Bunny wailer sings the wailers rar. Step 1: Serial Number All modern Seiko watches have the date of manufacture contained in the 6 digit Serial number. Exceptions are pre-1970 models when the numbers were 7 digits long, and limited edition models may have a number reflecting it's piece number e.g. F E A T U R E S. Stainless steel case with screwed back with serial no 720048. Seiko Diver's 6309-7290 Japan. Model: SEIKO DIVER 6309-7290. Manufacturer: SEIKO DIVERS, JAPAN. Case: Original (stainless steel). F E A T U R E S. Seiko Diver's 6309-7290 Automatic 17 Jewels Serial Nr.

'When was my Seiko made?' We hear that a lot here at WatchSleuth so we built this page to help you figure it out.The page includes a calculator along with instructions and example images to help you find the movement caliber, case code and serial number on the back of your watch.The calculator uses these codes to do its magic.

Your results will be shown here.If you don't know how to find these numbers on your watch please read our instructions below.

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: Samehadaku naruto movie.

• movement caliber
• case code

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.

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:

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

Using this additional information we can update our three examples:

1. the 6119 was first made in 1970 so #1 is from 1970 or 1980
2. the 6309 was made from 1976 to 1987 so #2 is from 1982
3. 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:

1 = January
2 = February
3 = March
4 = April
5 = May
6 = June
7 = July
8 = August
9 = September
0 = October
N = November
D = December

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:

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

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.

Seikos have the date of manufacture written into the serial number which is engraved on the back of the watch also the movement-model numbers are also engraved onto the case back. The first number represents the year and the second number (or letter) represents the month (1-9 for Jan.-Sept. and O,N and D for October, November and December).For example if the serial number was 864825 and you knew the watch was made sometime in the 1970's it would indicate it to be made in June 1978. You have to know the age of the watch to the nearest decade so sometimes it can be a little bit difficult. Usually the case style or the introduction dates of the movement can help to narrow this down though.

General rule for manufacture month/year is to look at 1st digit of serial # to say what year within decade. Then look at 2nd digit/letter to tell month. For month, 1-9 are Jan thru Sep, with 'O' for Oct, 'N' for Nov, and 'D' for Dec.

For decade itself, you have to know the actual production dates of the movement itself. If you don't you could e mail Seiko customer service in (Japan) ,quoting model and serial numbers and they should be able to help,here is their e mail address below
