I gained those as part of a giant team of watch strap parts. The bag was once marked AP RO which I suppose is Audemars Piguet Royal Oak. Please take a look at the pictures to confirm. The (*2*) gold link between the strap links is in contrast to any I’ve noticed for Royal Oak. The gold links take a look at at 18K with an digital tester. You get all 3 equivalent width lengths with the 4 unfastened gold links to glue the items.
