Extremely rare Bore Sport vintage watch for renovation or parts

Vintage Bore Sport watch with a mechanical movement. The case is made of stainless steel. The watch is being sold as is, for renovation or spare parts.

Case size 28-29mm.

This is highly collectible timepiece. Rare to extremely rare. Please look for Borel's history and role in the horlogerie.

It looks like it is, but
- in my opinion, crystal can be polished
- stainless steel case is intact
- it runs at least in some extent (last photo has been taken some 35-40 minutes later and it ran this time).

Crown is missing. You cannot move hands. Stem condition unknown. At least dirty.

Will be sent by parcel and tracking.

I listed it "buy it now" and the price is negotiable if you have clear and supported arguments. I am selling it now, but my watchmaker is also ready to start full overhaul.
