Remeber my very first watch in late 70s. It was beautifully crafted, Swiss handmade Omikron.
I exchanged it for gold-plated Citizen, blingy. kitchy early 80s model, but still regret.
Anyone with Omikron these days? They are quite low cost on Ebay.
I've got one but unfortunately in non-working condition, I'm guessing they were somewhat common in SFRJ considering the picture of the one you linked and that mine was bought in Bosnia.
