A vintage automatic Mirexal from the ca. 1970's equiped with a ETA 2878 caliber displaying French / German day date calendar and a nice kind of old school strap.
Info about the specs of the ETA 2878; here.
Mirexal was established in 1968 by the Swiss retail company Migros. Migros wanted to offer high-quality watches for relatively low prices. Mondaine, the famous railway clock manufacturer, and Rotary Watch Co. used to produce the watches under the brand name. These watches were only sold in Switzerland 🇨🇭. Since 1983 Mirexal watches are not sold in Migros anymore.
