I have an Alpha Speedmaster hommage bracelet in SS. No manufacturers markings on it.
Nice and chunky and heavy too its used one week only then put in a drawer I found I'm not a bracelet person.
Looks great on any Speedy lookalike with 20mm or the original Omega itself.
Sized to my wrist but Will come with original spare links, pins, (and pin extractor if you don't already have one, depending what you trade for)
