Longines Serial Numbers Complete Guide

Longines Serial Numbers Complete Guide

Longines is one of the oldest Swiss watch brands in the world. Founded in 1832, Longines has achieved and done a lot over the course of its history. From winning the Grand Prix at the Universal Exhibition in Paris in 1900 to being the official timekeeper for Formula 1 for 10 years, and much more in between.

The vast majority of watches are equipped with serial numbers. This is no exception for Longines watches.

The serial number is unique to every single watch and is used for a number of different reasons.

Primarily, the serial number is used to help the manufacturer to keep track of every single watch that leaves the factory. This allows them to get detailed information about the watches.

An example of such information is dating the production time of the watch. With the help of the serial number, you can date your Longines watch, and we will go into detail about how you can do that further on.

Longines serial numbers

Few manufacturers keep as well-recorded records about their watches as Longines. In fact, Longines has recorded every single serial number of its watches since 1867. Safe to say that is quite a substantial record. Using its record, Longines can provide first-class and detailed information about the timepieces that have left the factory. What is even more interesting (and something we have Longines to thank for), is that Longines is happy to share this information with the public.

Companies like Rolex naturally have a well-recorded database of their serial numbers, but do not disclose this information to the public as Longines does. We will go more into detail about this further on.

The serial number consists of 5 to 8 digits.

Longines serial numbers can normally be found engraved on the case back. Most often, the number is engraved on the outside of the case back, but in some cases, it may be engraved on the inside, which means you need to remove the case back in order to access it. The serial number may also be engraved on the movement.

To date your Longines watch, you can either take help from the serial number list below or identify the age and production year of your vintage Longines watch by ordering a certificate of authenticity or extract from the archives directly from Longines.

  1. May I know how often do I need to send my Longines for service L678.2

    1. Hi,
      In general, most watches should be serviced between 3-5 years. The most important indicator is its accuracy. If it is running well and accurate, then it is an indication that it is not in acute need of a service. If it is running poorly with poor accuracy, then it is in need of a service.

      Kind regards.
