A modern take on one of Seiko’s most recognizable dive watches: the Captain Willard, dressed in Seiko’s bold Black Series style. 🖤
This is the Seiko Prospex SPB257, a limited edition of 5,500 pieces worldwide. Its black-coated 42.7 mm stainless steel case, textured dark dial, and orange seconds hand give it a distinctive look, while the 1970-inspired cushion case and signature crown guard keep the classic Willard character intact.
Inside is Seiko’s automatic 6R35 movement, with hand-winding, hacking seconds, a date display, and approximately 70 hours of power reserve. It also has a curved sapphire crystal, LumiBrite, a unidirectional rotating bezel, and 200 m diver’s water resistance.
Fun fact: the original 1970 Seiko diver that inspired this design was worn by Japanese adventurer Naomi Uemura during his 12,000 km solo dogsled journey from Greenland to Alaska.
The one I have in stock is in mint condition, serial number 0063/5500. It comes with the box and NATO strap; it is not a full presentation set.
