M2 Seven Seas S
Steel. 500 meters. Cal. 330. Two sizes — 40mm and 44mm.
500 meters. The kind of depth rating that means you stop thinking about it — swimming, diving, caught in the rain, forgot to take it off in the shower. It handles all of it. 316L stainless steel. 40mm case, 12.5mm height — substantial on the wrist without dominating it. Cal. 330 automatic. Screw-in crown. Unidirectional bezel with 60 clicks. FKM rubber strap or steel bracelet. The same 500-meter architecture as the titanium Seven Seas, in a steel case at a lower price point. Put it on in the morning; at 12.5mm, it disappears under a shirt cuff.
500 meters in steel. 12.5mm tall. Disappears under a shirt cuff.
