I still have the Sinn EZM2 Hydro version as used by the German GSG9 divers unit. This watch is a great everyday wear watch made even more comfortable by the mounting of the crown at the
9 position. The watch is titanium with the patented Sinn "silikoninjektion" system allowing for extremely deep submersion.
The watch uses the venerable ETA quartz movement and keeps excellent time. It measures 41mm across and 11.4 mm thick. It is in excellent condition with only a few minor(VERY) scuffs on the bracelet. I purchased this watch from Germany in Apr/May of this year. It comes with all boxes and papers. Reduced to $700 USD.
Thanks for looking
