Wonderful Early 1950’s MIDO (Swiss) Multifort Extra-Flat Ref. 7511 Watch, 15j Cal. 1200B Sweep Seconds


1 in stock

An early and 100% original 1950’s Mido (Swiss) Multifort Extra-Flat Ref. 7511 with a 15j Mido Cal. 1200B with sweep seconds, this stunning watch has been professionally inspected in-house by Localtime.

The classy Francois Borgel unpolished steel case measures 34mm or 36mm including the half-recessed crown at 3h. Lug-to-lug it is 41mm long and it takes 16mm straps at the lugs. The dial and hands are just breathtaking! It is wearing a same-period NOS pig-skin strap in black. Really nothing to mention, this is a wonderful example all around.

As with all the watches we handle inhouse, the listed buy-it-now price includes a 3-month written warranty from the time of purchase. Do not hesitate to contact us for any further information you might need.

Extra: Try our Localtime line of military straps shown in the last photo below, listed separately in my store.

Important Note: Sometimes I am asked what I exactly mean with ‘professionally inspected by Localtime’. Here is my theory on vintage watches: as a purveyor of vintage watches, my effort is to always do only what is needed to the watch. I do not buy ‘junk’ watches to resell. I am choosy with my purchases and always sell watches that are, to my knowledge, authentic and in good condition. I first inspect the watch, both visually (cosmetically) and then mechanically. If I judge that the watch is not yet in need of a full service then I do not put the watch through a service which, by the way, entails a lot of risks too. Instead, I give it what I call my ‘Spa’ treatment which will include a cleaning, changing of gaskets, oiling, lubricating and mechanical testing. If the plexi is heavily scratched or discoloured and it can not be cleaned, I change it. If the crown is wrong or worn, I also change it. Now, if the watch is in need of a full service, then my ‘professionally inspected’ description becomes ‘professionally serviced’. In both cases, I mention what has been changed (if anything) on the watch and I include a written warranty with my listed price.

Important Note On Straps/Bracelets: The straps I use on my watches (leather, canvas, suede, rubber) are always brand new, unless otherwise mentioned and, in most cases, I also sell them separately in my store, in different colours and sizes. In the case of metal bracelets, if the watch is NOS, the bracelet is also unused. If the watch is pre-owned with its original bracelet, then the bracelet is also pre-owned, unless otherwise mentioned. Either way, if in doubt, please ask.
