Seiko Prospex Marinemaster 1968 Heritage Diver's Watch HBF001
The Seiko Prospex Marinemaster 1968 Heritage Diver's Watch HBF001 is a tool watch inspired by Antarctic exploration and Seiko's historical dive watches. It features a textured dial reminiscent of ice cores and design elements from the 1968 Seiko Diver's 300M 6159.
- 42.6mm stainless steel case
- 300 meters of water resistance
- Caliber 8L45 movement
The textured dial design is inspired by the icy conditions of the Antarctic and the mysteries of time studied in ice cores.
It features a unidirectional bezel with a color-matched ceramic insert and large, lumed geometric hour markers inherited from past heritage models.
The watch has a screw-down crown positioned at 4 o'clock.
The Caliber 8L45 movement is noted for its stable accuracy, with a rate of -5 to +10 seconds per day, due to a redesigned SPRON mainspring and other enhancements.
The design pays homage to the 1968 Seiko Diver's 300M 6159, which was a significant advancement over the earlier 62MAS, featuring a higher depth rating and a high-beat movement.
The HBF001 includes an upgraded bracelet with a micro-adjustable clasp.
