’ve shown that I now have on my wishlist. I wish I had a spare $5500 to toss at it.

  • Simon T.

    Why is the bezel markers going counterclockwise?

    • Dean

      Certainly can’t be used as a “dive-watch” now can it.

      In fact what use is that bezel at all?

  • I really like the look of that, pricey, but cool.

  • Holger

    Looks like Sinn and Damasko share the same designer. The Damakso DC 86 looks remarkably similar.

  • Dean Grant Baker

    How much for a 7750?
    4250 Euros = 5 763.1832 Canadian dollars?

    You can get into a Sub or Speedy for that.
    I paid less than 400CDN$ for an Accutron vx 200M [NIB] with a 7750.
    and guess what?
    Accutron has a FIVE YEAR WARRANTY.

    Are you joking? Those prices are typos? Yes?

    And add to that SINN won’t be getting ANY [ETA] spare parts after 2012.

    You’d have to be an UTTER FOOL to buy a SINN with an E.T.A., let alone pay nearly — 6 000 dollars —–, Oh? And, don’t forget taxes and delivery.

    • Dean

      4250 Euros = 5 813.15 U.S. dollars

    • Andrew

      I disagree.

      There are Citizens and Casios for people who aren’t looking for premium products. For those who are – this is the market price. If you can’t swing it, look at Swiss Army and Chase Durer with ETA 251.262 quartz.

      Countdown bezel with sapphire, modified movement based on one of the most robust chronographs, updated lemania 5100-style layout (only other auto I’ve seen is a Breitling Skyracer Raven – also about $5k), and freakin TEGIMENTED TITANIUM?

      Thank you Sinn. . . this is my dream watch. I’ll be working my a$$ off to buy one in the coming year.

  • Arthur Davis

    Come to me my precious. Watch porn at its finest. (cue wah wah guitar) like the retro feel. getting a little pricey but worth it. I have an Omega Seamaster PO 1st generation i love it. saving up for another great piece. this one is getting out of my league though. OH why must you taunt us with such fabulous wrist wear! whats with ETA admin, not selling parts?

  • Dean Grant Baker

    for 6 000 the watch had better have applied indices and not painted — ooops.
    “tegimented” is a term invented by SINN, it is no more or less special than any other proprietory hardening eg: Duratect, DLC’s, or cold hardening or annealing by heat or chemicals.

    • Andrew

      Isnt DLC a coating like PVD – not really changing the substrate?

      I also think Sinn’s hardened steel is the same used in submarine hulls – kinda unique compared to other processes.

      Either way, I applaud Sinn for bringing hardened titanium to the market – anybody whose ever messed with the stuff knows it is totally different than steel.

  • kris.c

    Very nice. I’m not much of a Sinn fan boi, many of thier pieces strike me as kinda boring, but this is quite nice. I do live the integrated chrono pushers, and I know the Sinn build quality to be very high.
    Are we sure this one has the anti humidity technology in it? Normally those Sinn pieces have the “Ar” logo on the dial.

    That strap though… *shudder*. Dreadful. As long as the silicone does not have a giant Sinn logo on it (like many do) and comes withthe beefy butterfly deployment, I’d want that. Or of course the bracelet.

  • Peter Alsop

    At long last Sinn produce a pilot chronograph with a Lemania 5100 style chronograph display. I used to own a Sinn 157 but it was stolen in Barbados in 2006 so I’ve something to replace it with now. The price will be a sticking point, I’ll wait and see how much the Damasko DC 86 will be retailing for before making a decision in 2012.
