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.

This particular piece was purchased locally in 2018 and presents in TZ Near Mint condition, with the only real blemish being a tiny nick on the outer casing near 5. Please see images for full condition details.

No known service history. All functions operate as they should.

Comes with outer sleeve, inner box, Seiko Boutique booklet, instruction booklet, Seiko cleaning cloth, warranty card (expired) and Watch Vault cleaning cloth.
