I want to identify my great-grandfathers watch

Nice. Not sure if band is original and just an added item some retailers have on hand to add to watches for more money. No Omega markings

Hands are not original. Both look like the tips have been trimmed and hour hand does not match the minute. Look at the upside down image. Tail of the hour hand is a different design. Rounded end then pointed. Minute tapered

yes, that could happen. Its not a water resistant watch.

Yea even when new, this is a watch you wouldn't really want to get wet. Decent daily-wear trustworthy water resistance didn't start to really happen until the 1960's.

I am not sure either it was kept on a safe for about 50 years because Brazil was too dangerous to use such a a piece, but here where I live it's ok to wear it
