Our Seiko 62MAS homage is built on the Crystal Times CT710 – SKX007 to MM Conversion Case, making all kinds of customization possible. The iconic Seiko 62MAS dive watches changed the game when they were introduced by Seiko in 1965.
We've outfitted ours to the nines with a genuine OEM Seiko MarineMaster dial and handsets, which feature outrageous lume that lasts for days and makes you wonder why Seiko is holding back on us fans of the SRPD/SKX lines. Surrounding the dial is a polished stainless steel Seiko SKX007 chapter ring surrounded by modern Seiko SKX007 LX-brushed style bezel. The lumed flat classic sapphire bezel insert finishes off the look to create something unique but true to the spirit of the original 62MAS.
Our friends at Hodinkee note that the nickname "62MAS" originates from a mashup of the product reference number and complications. The 62 refers to the first two digits of the reference number, and the MAS is derived, somewhat mysteriously, from autoMAtic Selfdater. The quick-set date was a breakthrough at the time. Today we see design elements of the 62MAS in other Seiko dive watches over the years. This version is set atop a rugged, handcrafted-in-the-USA black sailcloth strap with white stitching and stainless hardware.
Because this case is designed to fit SKX007 parts, which are much more widely available than other Seiko divers, the look is much beefier than the original but sits true-to-form on the wrist. The 20mm lug width pulls the poles of the case to a narrower point than what the eye is accustomed to seeing with modern SKX models, which can be a bit jarring. Off the wrist, the watch looks exceptionally overbuilt and gangly from the side, but on the wrist it's a different story: an instant classic.
