Available now on auction by Second Vintage This 1970 Tissot Seastar is a charming example of robust Swiss engineering from the golden era of mechanical watchmaking. With its classic stainless steel case and manual-wind movement, it represents the honest, utilitarian elegance that defined Tissot's sports models of the period. The watch features a dial that has developed a heavy, uniform patina, often referred to by collectors as "stardust" or "freckling," giving this specific piece a truly unique and distinguished vintage character that cannot be replicated. Brand: Tissot Model: Seastar Reference Number: 41520 Serial Number: 11581387 Movement: Manual Wind Cal. 781-1 Dial: Silver sunburst with heavy uniform patina Case Size: 34 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1970 Condition: Good vintage condition Dial and Hands The dial was originally a silver sunburst finish but has matured to show significant, evenly distributed patina in the form of oxidation speckling across the entire surface. This aging process provides a unique "stardust" effect that adds vintage appeal. It features applied polished baton indices with black inlays and matching baton hands. The tritium lume plots at the outer edge of the markers have aged to a dark tone, consistent with the hands. Case and Crystal The stainless steel case measures 34mm and features straight, sharp lugs that give it a classic profile. The case is in good condition with visible scratches and signs of wear consistent with its age, particularly on the polished bezel and case sides. It retains its original Tissot-signed crown, which is a desirable detail for collectors. The screw-down caseback bears the reference numbers 41520 / 42520-4X on the inside and displays superficial scratches on the exterior brushed finish. Movement Powering the watch is the reliable Tissot Caliber 781-1, a 17-jewel manual wind movement known for its durability. The movement appears clean and free of significant oxidation. Timegrapher testing indicates the watch is running between +10 and +18 seconds per day, which indicates a healthy movement performing well within acceptable vintage tolerances. Strap The watch is fitted with a new black leather strap featuring an alligator-style embossed pattern and a stainless steel buckle. The strap is supple and complements the monochromatic aesthetic of the dial and case. Condition This timepiece is in Good vintage condition. While the case shows expected surface wear and the dial exhibits heavy patina, the structural integrity of the watch is excellent. The movement is clean and running strong. It presents as an honest, unrestored survivor that wears its history proudly. Dimensions The case diameter is 34 mm excluding the crown. The lug-to-lug length ensures a comfortable fit on a variety of wrist sizes, adhering to the classic proportions of 1970s dress-casual watches. Remarks This Tissot Seastar offers a fantastic entry point into vintage collecting for those who appreciate watches with visual character. The specific patina on the dial transforms it from a standard model into a unique piece of art shaped by time. It is a robust daily wearer that combines the reliability of the Tissot 781-1 caliber with a distinctive aesthetic.
