Bas van Dorp emailed me a picture of his Seiko Monster. He wore it during his snowboard trip. As you can see, this Seiko Monster is like the Speedmaster Professional with NASA astronauts, worn on top of the (ski) jacket! The large orange dial makes it very easy to read while being in full action!

Seiko model: SKX781 K3, a.k.a. Seiko Monster, caliber 7S26 (automatic movement with day-date feature). Water resistant to 200 meters (660 ft). Stainless steel case with a diameter of 41mm (height: 12mm). Just google on ‘Seiko Monster’ and you will find plenty of online dealers who sell this watch for a very reasonable price. The ski jacket is a Lowe Alpine and the gloves are by Ziener.

  • Nice pic. 😉

    OM’s are cool – however, I don’t see the Speedmaster resemblance. I have a Seiko dive watch and a Speedmaster – very, very different IMHO. Its difficult to tell from the photo if the OM is on a Velcro strap – perhaps that’s the similarity? -spc

    There is no similarity between these watches 🙂 Except that they can be worn on top of your jacket 🙂

    The OM in the picture is on the stock Seiko rubber strap. Yes both wathces are completely different, but they’re both worn over the suit when in use.

    Actually, this watch is not really big. I owned a citizen diver pro (1000 meter) with automatic winding and it is about 53 mm wide….LOOOL
