Dating seiko watches calculator

The date of manufacture will then be calculated using the first 2 digits of the serial number and a database of movement manufacture dates.

You will also be given a link to check its value and if available useful links such as to manuals etc (I am currently adding these to the database).

Unfortunately the volume of traffic is forcing me to move to paid servers.

I will never charge to see results and dont want popups or too much getting in the way.

Here we have a Vintage Citizen Case back, this is an Analogue Digital Temperature watch, that made its debut in the early 1980’s so I know the decade.

The important number we will concentrate on is the 8 digit serial number.

Thanks Nicolae [IMG][/IMG] [IMG][/IMG] [IMG][/IMG] [IMG][/IMG] [IMG][/IMG] As far as I know , the production of 7S36 started in 1996 . Thanks Nicolaethat sometimes give an incorrect answer.

On the other hand , I do not know about D-December , N-November etc - this is not mentioned in the Production Date Calculator .

All Seiko's should have a Serial number on the case back The first number in the Serial is the last number in the year of production, and so if it is a new watch and you see an 8 it should be the year 2008 The second number in the Serial is the month the watch was made if you see a 4 it will be the month of April most Seiko serial are 6 digits long and so a serial of 86XXXX would be a watch made in April of 2008 The key to the whole trick is knowing what movement is in side and older movement like the 6309 was made in the late 70's and 80's and so a watch with 86XXXX would be April 1988 and so on ... Someone (on the net) offers Seiko SKX781K or "orange monster" with following description: * 7S26-0350 (so it would be: movement 7S26 & case no. Then using the calculator, found production date is August, 1996?

I hope this helps, it is not always as straightforward with dating vintage Citizens, as the case-back information changed over the decades.

I know this is a 1970’s model, therefore the first digit equals 1972, the second digit is the month so 1 equals January. Months 1-9 are Jan –Sept, O, N and D equal October, November and December respectively.

You can also use the Seiko Calculator, but you still need to know the decade.

Nope, you're mixing the serial number with the case type number. Someone (on the net) offers Seiko SKX781K or "orange monster" with following description: * 7S26-0350 (so it would be: movement 7S26 & case no. Then using the calculator, found production date is August, 1996?
