SEIKO PROSPEX BLACK SERIES LIMITED EDITION - SPB255J1

SEIKO PROSPEX BLACK SERIES LIMITED TO 5,500 PIECES

Seiko Prospex Black Series L.E. SPB255J1, taking inspiration from the 1968 Seiko ref 6159-7001. Another important piece in Seiko’s dive watch history, this moves the crown to 4 o’clock, has a larger diameter compared to the 62MAS and pretty much laid the foundation for the brand’s design ethos for dive watches.

The case is again done in black coated stainless steel but measures 42mm across and 12.5mm in height. We again see a black dial with large, applied roundels for the hours and a set of black hands. Contrast comes from the use of different colours for the diving scale on the bezel and the hands for instance. It uses the same automatic movement as the other two, so no changes there. The 6R35 calibre uses 24 jewels and runs at 21,600vph. We again see the brown textile strap with black hardware, and the rubber strap as an alternative.
