1971 Mido Multi Star World Time.
I never seen this watch before, never found it any place, if you have any information about it please help me to complete this page sending me an email or just add the information at the forum space.
In 1934, Mido introduced Multifort, a completely revolutionary watch at that time: it was shock-proof and water resistant, besides being antimagnetic. The Multifort was also the first Mido model to have a self-winding movement and this was an achievement in the history of the company. In the same year, Mido introduced watches with unbreakable strings, as well as a new system for waterproof watches. It consisted of using cork to seal the crown: the stem of the crown passes through a tiny cork gasket compressed in a housing, which ensures a seal even if the crown is not fully pushed-in. Franz Linder, Director of Mido, compares this to a bottle of wine that remains sealed even if the cork is half-drawn.
