I recently stumbled on two very badly listed auctions on eBay, and they might be of interest for some of you.
The first one is for an Auricoste Spirotechnique (with the usual misspell "Avricoste") and for now the price is not too astronomical yet:

And while browsing the seller's other items, I stumbled upon this one which, in my opinion, is even more interesting:

From the looks of it, this Beuchat was an issued watch with the French Navy, as evidenced by the "MN" engraving (for Marine Nationale) on the caseback. According to the listing, the crown doesn't screw down anymore, but that's a minor fault for a military watch at this price point!
