With a case referred to as a "compressor," this specific design was based around a case that became more water resistant as you went deeper because the caseback would pressurize further the deeper you went (max 600 feet). Other features included two crowns, of which one rotated an inner timing bezel instead of an external bezel, as found in most watches of the time. The style makes for a much cleaner look with less chance of mistakenly shifting the bezel ensuring unparalleled accuracy underwater.

Standout features that make the BENRUS Ultra-Deep significant are the use of incredibly cool cathedral-style hour and minute hands as well as the inclusion of a date window with an internal magnification eye. In recreating this iconic timepiece and while always looking to preserve or improve the original in performance with updates to current technologies and manufacturing, these design details were faithfully maintained along with the original and versatile size of 36.5mm

Mystery Shipwreck Dive
with the Ultra-Deep

“Underwater the watch was supremely legible—its cream on black dial and distinctive hands left no doubt as to my bottom time. I’ve said it before: a dive watch is a simple creature with a simple job—track elapsed time legibly and accurately in all conditions, and don’t leak. Though the depth of the shipwreck wasn’t even close to the watch’s depth rating, cold water can play havoc with equipment, and I’ll admit to a lingering concern about the non-locking crown that controls the timing ring. This turned out to be unfounded as the watch emerged unscathed after two back-to-back dives, living up to its Ultra-Deep name.”
