MS-5517 “Sword” (ST-1812)

Item Description

The MS-5517 or “Sword” is part of our MilSub Range or Military Inspired Diving Watches (1950’s-1970’s). Here we have distilled the essence of these classic British Special Boat Squadron (a Special Forces Unit of the Royal Marines) watches. It has the sword hands, the full 60-minute bezel in the classic case with crown guard. A restrained classic. There are 2 designs: MS-5517 Vintage, a closer interpretation of the classic SBS watch; and MS-5517-DO (Date Option)

  • MS-5517 Vintage: No date and full 60-minute bezel insert in ceramic with coloured lumen, mimicking the faded lumen of the original.
  • MS-5517-DO: With date complication, 60-minute bezel insert in ceramic, outer minute track with military (24 hour) markings and raw C3 SuperLumiNova. This is our interpretation of what the MS-5517 should/would be.

I was pretty sure that Dan Fock was a detail dilettante, but it wasn't until I received the OWC MilSub MS-5517 that I was quite assured of it. Let's be clear that the OWC MilSub MS-5517 isn't a perfect watch, but it has some amazing details that only could have come from Dan's perseverance and sheer struggle with his suppliers, who no doubt needed a lot of pushing to get certain things right.
