1951 LONGINES (Swiss) Ref. 5577 Vintage Dress Watch Cal. 27.M – Extract From Archives


1 in stock

Professionally inspected in-house here at Localtime, this is a great example of a classy Ref. 5577 dress watch by Longines (Swiss).

The matte steel case (33.50mm or 35mm counting the crown at 3h) has been cleaned (not polished) and the manual-wind Longines Cal. 27.M movement inspected. A stunning watch that oozes class whichever angle you look at it from, this classic dress watch is wearing one of my own Tejus-lizard grain leather straps in brown (which comes in many colours and sizes and can be purchased separately from our store), that I think compliments the champagne dial, gold hands and applied numerals, very nicely. Extract from the Longines Archives is included. 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 we handle inhouse, the listed buy-it-now price includes a 6-month written warranty from the time of purchase. Do not hesitate to contact us for any further information you might need.

Extra: Try my Localtime Tejus lizard-texture Italian leather straps! I have found these straps to be very comfortable and a great match especially for dress watches that will combine well with this style of straps. They come in 5 sizes (16-18-20-22-24mm), 11 colours and have colour-matching stitching. Their length is approximately 85mm on the buckle end and 115mm on the tail end; so not short but not too long either. Please note that silver and gold refers to the buckle colour and not the material. They have two keepers, one of them is fixed and the other one is floating, for a better fit and comfort. I sell these straps separately in my store and you can also see them in the last photo here. 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 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.
