Collection: M2 Seven Seas

The Seven Seas puts the M2 case underwater. Pure titanium, 44mm, a sapphire crystal three millimetres thick, and a screwed crown and back that together hold fifty bar.

The bezel turns in one direction only, so an intended bottom time cannot be lengthened by accident. Caliber Tutima 330 inside, its rotor finished in antique grey and sealed in 750 gold.
