Deepest divers watch

[michael_JCWS]

Any thoughts? Bell & Ross hydro max?

[bigandclever]

Sinn UX is rated to (I think) 12000 metres - which is deeper than the deepest place on Earth.

Doesn't the Sinn have no theoretical max depth? IIRC it's filled with oil (and therefore incompressible.)

The CX Swiss is rated to 20000ft (~6000m) and is mechanical, unlike the Sinn & B&R (which are quartz).

I think the only watch actually tested in the sea is the Rolex Deepsea

What depth, out of interest? Sure I've seen a pic of a sub strapped to an rov showing a depth of >1000m

The B&R Hydromax, Sinn EZM2 and UX (along with a few other silicon/teflon oil watches like the Beuchat Abyss) all go to about 12000m+, the Sinn is rated at 5000m as it was found that a node in the quartz module eventually collapsed at around that point or was only rated for that pressure technically.
Quartz obviously, but the UX is thermo-compensated; I don't know about the B&R/EZM2.
There are a few different ways to allow volume compensaton for undissolved gas appearing with a high temperature differential; diaphram for B&R and piston for Sinn (iirc).
For servicing they have to go back to the factory, and at some stage a small bubble (see 12 o'clock on the Hydromax) may appear in colder temperatures - this doesn't affect timekeeping or harm the watch and may disappear again when warmed back up.
My favourite is the Sinn EZM2, which I think someone on here has, it's a nice version too, with the black bezel and red date (again iirc!).

Thinks mine's rated at 3900m or 12,800ft IIRC, sorry can't be bothered to take it off the self winder at this time of night.

35800ft, at the bottom of the 'Marianas Trench' in the Pacific.

Here's just about everything you need to know on the descent, and the people involved...

SDW/Hypertec Hyperbars are oil filled and rated at 12000M for not very much.

Had one a while back that I picked up under a hundred on the bay of tat.
