The Seiko Prospex SPB315J1 “Slim Turtle,” is a compact and modern reinterpretation of the 1968 6105-8000 diver. Its slim 41 mm stainless steel cushion case measures just 12.3 mm thick and wears smaller thanks to a short 46.9 mm lug-to-lug and recessed 4 o’clock crown.

The matte black dial, framed by a curved sapphire crystal, is accented by gold-tone hands and indices filled with vibrant green LumiBrite for excellent legibility. Powered by Seiko’s reliable 6R35 automatic calibre, it delivers a 70-hour power reserve, a discreet date at 4:30, and 200 m water resistance—serious dive capability in a clean, wearable package.
