Seiko Prospex 'Darth Tuna' Divers Watch 1000M Quartz S23631J

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 49.4mm case, it wears smaller than this size would suggest, especially in all black as the S23631J is. It is almost a lugless design, so the traditional lug-to-lug measurement is a few mm smaller than most 42mm dive watches. The case is manufacturers in ceramic and titanium, with a monster 1000m of water resistance.

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 ceramic outer casing. Powering it is the high-torque quartz caliber 7C46, and this example is fitted to an aftermarket PVD bracelet which looks and feels great. It is also supplied with the original silicone Seiko strap with PVD hardware

This particular piece was purchased locally in October 2024 and presents in TZ 'Near Mint' condition, with the only blemish being some very minor strap change marks on the PVD coated case back. Please see images for full condition details.

All functions operate as they should, and remains under manufacturers warranty.

Comes with outer box, inner box, hang tag, warranty detail printout and OEM silicone strap.

RRP is $4,300 - save on this near-new example.
