Olympic Compressor bleu 1973. This is the former watch from my late father.

I know the date of this watch exact because It was won as a price from a local jeweler. That shop is no longer excisting.

This watch have a ETA movement and a Incabloc shock system. It's a Compressor so its total watertight. Back than.

Olympic is a Dutch watch brand, still live's on to day.
