Over a year ago I waxed poetic on the upcoming Sinn EZM 10 when I introduced the watch here. Later I was able to get my hands on the lovely Teutonic uber watch and I am smitten all over again. Sinn watches holds a special place in my heart because the brand exists in a total bubble. They totally do. They create very useful and durable mechanical watches for a world that probably doesn’t need them as much as Sinn thinks they do. The brand focuses on value, function, and the needs of active professionals who need serious tools in their work. The majority of these professionals probably use inexpensive digital watches, but Sinn likes to ignore that – and bless ’em for it.

I encourage you to check out my first article on the EZM 10 via the link in the paragraph above. There is just a lot to say about this watch that I don’t intend to write twice. The history of the EZM collection as well as of the movement are important, and help enthusiasts understand the role of this watch in the overall Sinn family. What I will repeat is that while the EZM 10 actually has some retro-style design, it mechanically is one of Sinn’s most contemporary creations – incorporating a lot of technology the brand has developed over the years in a single package. In short, some of the best features of the EZM 10 are the DIAPAL escapement, anti-humidity capsule in the dial, sapphire crystal over the bezel, and Tegimented titanium case.

Inside of the Sinn EZM 10 is the Sinn SZ01 automatic movement. It is essentially a heavily modified Swiss ETA Valjoux 7750 that has been beefed up and given some different functions. The dial has the time, 12 hour chronograph with central chronograph seconds and minutes counter, synched 24 hour hand (AM/PM indicator), and the date. Legibility is very good with the high contrast black and white indicators, and the orange adds a little spice to the design. Sinn always uses a remarkable amount of AR coating on the crystal, so glare is really never an issue. The new bezel with its sapphire crystal inlay is quite nice. It does offer a nice little shine which is uncommon in Sinn watches, but I think it is appreciated in this watch.

Sinn pegs the EZM 10 as a “Pilot Chronograph.” Not all Sinn watches are aimed at aviation, but I guess this one is. The watch is still water resistant to 200 meters and is a capable diver. What I found interesting is that the version I checked out has an exhibition caseback. Sinn’s website has the EZM 10 with a solid caseback – which makes more sense for a watch that claims a handsome level of anti-magnetic qualities. It is possible that you can choose either a solid or exhibition caseback. It is hard not to like the chronograph pushers that are flush with the case. Though, it is a matter of taste whether you like them coated in black – but I think they look pretty cool like that. While there is a small recessed area where the crown screws into, there is not a huge level of crown protection as there might be with other watches that have more pronounced crown guards.

On the wrist the EZM 10 is light and comfortable even though it is a larger watch with wide lugs and a 44mm wide size (46.5mm wide with the crown). The case is light because it is in titanium. Not just any titanium, but Sinn’s specially hardened “Tegimented” titanium. I believe that the EZM 10 is the first Sinn watch I noticed that used the Tegimentation process with titanium (in the past it was done only with steel). The bead-blasted finish of the case makes it look extra utilitarian. While Sinn of course offers a titanium bracelet with the EZM 10 as an option, the base strap is actually worth considering. The tough looking leather strap with its orange contrast stitching is both attractive and feels durable. Plus, it goes pretty nicely with the orange on the dial. Funny how no matter how much Sinn tries to be a function-only watch brand, you still see little style details like that which remind us that they actually do care a lot about what their watches look like.

The combination of elements and design in the Sinn EZM 10 make it a really desirable timepiece in my opinion. Sinn actually released a range of very nice watches for 2012, so I expect even better stuff from them next year. The EZM 10 is priced higher than its counterparts given all the little details. Though it still isn’t a wildly expensive watch. In Europe the price for the Sinn EZM 10 ranges from 3,950 – 4,250 Euros. Via the US distributor, the price is $5,670 on the leather strap.
