Pre-Owned: Seiko Prospex SBDX014G Marinemaster Emperor Tuna
This is a serious dive watch that means business. As its name states the watch has a depth rating of 1000m, which makes it suitable for saturation diving.
One interesting feature of the Marinemaster is the lack of a Helium Escape Valve (HEV) on the case. This due to the specially designed L-shaped gasket and screw-down glass fixing ring which keeps helium out of the case.
The case is made from Titanium. Seiko was the first company in the world to make a dive watch from Titanium in 1975.
This new version of the Marinemaster has a shroud made from ceramic. This helps to prevent the case from suffering shocks and stops the unidirectional bezel from being shifted accidentally. This new rose gold colored version, will be most likely christened the “Rose Gold Emperor Tuna” by collectors because of distinctive case shape, the depth rating and the color of the bezel, crown and screws holding the shroud in place. The “Tuna” moniker came about because collectors thought the case shape resembled a can of tuna. The watch is 48.2mm in diameter and has a thickness of 17.4mm.
