The most sought after bracelet by vintage Speedmaster collectors is undoubtedly the 1450. It’s been called the “Holy Grail” of all Omega bracelets, and once you try it on you understand why. And of course we all know that I made the US1450 so that no one has to go into debt to own one.

But what if it also looks amazing on the Seamaster!? Well, it does!! I introduce to you the US1450 for the modern Seamaster. It was made to fit the latest release (date-window 6:00) and if it fits any others beyond that, it’s news to me. If I hear anything I will be sure to update this listing. Take a look at the pictures and decide for yourself. Is this awesome or what?

• 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.
