Seiko Prospex Black Series 1970 Limited Edition 2022

This Seiko Prospex Black Series 1970 Re-interpretation is a Limited Edition of just 1,000 pieces. Now in its fourth year of limited edition release, the popular Black Series takes its inspiration from night diving. The 2022 Series has its roots in three key moments from Seiko’s diving heritage – 1965, 1968 and 1970. This particular design is a modern version of the 1970 timepiece (view the other 1970 “Willard” re-interpretation on a brown strap here).

1970 “Captain Willard”

The 1970 Diver’s timepiece was named ‘Captain Willard’ by fans after Martin Sheen’s character in ‘Apocalypse Now’. Also, Japanese explorer Naomi Uemura wore the original 1970 Diver’s timepiece to climb the highest peaks of each five continents – the first man in the world to do so.

Case, Dial, Bracelet

Firstly, water resistant to 200 m/660 ft the 44mm case is in black stainless steel. Secondly, the black dial expresses the texture of sand on the sea bed. The orange seconds hand adds a subtle and quiet accent. Also, high-visibility hour markers and hands coated in Lumibrite make reading the time in the dark easy. Additionally, a legible minute track is at the extreme edge of the dial. Furthermore, a uni-directional turning bezel surrounds the dial. Moreover, a black stainless steel bracelet secures the watch to the wrist. Finally, the watch is presented in a Limited Edition box with an additional black silicone strap.

Equipped with an automatic 8L35 calibre movement, the Seiko Prospex Black Series 1970 “Willard” Limited Edition is a must for anyone looking for a well-built, practical Diver’s watch. Also, a two year manufacturer’s warranty guarantees peace of mind.
