I like it with this watch, the gold flecks perfectly match the 18kt gold case Probably mostly a man made product and I believe durable, no cracks or wear at stress points
Such a wonderful piece and a nice size, considering the era. I wish mine were this good. I've got a very rough example. Patina'ed dial is being kind, plus I am missing the 45-min register hand. So far, it's been tough to locate one. Mine's on an authentic, vintage Tropic strap, which is kinda cool.
