Tissot Sonorous T12

IBM introduces the floppy disk

1970 Tissot Sonorous ref. T12 40512 Alarm, movement cal. AS 1930, stainless steel 44mm. compressor case, inner rotating bezel, this is one of the rarest T-12 made in the 60/70’s and a great option for a big vintage alarm. It also features interesting, inwardly angled and applied hour markers and internal bezel that further assist in making the watch seem smaller.

Tissot was founded in 1853 in Switzerland offering the first mass-produced pocket watch in that year. They went on to introduce a number of firsts: first anti-magnetic watch, first watch made of stone, wood and plastic.

Interestingly, Tissot merged with Omega back in 1930. Lemania, the movement maker joined the group 2 years later and became the chronograph movement maker for the brands. Having a captive chronograph maker enabled both Omega and Tissot to become official timing partners for many events such as the Olympics, Formula 1 and other sporting events. Tissot and Omega used a lot of similar or even same movements over the years. At times, Omega used a slightly more advanced version or one with more decoration – think of it like VW and Audi. Omega, Longines and Lemania have been under the Swatch Group since 1983.
