Omega Seamaster Planet Ocean 600M

The Seamaster 300, introduced in 1957, was Omega's response to the burgeoning popularity of SCUBA diving.  Featuring robust steel cases with a 300-meter depth rating, rotating bezels graduated with dive-timing scales, and a metal bracelet with diver's expansion links, the early Seamaster 300s were not only functional divers that would go on to see use in Her Majesty's Navy, but are arguably some of the handsomest sports watch designs of the past century. As it evolved, the Omega Seamaster 300 went on to see numerous evolutionary changes — in fact, nearly innumerable variants in a wide variety of materials and colorways have been produced in the past 60 years. This fact alone has made the Seamaster Professional line incredibly desirable — simply because they don't all look exactly the same. One of the latest additions to the broader Seamaster collection is the Planet Ocean. Introduced in 2005, these watches features a chunkier case, a fresh bracelet design, revised design language on the dial with a 'broad arrow' handset, and increased water resistance — no doubt to compete with that of the Rolex Sea-Dweller. This particular piece, a reference 2900.50.91, is a first-gen Planet Ocean dating to the 2000s that was featured in Casino Royale. Featuring a 45.5mm twisted-lug case, a matte black dial with matching 'broad arrow' handset, a signed stainless steel multi-link bracelet with a signed steel clasp, and the always-controversial helium escape valve at 10:00, these early Planet Oceans are aging quite well and truly hit the sweet spot with respect to design, proportions, and wearability. Although large at the time, it's surprisingly versatile for daily wear.  After all: If it was good enough for a certain Agent 007 on the silver screen back in 2006, then it's certainly good enough for us!
