This GP is sooo nice, hard to capture on photos... It's a large steel 'waterproof' tank model from the early 50's in mint, like new condition. I've never seen another so it's very rare and stunningly beautiful. Not the least because of the size (28x40mm incl lugs) but also because of the special case design which actually resembles the much later Heuer Monaco! The original dial is super clean and classy with radium indexes and hands. Movement is Girard Perregaux and working well (no pix as it's better to leave the gasket intact). Complementing this special watch is a new 20mm steel beads of rice period correct bracelet. Overall a super rare, classy, large and unusual high grade waterproof tank watch which will complement any vintage collection!
