This watch wad laying around in a drawer at my dads, but I can't figure out what the reference/model no is. It's a manual wind from the 70s or earlier. The (intergrated, soldered on actually) mesh strap and case are silver, according to my dad. He used to be a silver smith, so I'll take his word for it, even though I think it's an unusual material for watches (oxidation prone as fuck).

It actually runs on time (wound it, and it kept time for the few hours I was there) even though I suspect it has never been serviced or repaired.

Besides the 'incabloc 17 rubis' referring to the anti-shock & jewels theres nothing on the dial apart from the 'Safira' brand.

Anyone have any idea what this is, and if it's rare? I'd like to get one if they're somewhat reachable.
