The recent history of dive watches is all about going deeper and deeper beneath the ocean?s surface. Recent releases (and major technological advancements) from Rolex and Omega underscore the continuing interest on the part of brands, collectors, and, we assume, pro divers in maximizing depth ratings, whether for practical purposes or bragging rights. The watches that come out of the research and development around extreme depth resistance have a certain appeal even if you don?t have a particular desire to even get them wet – they are technological marvels, and often compelling design objects with an offbeat aesthetic appeal. Now, Oris is getting in on the act, with a new member of the Aquis family that goes deeper than any before it, the AquisPro 4000m.
The headline here is right in the name of the watch: this is an Aquis that is rated to an impressive 4,000 meters of water resistance. While not as robust as Omega?s Ultra Deep which is rated to 6,000 meters, or the truly incomprehensible Deepsea Challenge diver by Rolex that goes to 11,000 meters, this Aquis handily beats other divers in the Aquis family, which are typically rated to 300 meters. It does so with an oversized, multi piece titanium case measuring 49.5mm in diameter and a little over 23mm thick. 

I don?t know if there?s an obscure Swiss law that says any dive watch rated over a certain depth rating needs to have some kind of ocean themed dial design, but we get one with the AquisPro 400...
