HowTo – Determine the age of your Jaeger LeCoultre watch

Sometimes you really want to dig into the history of that watch you just found. For some brands you can easily get in contact with the brand and ask for some (free) information from the archive (more on that here). In other cases you just want a quick check on the serialnumber to determine the year that a watch is built. This is especially useful with military watches since these require the watches being built somewhere prior to or during 1914-1918 for the first world war or prior or during 1939 – 1945 for the second world war. I dare to say that most military watches offered on eBay actually are most certainly not.

I recently purchased a copy of Zaf Basha’s “Jaeger LeCoultre”, which is a great resource on JLC as a brand and a rundown of the best movements and watches they made in their rich history. I have quite a few books about watches but this one is by far one of the best and I would like to encourage anyone to find yourself a copy. (ISBN 0615223877)

On this page was a table with serial numbers per year, however I received a friendly request to remove it by it’s copyright holder. However I have permission to provide lookups, so if you want you can an email to with your serial number and I will provide you with the correct year.

If you open up the case of your Jaeger, Jaeger-LeCoultre or LeCoultre wristwatch you can usually find a serial number like in this example below. The 269.000 serial number points to a production year of somewhere around 1943.

I hope this helps you out, please know that these lists are available for a lot of other brands as well. Success!

    1. Hi there friend… i feel comfortable addressing you as such seeing how many people you have helped out, your awesome for that! I myself am in need of your help… the only info i am able to provide would be the markings on the outside as well as pics due to me not having the courage to open the watch myself. Thank you

      1. If you don’t have the appropriate tools and the knowledge to properly open watches then I would like to suggest to ask a proper watchmaker (not a jeweler) to open it up for you. They can also inspect the condition of the watch movement for you. Please know that a properly maintained watch can easily outlive you.

  7. Good call , an actual watchmaker. I do know of a shop that is local to me…. although it is currently closed due to … well anyways , i was hoping you would still help me out? My JLC also has the numbers 146.2.17 on the case as did Stephens. My watch looks like the Master Hometime Aston Martin except these few differences… the faint A.M. logo under the 3 o’clock hour , also lacks the red tip on the watch hands as well as there being just the hour and minute hand with the second being on a seperate dial. My JLC does not appear to have the 975H calibre as does the Master Hometime. Thanks again for the watchmaker tip and any other info you coukd help me with would be much appreciated ..thank you.

  8. Hi, do you have information on dating more recent Jaeger LeCoultre watches, e.g., from the 2000s? Mine is a Master Control Geographic (white gold) with a serial number of 3,073,314 (cal. 929/3)

    1. Sadly not, for modern watches the only way is to request an Archive Extract from Jaeger LeCoultre directly. Which sadly is quite expensive.

  12. Just scrolling through the comments I think you must be an amazingly patient person. I guess it comes from having so much time on your hands (that’s a joke btw). I also have an older LeCoultre that I would like to date, but instead of asking here, I think I’ll send an email with a couple of photos of the watch, as well as the serial and case numbers. Hoping it’s a 72 VJ but I guess I’ll have to wait and see.
