Seamaster Planet Ocean 600m
The modern diving watch that excels in extreme conditions. Its robust design and Co-Axial movement make it the ideal companion for underwater adventures.
"600m water resistance, a 60-hour in-house Co-Axial movement, and a chunkier tool-watch presence than the Diver 300M — built for bigger wrists."
At 43.5mm this is the size I point people to when they want Planet Ocean presence without the ultra-deep case heights — it's the proportion that actually sits well under a cuff. The grey dial on rubber keeps things low-key, and caliber 8900 gives you the manufacture Co-Axial architecture without the price climbing into the ultra-deep tier. 600m is already more depth capability than anyone catalogued at that price will use, but that's true of nearly every serious dive watch — the number matters less than the movement finishing underneath it. Around €7,800, it's priced like what it is: the accessible end of the range, not a compromise.
