2012 Longines Flagship D&D Automatic Watch Ref. L4.799.4.12.1 – 25j Cal. L636


Out of stock

Professionally inspected in-house here at Localtime, this is a great example of a classy Flagship Ref. L4.799.4.12.1 dress watch by Longines [Swiss].

The steel case [36mm or 38mm counting the logoed crown at 3h] has been cleaned [not polished!] and the Longines D&D Cal. L636 movement inspected. A stunning watch that oozes class whichever angle you look at it from, this classic dress watch is wearing its original leather strap and buckle, that we think compliments the white dial, silver hands and numerals/logo, very nicely. It also has its certificate from Longine’s Heritage Department, that I will, of course, include with the watch. I have included many photos of this beautiful timepiece, including some macro close-up shots I took just for fun.

As with all the watches I handle in-house here at Localtime, the BIN price includes a 6-month written warrantee from the date of purchase. Feel free to ask me for whatever clarifications you might need.

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.

Extra: Try my Localtime Cordura Canvas straps! Very excited about this new line of straps that I decided to carry. High quality Cordura canvas in 8 colours [black, blue, brown, khaki, green, orange, red and yellow] and 4 sizes [18-20-22-24mm with a 2mm tapering] with ‘Lorica’ waterproof liner, Italian-made. The length is 90mm including the steel buckle by 120mm on the tail side. Thickness-wise, they start at approximately 4mm and thin down to 3mm. They have two ring-holders: a fixed one and a semi-floating one with fabric ‘belt’ to hold the tail, for a safer and more comfortable fit. They will be a very welcomed upgrade to the either ‘naked’ canvas [no liner] or the calf-lined canvas which are considered of a ‘simpler’ quality. A pair of good quality spring bars will accompany each strap. Feel free to contact me for whatever questions you might have. I sell these separately in my eBay store under eBay item number 401496392712.
