Seiko Prospex Marinemaster 1965 Diver’s Modern Re-interpretation

The Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation is noted for its slim 12.3mm case and 39.5mm diameter, making it a wearable dive watch.

The watch features a box-shaped sapphire crystal and 200 meters of water resistance.
