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.
This watch has been certified by DNV and tested in accordance with European diving equipment standards. Additionally, it features a crown located at the 4 o’clock position to prevent pressure on the back of the hand. Comes with a seven year battery and anti-reflective sapphire crystal.
