Extreme Dive Watches from TechnoMarine, Bell & Ross, MTM, and Sinn

There is, as you might expect, some impressive engineering going on in this timepiece. In additional to an oil-filled case, the caseback of the Ulysse Nardin replica watches has a rubber button which helps accommodate the changing properties of the oil under extreme temperatures and depths. The button can become convex or concave as the oil expands or contracts. While I will concede that a $2,400 watch that can go as deep as one of the deepest points in the ocean may be a little overkill, the watch is more of a proof of concept and a brand statement for Bell & Ross professional watches.TechnoMarine AbyssDive watches come in all shapes and sizes, and are available at all different price points. Most watches with a uni-directional rotating bezel and the ability to fit over a wetsuit claim more water resistance then most of us will ever need: usually around 100-200 meters. But the better ugg I cover in this article go way deeper than your typical diver; deeper than the current 1,220 meter Rolex Sea Dweller; deeper, even, than the Breitling Steelfish which maxes out at a comparably casual 2,000 meters. There are a handful of watches out there that can literally scrape the bottom of the deepest known parts of the ocean, and I call these watches "extreme divers".The TechnoMarine AbyssFirst up is the TechnoMarine Abyss. This avant-garde brand throws down an interesting looking Ulysse Nardin that is ready to dive. The Abyss is a 42.5mm quartz-powered stainless steel dive watch which, at $650, represents the cheapest of the extreme divers. Although suspiciously light on details, TechnoMarine claims the Abyss can withstand 12,000 meters of water, or about 39,600 feet, which is about as deep as deep gets. This model comes in a choice of dial colors (blue, black, orange, silver, and yellow), and is outfitted with a mineral crystal. Something that sets the Abyss apart from the other extreme divers is the day of the week in additional to the date. Like all the extreme divers, the case of the Abyss is filled with silicone oil to keep the pressure equalized, and it has a very prominent air bubble which will undoubtedly draw bewildered looks and plenty of questions from perfect strangers. The Bell & Ross HydromaxBell & Ross HydromaxMTM Black SealSinn UXBell & Ross has a beauty of a diver called the Hydromax which they claim (and back up with details) will withstand a depth of 11,100 meters, or about 36,500 feet. While not the most extreme of the extreme divers, that still makes it capable of reaching the bottom of Challenger Trench, one of the deepest known points in the ocean.
