SEIKO PROSPEX TORTOISE BLACK SERIES LIMITED EDITION AUTOMATIC DIVER'S WATCH – 42.4MM DARK GREY DIAL SILICONE STRAP
SRPH99K1
The Seiko Prospex Tortoise is the softer, more rounded alternative to the angular Samurai — and the Black Series SRPH99K1 takes it to its darkest possible expression. A hard-coated black case contains a matte dark grey dial, lit with green Lumibrite lume that becomes the watch's defining feature the moment the lights go out. The sapphire crystal is a meaningful upgrade for a diver of this calibre, and the rotating aluminium bezel insert completes a package built without compromise.
Why This Watch Stands Out
- Black Series Tortoise — the iconic rounded Prospex case in full stealth black hard coating
- Sapphire crystal — a premium spec that adds scratch resistance over standard hardlex
- Green Lumibrite on matte grey dial — the green lume glows dramatically in low-light conditions
- Seiko Calibre 4R35 automatic — 41-hour power reserve, hand-wind and hack
- 200-metre diver's water resistance with screw-down crown and unidirectional rotating bezel
