NEWS: Imagine finding this in your pocket – Longines discover their oldest watch to date
Without any doubt, vintage Longines watches offer by far the best value to be found in the collectible horology field. The actual values of the two cars will vary as they become older, but the Ferrari will always keep its relative position as more sought after and more valuable than the Ford Fiesta. Longines is the exception to this almost universal rule.
Two serial numbers were required, one being the manufacturer’s number, and Dirty Dozen Omega Longines Grana IWC Grana RAF WW2 WATCH XCHANGE.
There are few brands that take as much pride in their heritage as Longines. Not surprising, really, when you consider that the winged hourglass brand pioneered the way for the reissue. In fact, the Saint-Imier manufacturer is so proud of their history that their own museum is home to more than 10, historic pieces, while the brand also routinely holds competitions around the world in search of their oldest watches.
A big year for Longines, was not only the same year that Longines began manufacturing their components under a single roof in their brand-new factory in the long meadows that the brand is named for, but also the year they began consecutively numbering the watches they produced. Typical of the watches that Longines produced at the time, a winged hourglass is engraved both on the movement and inside its cover, while a floral decoration and two blank crests adorn the front.
The overall splendid condition of the watch, as well as its still properly functioning mechanically wound-up movement, proved to be a major find for the historic manufacturer of timepieces.
