SINN UX EZM2 HYDRO Mens Deep Diver Special Forces Stainless Steel Watch - Box & Papers
Gorgeous Original Condition with Box & Papers - Oil Filled Design - 1 Year Warranty
Developed in collaboration with Germany’s elite counter-terrorism and special forces unit, GSG 9, the Sinn 403.GSG9 HYDRO EZM2 is a professional mission-timer built with robust capabilities. EZM stands for Einsatz Zeit Messer, which translates to English as Mission Timer.
Its defining innovation is Sinn’s HYDRO technology: the entire case is filled with oil, eliminating internal air and making the watch extremely legible underwater from every angle, fog-proof, and immune to crushing pressure differentials. The result is an instrument trusted by professionals whose lives depend on it.
It's a really cool watch, and one we couldn't pass up when it was offered to us with original box and papers in nearly new condition.
Why quartz—and why it matters:
To achieve this feat, Sinn turned to quartz. An oil-filled case requires fluid to permeate every recess of the movement as well as the case, something a mechanical escapement cannot tolerate. (Brands like Ressence get part-way there with half-filled displays, but the mechanical heart remains sealed off in a dry capsule. Sinn completely submerged the quartz movement itself in oil.)
How deep is “too deep”?
HYDRO technology makes the case itself effectively unconcerned with depth. Sinn later certified the UX (EZM 2B) as pressure-resistant to an extraordinary 12,000 meters—deeper than any point on Earth’s oceans. Ironically, it isn’t the case but the quartz movement that sets the limit: rated to 5,000 meters, which is why “5000 m” appears on UX dials. The 403.GSG9 demonstrates the same underlying innovation, giving it credibility few other divers can match.
Details that matter in the field:
The crown sits on the left side at 10 o’clock, an ergonomic decision that keeps it from digging into the wrist, catching on gear, or being knocked in mission use. A thermal-expansion membrane on the caseback absorbs the natural volume change of the oil across extreme temperatures, keeping the crystal safe and the watch reliable. With oil in contact with the underside of the sapphire crystal, reflections vanish and underwater readability is unmatched.
Our Hyrdro:
As I mentioned, our example is in gorgeous original condition, a 9.7 out of 10. The back has some tiny remnants of wear - otherwise the watch presents as like new. Its dial and crystal both present like new.
It comes complete with its original Sinn “Einsatzzeitmesser 403.GSG9 HYDRO” presentation box and papers—rare to find intact and highly prized among collectors.
A Master Watchmaker has installed a new battery and performed any needed servicing making. For the finishing touch we have installed a brand new calfskin strap and meticulously detailed it making it ready for immediate enjoyment.
Why collectors want it:
Among the countless “dive-inspired” watches, only Sinn rewrote the medium itself by filling the watch with oil. The result is a professional instrument with peerless underwater performance, mission pedigree, and a design built around solving real problems. Combined with its nearly new condition and complete set, this 403.GSG9 is one of the more compelling and conversation-worthy divers available.
Your watch is important to us, and we will take care of it for its lifetime. We provide the best after sale care in the business with an extremely experienced team of four Master Watchmakers all of whom each have over thirty-five years of experience and a large number of parts. One used to be the watchmaker for an authorized Rolex dealership and was given training by Rolex at their Beverly Hills Service Center.
