Full details below taken from Uncle Straps Website

The 1479 was originally released on some Speedmaster models up until about 1996, and can be found in a similar form on the modern Reduced models. I released it for the Speedmaster and heard from a bunch of my nephews that I should make it for the Seamaster also. Well, why not?

• Wondering if this product will work with your watch? I do my best to outline compatibility details here so you can ensure a good match.

  For bracelets, some of the compatible models listed are submitted from my customers, and therefore I can’t guarantee the fit will be perfect.

  Occasionally these matches require some light modifications to fit correctly. I’ve outlined these steps over on the Bracelet Mods, Tips & Tricks page.
