In a 2022 forum post, @lberti introduced the new OMEGA Seamaster Planet Ocean Ultra Deep in Titanium, sparking immediate discussion among collectors. His initial impressions, drawing comparisons to other robust dive watches, set the stage for a community-wide evaluation of OMEGA's latest deep-diving innovation. This article synthesizes the community's insights, offering a comprehensive look at the watch's design, technical prowess, and market positioning.



The Sea-Dweller reference 116600 marked the return of the 40mm case size for the model, a dimension that had been absent from the Sea-Dweller lineup for some time. This reference reintroduced several classic Sea-Dweller design elements, distinguishing it from its larger contemporary, the Sea-Dweller 4000. It was produced for a relatively short period, making it a notable transitional model within the brand's professional tool watch offerings.
This reference features a stainless steel case measuring 40mm in diameter and 15.3mm in thickness. It is equipped with a unidirectional rotating bezel made of black ceramic with a 60-minute graduation. The watch is powered by the automatic caliber 3135, offering a power reserve of approximately 48 hours. A sapphire crystal protects the black dial, which includes a date complication without the cyclops lens, a characteristic feature of the Sea-Dweller line.
Appealing to collectors who appreciate traditional proportions and the technical capabilities of a professional dive watch, the 116600 is recognized for its blend of heritage design and modern materials. Its limited production run contributes to its appeal among enthusiasts seeking a Sea-Dweller with a more classic case size and specific aesthetic details, such as the matte-like black dial and the absence of the cyclops over the date.
This one is to be tested in person: 45mm and 18mm height is not for everyone...
Any idea whatβs the weight of the SS version with full bracelet? Am not sure if I can lift my wrist to tell time! Jokes aside, itβs an engineering marvel to behold
...but it seems far too thick for comfort (and I own and love the Deepsea!).
Can I wear it? Probably not!
I guess for that, thickness doesnt really matter.
... with pleasure π
