Seiko Prospex MarineMaster 'Tuna' SBBN035

Seiko manufacture some of the coolest, most historically significant and toughest dive watches out there, and the Tuna line encapsulates all of these traits to a tee. Every watch collector should experience a Tuna at some point!

Featuring a very distinctive 47.7mm PVD-coated steel case, it wears smaller than this size would suggest, especially in all black as the SBBN035 is. It is almost a lugless design, so the traditional lug-to-lug measurement is a few mm smaller than most 42mm dive watches. Within this case lies a black dial with large luminous plots, and heavily lumed hands, with day and date complication. It's surrounded by a uni-directional dive bezel that is then protected by the Tuna PVD-steel outer casing. It's powered by the high-torque quartz caliber 7C46, and mounted to the supple silicone Seiko strap with PVD's hardware.
