If you like the look of the new 3861 Speedmaster bracelet this might scratch that itch. The 1479 was actually released on some Speedmaster models up until about 1996, and can be found in a similar form on the modern Reduced models. I decided this one needs to be made available to a wider audience. Who doesn’t like options, am I right?

Designed to fit: 20mm Omega Speedmaster

PLEASE NOTE: The 20mm US1479 will not fit the new Speedmaster 3861.  We cannot guarantee fit with special edition Speedmaster’s.

• 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.
