Available is a super cool 60's toolwatch. It's a mint first series Favre-Leuba 'Bivouac' reference 53213 with Altimeter and Barometer from the early 60's. Measuring altitude and air pressure, this was the ideal watch for mountaineers. The thick screwback case features a rotating bezel and houses the manual movement Cal. Peseux 320 / 10032 and on top the barometer mechanism. It measures 40mm excl. the original crown. The original silver dial is in beautiful untouched condition with lovely serif black print. Attached is the original brick style fully signed bracelet. Certainly one of the better examples out there and a super cool watch!
