WHAT WE LOVE:

The Seiko 'Tuna', so-called due to its case shape and size, was designed specifically for saturation diving - a working environment that is up there with the toughest on the planet. This particular configuration was introduced in the 1970s and has remained relatively unchanged in the brand's lineup for the past 45 years. Built like a tank, complete with an armour shrouded case, this tool-tastic watch is more than ready to tackle your next adventure, whether that be exploring the depths of the Pacific or just the daily rigors of desk work.
