Here's something I'd never seen before: a co-branded Heuer 510.502 (the olive drab one) with both Heuer and Tourneau on the dial.

The Heuer shield is much smaller than usual to accommodate for the jeweller's name. I do remember other L5100-powered private label specimens (mainly Tourneau and Lederer), and notably Chuck Maddox used to own one by Tourneau - but all the others I have seen only had the private label on the dial, this is a novelty to me.
Now the boring stuff: not connected to the seller, not interested in the sale or purchase etc. - yet a very nice watch.
What do others think?
Cheers,
Fabrizio
