Seiko Prospex Diver's Sea Arctic Ocean GMT Limited Edition 42mm Mens Watch Silver SPB439J1
£1,600.00Prospex 'Arctic Ocean' - Save the Ocean GMT
There are just 1,500 pieces of this limited edition 1968 Seiko mechanical diver's re-interpretation available worldwide.
Inspired by the need to protect and preserve the Arctic Ocean, the silver-coloured textured dial of this watch depicts the surface of an ice glacier, whilst the GMT hand and 24-hour scale are in a striking 'Arctic Blue' shade to resemble the harsh sea.
A proportion of proceeds from this timepiece will be given back to the PADI® and PADI Aware Foundation's Marine Debris Program to rid the ocean of marine debris.
This piece is powered by the 6R54 movement, which is the first Seiko Prospex Diver's mechanical GMT movement to have GMT functionality and a long three-day power reserve. The GMT functionality allows the wearer to track multiple time zones at once.
The rotating bezel of this piece is made from high quality scratch-resistant Japanese ceramic whilst its low centre of gravity and short-pitch bracelet have been designed for a comfortable fit.
Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
