A serial number is unique to each TAG Heuer timepiece. Serial numbers play a crucial role in demonstrating both authenticity and ownership. IT IS LOCATED ON THE BACK OF YOUR WATCH There are two numbers engraved on the caseback of your watch. In this video we will be discussing where the serial number is on an Arcade 1up machine. Arcade 1Up makes a ton of different models of their arcade games. Locating your Omega serial number. Recent Omega watches usually carry their serial number somewhere on the back but they will be in extremely small laser-etched digits requiring a magnifier to read. Older Omega watches may only have the serial number on the inside of the watch, requiring a jeweler to open it for you.

Finding the Model and Serial Number

Most Seikos have a 'retail' model number that is displayed in the store but not written anywhere on the watch.They also have a 'reference' model number that is written on the case back.This reference model number is a combination of two numbers:

movement caliber
case code

Each of these two numbers are four digits long and they are separated by a hyphen.In the example images the reference model number is highlighted in red.

The other number you will need is the serial number.This is also on the case back and is six digits long.In the example images the serial number is highlighted in blue.Every watch has a unique combination of reference model number plus serial number.


Example #2
6309-576A | 2D5822
Mvmt-Case | Serial

How is the Date Calculated

The first digit of the serial number tells you the last digit of the year the watch was made.Looking at the example images:

for example #1 the year ends in 0
for example #2 the year ends in 2
for example #3 the year ends in 4

You may notice this does not tell us which decade.That is why we also ask for the model number.For many of Seiko's movements we know the first year they were producedand for most movements they were produced for less than 10 years.This helps us narrow down the decade.

Serial Number On Watch Series 2

Using this additional information we can update our three examples:

the 6119 was first made in 1970 so #1 is from 1970 or 1980
the 6309 was made from 1976 to 1987 so #2 is from 1982
the 7S36 was first made in 1996 so #3 is from 2004 or 2014

The second digit of the serial number is also useful. It tells you the month the watch was manufactured.Here are the possible values:

Serial Number On Rolex Watch

The remaining four digits of the serial number indicate the production number for the watch.If your last for digits are 0000 then you have the first watch made for that model reference number.Returning to our examples and using the second digit from the serial number we get the following production dates:

The 6119-8083 061187 was made in June of 1970/1980
The 6309-576A 2D5822 was made in December of 1982
The 7S36-03J0 411082 was made in January of 2014

I know example #3 was not made in 2004 since I bought it new in 2014.


Example #3
7S36-03J0 | 411082

Why Do We Ask for the Case Code

If you were paying close attention you may have noticed we asked for the case code in the form above but we did not mention using it when calculating the date. You can leave that field blank and still findthe date for your watch however if you complete the field we will provide a listing of watches from our Seiko catalogsthat match the movement and case code.

Special Thanks

What you see here is in large part thanks to this excellent Quartzimodo article How to tell when you Seiko watch was made.Unfortunately the Jayhawk Production Date Calculator (by John Gauch) which is linked to in the Quartzimodo article no longer seems to be available, so we built our own.Another useful resource we found during our research was The Seiko Manufacture Date Decoder on the Retro Seiko website.It does not seem to be as well known and we hope that our movement database is more completeand that our instructions are more helpful.As with any part of WatchSleuth we encourage people to contact us with suggestions, corrections or any other information that would make our site more useful.
