Longines Age Determination

One of the oldest Watch Brands in our range is LONGINES. Founded in 1832, the brand became especially famous for its distinctive Pilot watches and sporty Chronographs. The world-famous Pilot watch Longines Lindbergh, for example, was named after the US-American pilot Charles Lindbergh, who in 1927 crossed the Atlantic alone in a nonstop flight. He wore a Longines Pilot watch strapped to his upper arm.

In addition, numerous models have been developed over the years that still have a firm name among collectors and watch enthusiasts today. These models include the Dolce Vita, the Grande Vintesse and the Hydro Conquest.

Determining the age of Longines watches is an important aspect for collectors and it is sometimes very tedious to sift through the various websites on the internet to find the appropriate information. We have dealt with this topic and compiled some serial and caliber numbers to enable you to determine the age of your watch at a glance.

Longines Serial Numbers

The serial number or case number is a consecutive number that is assigned only once and thus uniquely identifies a watch. The location of the serial number varies depending on the age of the watch.
The serial number can be found in the following places:

– outside on the back of the watch case (for newer wristwatches)
– inside on the case back
– inside the protective cover (for pocket watches)
– on the Movement

Here is an overview of the serial numbers:

Longines Calibers

The caliber stands as a manufacturer code for mechanical movements. Longines calibers are sometimes given as a sequence of numbers and sometimes as combinations of letters and numbers. The caliber means a specific production unit for the manufacturer, for example a movement with a stopwatch function and a Power Reserve of X hours.

A highlight of the brand dates back to 1878. In this year, the first Longines Chronograph with caliber 20H was developed. The first caliber for a wristwatch of the brand came onto the market in 1913. It bore the number 13.33Z and was so renowned that it was used again in 2012. From 1916, rectangular and oval calibers were produced in series, which still today make up the distinctive charm of, for example, the model Dolce Vita .
