Mido was founded in 1918 by Georges Schaeren in Solothurn, Switzerland, and moved its watchmaking operations to Le Locle in the 1930s. The firm built a specialty in automatic movements during the 1930s and 1940s, particularly in water-resistant and shock-resistant cases adapted for professional and sports use. The Multifort (1934) was among the first automatic, anti-magnetic, waterproof wristwatches offered commercially; it is still in production today under the same name, one of the longest-continuing model names in Swiss watchmaking.
The Commander, launched in 1959, introduced Mido's most distinctive technical innovation: a monocoque case with no caseback. The movement was accessed by removing the crystal from the front, eliminating one of the three critical gasketed seals on the watch and improving overall water resistance to a remarkable 200 metres on a dress-size case. The Commander remained in continuous production and became Mido's flagship; the 2019 Commander Chronometer is still built on the same monocoque architecture.
In 1970, Mido was absorbed into General Watch Co. (later part of ASUAG and eventually the Swatch Group). The Swatch Group era positioned Mido as a mid-market mainstream Swiss brand, typically around CHF 1,000-2,500 retail, using ETA movements with Mido modifications including the house's 80-hour power reserve (Cal. 80, a Mido-tuned ETA variant that standard-beat rates down to 21,600 vph to extend reserve from ~42 hours to 80). The 80-hour movement became Mido's core proposition: more power reserve than competitors at the price tier.
Mido's modern collection all carries architectural names. The Multifort (since 1934, referencing the Sydney Harbour Bridge) runs sports and pilot variants. The Commander (since 1959, referencing the Eiffel Tower) is the dress flagship. The Ocean Star (referencing the Statue of Liberty) is the dive watch. The Baroncelli (referencing the Galleria Vittorio Emanuele II in Milan) is the classical dress line. The Rainflower (referencing the Marina Bay Sands in Singapore) is the women's line. Retail runs from CHF 900 (quartz variants) to CHF 3,000 (Commander Chronometer automatic) and CHF 5,000+ for specific chronograph and complicated variants.
