The first of Seiko's 6105-8xxx series of watches came in two main designs and were produced under four reference numbers, which were produced from 1968 to 1977. For simplicity, we can break these variants into two groups: the Seiko 6100-8000/ 6100-8009 and then the later Seiko 6105-8110/6105-8119. Other clues to the model decade can be the watch styling or branding, for example Seiko Advan models are associated with the 1970's. The six digit serial numbers are found on Seiko models beginning from 1966. Previous to this Seiko used a seven digit serial number with a similar format. Sep 01, 2019 The Seiko Chronograph Automatic (brown and black dial) has a reference number of '6138-0060T'.

Seiko Watch Serial Numbers Reference List
Calibre, reference and serial numbers Since we are still waiting for the delivery of our Seikos, now is the time to talk about a very important subject: the watch numbers. Again, while we're focusing here on Seiko watches, there are similarities with other brands so please pay attention. There are 4 lots of numbers which are important for proper identification. 1. The first number is the movement caliber:- This number can be found on the watch mechanism itself. Here, it is engraved on the rotor bridge: 6119 C. The letter after numbers indicates version (A, B, C etc) Calibre number is essential when ordering MOVEMENT parts.
- It is located ON THE WATCH DIAL underneath the 6 o'clock position. Very fine print, you need an eye glass to read it. This one is 6119-6020S. What does it mean? During the watch production, each movement can be fitted with practically an unlimited number of dials. Black, white, silver, gold, different height, day/date or date only etc. And each dial would have corresponding calendar wheels and set of hands. Therefore 6119-6020S means that dial set is 6020 S style (black dial, silver hands with luminous material, silver hour markers etc) and it is married to movement calibre 6119. This number is essential for ordering dial parts.
- Again, it starts with the calibre number followed by the case style number: 6119-6023 The case style describes the physical case properties:
steel, gold, gold plated, dimension, water resistance, type of winding crown, bracelet, crystal, bezel and many other external components. However some components are both movement and case related - like the stem.

The first digit on the case back represents the LAST digit of manufacturing year decade. If you know the decade of production (70s, 80s, 90s) then you can figure out when your watch was manufactured. The second number/letter is the month. 1=Jan 2=Feb etc 9=Sept 0= Oct *note this is 0 not letter O N=Nov and D=Dec So my watch was produced in December ???4. As you can see, the number alone is not sufficient to determine the actuall age of the watch (unless you have a new-ish one) but based on the movement calibre and style, I would guess that most likely it was made in December 1974. The rest of the digits present is actually the serial number 3410. It was a #3410 of reference [6119-6023] produced in month of December. Finally the letter F (yellow) is country code - while the case back is stamped JAPAN the watch could still have been produced in Seiko's overseas factory. Obviously, it is absolutely crucial to know the calibre, dial number and model reference number when referring to your watch or when ordering spare parts. It is always a good idea to quote ALL numbers to your spare parts supplier: 'I need [this part] for Seiko caliber 6119 C (note C!) dial number 6119-6020S and case number 6119-6023.'
