Seamaster Planet Ocean
A robust diver's watch designed for serious aquatic adventures. With its professional-grade water resistance and bold design, it's built for underwater exploration.
"No GMT, no complication surcharge — from €8,400 for a genuinely serious diver."
42mm is the size I'd steer toward for anyone who's tried the 45.5mm Ultra Deep cases and found the wrist presence overwhelming — the Planet Ocean design survives the size reduction better than most dive watches do. Black dial on a matching steel bracelet keeps this the most conservative reading of the line, no ceramic, no color statement, just the case shape doing the talking. Caliber 8912 underneath is the same manufacture architecture as the bigger references, so you're not trading down on engineering for the smaller footprint. At ~€8,400 it's priced as the accessible steel entry point, and on proportions alone it's the one I'd recommend over the 45.5mm versions.
