Extreme divers know the importance of using reliable equipment. The features and design of the EZM 3 model have been created around this mantra.

The EZM 3 is simple to read at a glance and includes a non-losable, unidirectional diver’s bezel among a myriad of features that make this watch so popular with people who deal with tough conditions in, or on, the water.

The EZM 3 is the perfect instrument for extreme divers and water explorers.

In conjunction with its instrument chronographs and watches, Sinn is renowned for its sports and diving watches. Sinn diving watches have lead the way in terms of technical advances for timepieces that must withstand rough and demanding conditions. Thanks to its Argon Gas filling technology, Sinn produces totally condensation-free diving watches. Other special features of Sinn water watches include:

  • Double Gaskets made of highly elastic plastic that remain water tight regardless of pressure
  • Scratch proof sapphire crystal, anti-reflective on both sides to ensure a clear view of the dial at all times
  • Luminous numerals, coated with a special inactive, long-lasting luminous paint
  • Highest possible Magnetic field protection
  • Adjustable bands (stainless steel, titanium, silicon or shark skin) to allow the watch to be worn over a wet or dry suit.

Sinn sport and diver’s watches surpass standard DIN norms for diving watches. In fact, they fulfil the prerequisites of DIN 8306 in which strict safety standards for diver’s watches are precisely and extensively established. Anyone serious about diving or extreme water sports should have the reliability and performance of a Sinn sport or diver’s watch by their side.

The EZM 3 is a mechanical watch built for use during the toughest of dives. The first step in conceiving the EZM 3 was to fill the case with the most inert of all gases, argon, in order to keep oxygen and other aggressive gases at bay. Sinn then added an integrated dehumidifying capsule filled with copper sulphate to absorb unavoidable diffused moisture in the air, which signals its degree of saturation in a small sapphire crystal window. The added benefit of this technology is that it markedly lengthens the period of functionality plus stops the crystal misting over, even under the most extreme temperature conditions. From freezing waters and colder air and back to warm ships this watch can withstand it all thanks to the use of Sinn’s special oil on all bearings, allowing it to withstand temperatures from -45 to +80 degrees C. The EZM 3 has magnetic field protection to 80,000 A/m and will withstand pressure up to 50 bar/500m. As with the GSG 9 model, the crown is set on the left hand side so as not to restrict movement when diving and fittings are large enough that they can be successfully operated when wearing gloves. And perhaps most importantly, the bezel rotates unidirectionally – a vital feature for serious divers. The EZM 3 series is well established and highly regarded by divers across the globe, and the reasons are obvious.
