Seiko 'Tuna' Marinemaster Cermet 1000m LE SBBN029

Released in celebration of the 50th anniversary of Seiko Dive watches, the Tuna Marinemaster features a 49.4mm case constructed of a unique material known as Cermet. This composite material combines the strength of ceramic with the malleability of steel, allowing it to be polished to a mirror finish that is resistant to scratches,

The dial is classic Tuna, being highly legible and despite the large case size it wears very comfortably on the wrist due to its lugless design. It’s powered by the Quartz 7C46 calibre, and is rated to 1000m of water resistance.

This particular piece presents in TZ near-mint condition, with only the lightest hints of wear present. There's the tiniest fleck of dust near 11 under the crystal, but other than that and some tiny marks on the buckle it's almost as-new. That's the beauty of Cermet. Please see images for full condition details.

Battery changed in 2020.

Comes as watch-only due to a recent burglary where the box and papers were unfortunately stolen. Will include a Watch Vault cleaning cloth and Watch Vault travel pod with the sale.
