Lecoultre S Series Of Serial

Because we are not an Authorized Dealer for Jaeger - LeCoultre, we can not advertise their watches as brand new.

For all intents and purposes, the watches we sell are USED, but are in immaculate - perfect - never sold condition.

We trust these timepieces to be of such high caliber that we warranty all unworn condition watches for a period of 2 years unless it is sold as a used watch, and in that case, you will receive a 1 year warranty.

You CAN NOT expect and WILL NOT receive the factory Jaeger - LeCoultre warranty on any watch we advertise.

We encourage you to call us if you have any questions.

The example below uses information from the American Waltham Watch Company, but that is just an example.

You should consult the serial number table for the specific brand of watch movement you are trying to date by selecting a company from the menu on the left.

Some American watch brands did not use a consistent series of serial numbers, but most of the big manufacturers did.

So to determine when your watch was manufactured, you will need to find where your serial number fits within the range of numbers.

Note that were using the serial number from the watch movement, not from the watch case.

Looking at the table of Waltham serial numbers (see example below), you can see that number 20,900,000 was made in 1917 and 21,800,000 was made in 1918 (marked in red in the table below).

Since your serial number falls between those two numbers, you know that your watch was made in 1917 or 1918.

Cases and watches were often made by different companies and each usually has its own serial number.

You usually have to take the back off the watch case to see the movement serial number which may appear anywhere on the watch movement.

Your movement serial number may not be in exactly the same location as the one in the photo, but you are looking for the serial number that is on the watch mechanism itself.

Be sure to use the table that is specific to YOUR brand of watch when looking up your serial number.
