For those interested in watches I just published a set of photos on Flickr of my Omega Seamaster Planet Ocean. There's a lot of amazing tech that goes into an Omega dive watch and the Planet Ocean is no exception. It features a decompression system that allows the watch casing to off-gas helium after the watch has been in a pressure chamber for a long time. Also on board are Omega's own self-winding Caliber 2500 automatic movement (or the Caliber 9300 if you have the new 2011 edition) with a 48 hour power reserve, an anti-reflective, scratch-resistant sapphire crystal, and a self-locking screw-in crown. All of this in a watch that can go as deep as 600 meters (2,000 feet). View the photos here or watch a slideshow of the photos here.
For such an amazing and timeless product, the Rolex site delivers and equally amazing Web site. My only complaint is the Sea-Dweller not being part of the Extraordinary Watches section. The Sea-Dweller includes all the technical marvels of the Oyster Perpetual movement with the additional ability to be submerged to 1,220 meters (4,000 feet). Also included are the Oyster fliplock bracelet (allowing the piece to be worn over a wet suit) and the helium gas escape valve (necessary for those spending time in a helium-enriched underwater habitat). These technial feats, which are unmatched by any other timepiece, should justify its placement in the Extraordinary Watches category.
