2011 LONGINES Ref. L2.689.4.51.7 Master Collection Pilot Watch – Longines Cal. 691 With Date


Out of stock

A stunning example of a LONGINES Ref. L2.689.4.51.7 Master Collection Pilot Watch with Longines Cal. 691 all steel pilot/aviator watch in all original condition, that has been professionally inspected by Localtime.

Serial Number #36530774 please its production in 2011 as you can see from the certificate from the Longines heritage Department. The case measures in at 47.50mm or 50mm including the original, screw-in crown at 3h. It is wearing one of my own ‘Sorrento; leather straps, in black. These lovely leather straps come in different colours and sizes and are listed separately in my store, under eBay item number 401614133284. They also come in extra-long sizes.

As with all the watches that are handled by Localtime, the listed price includes a written 6-month written warranty from the date of purchase. Feel free to contact me for whatever questions you might have.

Extra: Try my own Sorrento premium calf leather straps: Wonderful straps, I have found these to be very comfortable and a great match especially for sport watches or larger dress watches and chronograph watches that will combine well with this style of straps. They come in 6 sizes [18-20-22-24-26-28mm], 7 colours and have natural colour stitching. Their length is approximately 90mm on the buckle end [including the steel buckle] and 115mm on the tail end; so not short but not too long either. The black and brown variations also come in an extra-long size of 100/128mm. They are nicely padded, measuring 5mm thick at the lug end and they taper down to 4mm at the tail end. They have two keepers, one of them is fixed and the other one is floating.  A good quality pair of spring bars is included with each strap. Feel free to contact me for whatever questions you might have.

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 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.
