Tissot PR516GL – An all-original sports watch from the mid-1970s, with integrated bracelet, in absolutely pristine condition. A huge hunk of steel, looks to be unpolished with original brushing. A few years ago Tissot re-released this as part of its effort to revive its sports watches from the 1970s, and you can see why—a more exciting alternative to the PRX, then and now. Automatic movement working perfectly as does semi-quickset day/date. Bracelet currently fits my 7.25’’ wrist with several holes to move up or down. Measures 36.5/38mm with crown x 37mm lug to lug. **$350 obo** Wittnauer “4000” Skin Diver– Excellent condition skin-diver from Wittnauer, ca. late 1960s. Also all original, manual winding cal. C11KS is working perfectly including semi-quickset date. Hodinkee, Analog/Shift, etc. have discovered these in the last few years and you can compare this one to their examples, for a lot less. Measures 38/40mm with crown x 47mm lug to lug. A strap monster that will come on the 19mm vintage pigskin strap in pictures. **$500 obo** Longines – Black-dialed Longines from the 1950s with famed cal. 19a automatic movement. I have the twin in white dial and a black dialed Conquest, so I’ve decided to part. The watch winds, sets, and runs great. The black dial is untouched and has some patina visible in the pictures (mostly around some of the hour markers). The only non-original piece is the crown which has the Favre-Leuba logo. Charming case measures 33.5/35mm with crown x 42mm lug to lug. The watch will come on the period-correct 18mm pigskin strap in pictures. **$325 obo** Eterna Kontiki 10 – Beautiful lines and slate dial Kontiki 10, from the early 1970s. In excellent cosmetic shape and appears to have never been polished. Everything is original and signed including the signed crystal. The ETA automatic movement is keeping excellent time and quick set date (pump action) works perfectly. Beefy case measures 35.5/38mm with crown x 40mm lug to lug. The 18mm mesh strap is aftermarket but period correct and included in sale. **$275 obo** All watches ship free from Connecticut to anywhere in USA. Happy to ship overseas for $20 extra.
