In our opinion, the early-1970s Tissot Seastar Automatic is one of the most genuinely undervalued corners of vintage Swiss watch collecting, and this particular example pulls every lever we look for. A factory-original silver sunburst dial that has aged in a way no other Seastar dial will ever match, a warm gold-toned cushion case with the curved lug architecture Tissot did so handsomely in this period, the Tissot in-house caliber 786-2 ticking underneath, and a caseback engraving that locks the watch into a real human story. To us, this is the kind of vintage Tissot Seastar Automatic that experienced collectors quietly chase.
Tissot has always occupied a wonderfully interesting position in the Swiss hierarchy. Founded in Le Locle in 1853 by Charles-Felicien Tissot and his son Charles-Emile, the house spent more than a century building a reputation for delivering serious watchmaking at prices that consistently undercut peers charging twice as much. The Seastar line emerged in the late 1950s and quickly became Tissot’s most enduring family, spanning everything from quietly dressy automatics to capable tool watches. By the early 1970s, the Seastar Automatic was Tissot’s daily-driver workhorse, and the ref. 44660 sits squarely in the dress-leaning side of that family, a clean and confident expression of what Tissot did best when the rest of the industry was busy chasing tonneau cases and rainbow dials.
Inside this Seastar beats the Tissot caliber 786-2, a 25-jewel automatic with center seconds and date that traces directly back to Tissot’s in-house movement design language of the late 1960s. The 786-2 is the date-bearing successor to the foundational 784 architecture, and across the dress-leaning Seastar Automatics of the early 1970s it was the caliber Tissot reached for first. Through the open caseback we have for photography, the rose gold-toned rotor sits dead center, the bridges are visibly signed Tissot, and the whole layout reads as the kind of straightforward Swiss automatic any vintage watchmaker can service without drama. It is honest, it is well-proven, and it runs.
The case is where the visual personality of this Seastar lives. A cushion silhouette measuring 35.5mm across, 40mm lug to lug, with 18mm lug spacing, executed in a gold-tone outer case mated to a stainless steel caseback in the two-piece construction Tissot used widely on this reference. The lugs curve down and slightly inward in a softly twisted profile that catches light beautifully and gives the watch a much more interesting wrist presence than a flat-lug dress watch of the same dimensions. The case sides show honest wear at the high points, with some softening of the brushed finish where the watch has clearly been worn rather than locked away. The Tissot-signed crown sits at three with the embossed T emblem still clearly readable. The outer caseback shows the wonderfully unusual decagonal star-cut edge that Tissot used on this generation of Seastar screw-back cases, and the inner caseback carries the Tissot shield, the French language “FOND ACIER INOXYDABLE” stamping, and the ref. 44660-1X case designation that confirms exactly what we are looking at.
The dial is the moment. A factory-original silver sunburst surface that throws long radial reflections as the case tilts, dressed with applied gold baton hour markers running the full circumference and gold dauphine-style hands with a central channel for what was once tritium lume. The “T SWISS MADE T” designation at the very bottom of the dial confirms the tritium era. The Tissot wordmark sits in black print just below the Tissot shield emblem at twelve, with “AUTOMATIC” and the Seastar script under center, and a small starburst emblem between Seastar and the swiss-made line. Then there is the speckle. Scattered across the dial surface and concentrated most heavily near the center, a fine dusting of orange-red particulate sits across the silver sunburst. In our opinion this is degraded tritium lume that has slowly released from the hand undersides over decades of mechanical motion, settling on the dial like very fine rust-colored pollen. The hand lume itself reads as the expected dark-greenish degraded patina you see on tritium that has aged in place. It is entirely organic, entirely irreversible, and to us it gives this Seastar a dial character that no factory finish will ever replicate. The applied gold markers remain crisp, the date aperture at three is clean with a white wheel and crisp black numerals, and the overall composition is genuinely beautiful.
The caseback is the part that makes this watch personal. Engraved in clean block letters across the steel: “HARRY F. RAU, 21 YEARS SERVICE, BELL TRANSIT CO.” This was a presentation piece, a reward marking more than two decades of dedicated work. There is something quietly compelling about a vintage Tissot Seastar that carries this kind of provenance. It was not bought on a whim or tucked into a drawer. It was earned, and the patina across the dial and the soft wear on the case is the visible record of years of subsequent wear by the man whose name it bears.
We have paired this Seastar on a forest green leather strap with white contrast stitching that plays beautifully against the warm gold case, picking up the cool side of the silver dial sunburst and lifting the whole composition into something with real character. Serviced in-house at OTTUHR and backed by our 2-year mechanical warranty, this is a wonderfully complete vintage Tissot Seastar Automatic package, factory-original dial, matching original gold handset, untouched Harry Rau presentation engraving, signed Tissot crown, and the in-house caliber 786-2 doing its honest work underneath. For the collector who values character and provenance over flash, who appreciates a vintage Swiss automatic with a real human story etched into the back, to us this is exactly the kind of Tissot Seastar we love bringing in.
