Launched in 2000 as an extension of their SKX diving watches range, the Seiko SKX779 and SKX789 soon become extremely popular with those looking for an affordable tool watch. With its distinct look – a toothy bezel, large indices with bright lume, a bezel guard – and bold styling and tough build quality, this watch was soon labelled ‘Monster’ on chat forums and the Orange Monster (SKX789) is probably one of the most distinct divers out there today. The original ran Seiko’s trusty 7S26 movement but in 2015, Seiko updated the Monster with a 4R36 movement.
