Longines Master Collection 50,000,000th

With this unique timepiece, Swiss watch brand Longines celebrates its 50,000,000th timepiece.

The 50,000,000th Longines watch will be a unique piece from The Longines Master Collection, the worthy heir to the brand’s know-how, amassed through combined research into exacting technology and timeless elegance. The timepiece will add to the Longines Museum’s considerable historical collection, housed within the company’s walls in Saint-Imier.

Every Longines timepiece has its own unique serial number, initially recorded in the workshop books until 1969, then on microfiches during the 1970s and 1980s, before the advent of the digital age. All watches can therefore be identified down the decades and have their own individual identity. To preserve this historical legacy, Longines benefits from a one-of-a-kind database, the Longines Electronic Archives (LEA), which bring together all the existing archives concerning each serial number. Longines can therefore quickly and accurately inform clients and brand enthusiasts on each of the 50 million timepieces produced to date.

While this complete traceability simplifies the authentication of Longines pieces, it also makes it possible to accurately track the development of production. In 2018, the winged hourglass brand therefore exceeded 50 million watches produced – a true testament to its longevity and legitimacy. This constitutes another historic landmark for Longines, which has created a unique piece with the serial number 50,000,000 for the occasion.

The timepiece, issued from The Longines Master Collection, is intended to be iconic of the brand’s rich heritage and a preview of a new model available soon. Combining classic elegance and excellence, this model houses the new and exclusive L897 automatic calibre within a 40 mm-diameter rose gold case while offering a 64-hour power reserve and displaying an annual calendar at 3 o’clock. The hours, minutes and seconds move with the blued-steel hands that stand out against a silvered dial stamped with a barleycorn motif. A commemorative inscription adorns the timepiece’s transparent case back, which reveals the intricate workings of the movement.
