Sinn UX Dive Watch

Sinn UX Sinn UX 12,000 meters (39,600 feet)

This deep dive watch vying for supremacy is the Sinn UX.

This one, like the Bell and Ross Hydromax is a quartz driven oil filled watch.

Sinn points out some of the advantages of using an oil filled case:

“the watch is absolutely free of fogging, because there is no air inside the case, its pressure-resistant at any accessible diving depth and has perfect readability from any angle under water…Functionally reliable at temperatures from -20 °C to + 60 °C

The Sinn’s aesthetics have a sober sense of purpose and utility to them, it uses Submarine Steel for the watch case and to further toughen this it is hardened using a special process called “Tegimenting”.

After the steel has gone through this process it has a hardness of 1200 Vickers (not Vicars), what does that mean? Well, steel typically has a hardness of 220 Vickers so its nearly 6 times harder.

Comes with a seven year battery and anti-reflective sapphire crystal.
