TISSOT – one of the grand swiss brands that still exists. Founded in Le Locle, Switzerland in 1853 by the locals Charles-Félicien Tissot and his son Charles-Émile Tissot they started as an assembler of parts. With a contact to the Czar of Russia made by the son in 1858 they sold pocket watches in the whole Empire through the next decades. The kids Paul and Marie were continued the company later. Around 1925 Tissot did a commercial partnership with Omega in which Société Suisse pour l’Industrie Horlogère (SSIH) was created. 50 Years later the SSIH merged with Allgemeine Schweizerische Uhrenindustrie AG (ASUAG) in 1985 into the Swatch Group.

Back to the Yachtings: some of the 60s/70s Tissots have blue segments – perfect for using measuring the time of a regatta start.

Tissot started with blue segments on the Siderals in the late 60s, fiberglass case, dial and bezel and bullhead case design. Then the 2- and 3 compaxes and Regatta watches with Lemania 1341 and 1345 movement were launched in the 70s.

One gets known by the research of our friend GVM (Gianvittorio Molteni) who discover the watch on one of the rare racedriver woman, Liane Engeman, well-known race driver in the late 1960s from the Netherlands. It´s the watch this post is starting with, white dial 3 compax Tissot Seastar.

Starting with the 2- and 3-compax watches with Lemania and Valjoux movements first.

The question “is a blue segment made for yachting?” is definitely answered in some ads, where especially the blue segment in the subdial is “made for yachting and regatta starts”!

Tissot produced these watches with many different dials and cases. Lets try to classify them and let´s differ two groups – the one with Lemania and the one with Valjoux movements. After that we have some with bezel and some without and different case materials. And 2 or 3compax.

You find all in this table.
