1940’s LEONIDAS SA Swiss [pre-Heuer] Vintage ATP Military Watch – FHF Cal. 186


Out of stock

Professionally restored and fully serviced in-house here at the Localtime Spa, this is a gents vintage ATP (Army Trade Pattern) military broad arrow watch by Leonidas SA, with a 15j FHF Cal. 186 movement, from the early 1940’s. ATP-issued watches are the true British military watch of WW2 as the later WWW (dirty dozen) were not issued until 1943.

The case [which is correctly marked 1018 between the lugs and with the broad arrow, ATP and serial number #113572 on the caseback] has been professionally cleaned [not polished] and the movement fully serviced. The watch has also received a new, correct plexi-glass and the sector dial and hands have been lightly cleaned. Surely not a safe queen, but an honest and fully authentic survivor from that glorious period. We have made many photos of this timepiece, a scan of Konrad Knirim’s ‘British Military Timepieces’ book and some macro close-up shots we took just for fun. It is wearing a NOS ‘Regimental’ NATO from the 1950’s [also sold separately under eBay item number 202365816256].

As with all the watches we service in-house here at the Localtime Spa, the BIN price includes a 6-month written warrantee from the date of purchase. Feel free to ask any questions you might have.

Important Note On Condition: 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 include a written warrantee with my buy it now price and I always describe what I have changed, if anything, on the watch.

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.

Extra: Check out these NOS ‘Regimental’ straps! I bought these straps from a watchmaker whose father was the watchmaker for the British Garrison here in Cyprus during the 1950’s. They are NOS and in excellent condition. Unlike their modern cousins, they are a bit shorter [23cm including the buckle] so on most wrists there is no need to ‘fold the tail’. Instead of metal keepers, they have one wide keeper. Feel free to contact me for whatever questions you might have. You can see them in the last photo here and they can be purchased separately from my eBay store under eBay item number 202365816256.
