Don't miss the next drop
The Tissot Seastar line is, in our opinion, one of the most quietly rewarding corners of mid-century Swiss watchmaking, and this late-1960s reference TR 3802 is a wonderfully honest example of why. Tissot founded itself in Le Locle in 1853, spent over a century building a reputation for serious horology at sensible money, and during the 1950s introduced the Seastar nameplate to span everything from purpose-built tool divers to graceful three-handers like the one we have here. To us the dressier Seastars are the most characterful chapter of that story, capturing that mid-century instinct for a watch that slipped discreetly under a shirt cuff and still felt special on the wrist.
Powering this Tissot Seastar is the manual-wind caliber 781, from the brand’s celebrated 78x family. Visible through our movement shots is the warm copper-toned bridge finish that ages so beautifully on these calibers, the caliber number 781 crisply engraved on the lower bridge, and the Tissot script signature still legible on the upper bridge. The 78x series sat at the heart of Tissot’s everyday dress catalog through the 1960s and into the 1970s, and it earned its reputation honestly: thoughtful architecture, reliable performance, and a finish that punched well above the price bracket. Ours runs strong and presents with that genuinely warm copper hue across the bridges that collectors specifically hunt for in this family.
The case combines a gold-plated bezel and lugs with a stainless steel screw-down back, exactly as confirmed by the outer caseback stamping that reads BASE METAL BEZEL ST. STEEL BACK. Lift that back and the inner caseback is clearly stamped TR 3802, locking in the reference. The case measures 32mm across with a 36mm lug-to-lug and 18mm lug width, slipping under a cuff with no resistance whatsoever. The faceted lugs retain their original geometry and the gold plating holds up handsomely across the bezel and lug tops, with the gentlest wear visible at the very corners where decades of cuff contact have softened the plating. The signed Tissot crown is still in place and still wears its interlocking T logo on the end, which is one of those small original-component wins that we always love to see survive.
The dial is genuinely the headline feature. It presents in a clean off-white that has settled into a warm cream with age, the matte surface playing beautifully against applied gilt baton hour markers and a black-printed hash-mark minute track around the perimeter. The slim faceted gilt hour and minute hands carry the same warm tone, joined by a slender gilt central seconds, and the printed Tissot signature with its flanking-bar T logo at twelve and the SEASTAR script below center are crisp and confident. There is very fine spotting visible only under macro inspection, which to us reads as honest mid-century character rather than anything to apologize for. Every printed element and every applied marker is factory-original.
We have paired this vintage Tissot Seastar with one of our tan OTTUHR leather straps in textured calfskin, finished with cream contrast stitching, which pulls the warmth out of the gold-plated case and complements the cream dial without competing with it. The 18mm lug width opens up the full range of OTTUHR strap options, but honestly this combination is exactly how we think a watch like this is meant to wear, equal parts vintage charm and quiet everyday wearability.
Serviced in-house at OTTUHR and backed by our two-year mechanical warranty. For the collector who wants an honest mid-century Swiss dress watch with a properly finished manual-wind movement, a confirmed reference, and the kind of dial that simply does not get printed this way anymore, this Tissot Seastar is, to us, a genuinely compelling proposition.
