Vintage Tissot Sideral Automatic

Vintage Tissot Sideral Automatic. Ref. 40702. Fiberglass case. 39 mm. Blue dial.

A genuine vintage Tissot Sideral, ref. 40702, produced in the early to mid 1970s. The Sideral was Tissot's landmark model of the era, one of the world's first watches to use a fiberglass case, paired with a stainless steel bezel ring. It is lightweight, distinctive and increasingly hard to find in good condition today.

Case and dial 39 mm fiberglass monobloc case with a brushed stainless steel bezel. Deep blue sunburst dial with applied luminous hour markers, the "TISSOT SWISS" logo and the "SIDERAL AUTOMATIC" signature. Date window at 3 o'clock, with a contrasting orange central seconds hand for a clean, sporty look. There are some light scratches on the dial and light marks on the hands, consistent with honest age and wear.

Movement Swiss automatic (self-winding) movement, recently serviced by a professional watchmaker and holding good time. The date change function works correctly.

Case back Original fitted case back stamped TISSOT SWISS, FIBERGLASS. No engraving or personalisation present.

Strap Fitted with a period accurate Hirsch strap in a lizard skin style finish. The type and material cannot be confirmed with certainty, so it is not represented as genuine lizard, but it presents as one of Hirsch's premium lines and suits the watch well.

Condition Recently serviced and running well. The dial shows light scratches and the hands show light marks, otherwise a solid, honest example.

Why it is special A genuine slice of 1970s watchmaking innovation. The fiberglass case was revolutionary for its time and makes the Sideral a real conversation piece next to the more common steel cased vintage divers and dress watches. A strong choice for a collector looking for something a bit different.
