• You can sort the designs of Seiko watches and narrow them further using the movement number and the various serial number portions. The last four digits represent the model number you are looking for. Write out the entire serial number and the breakdown of its components for future reference and add it to your collection.
• Serial Number: The serial numbers on modern Seiko models are comprised of 6 digits. The first digit indicates the year, the following character the month and the remaining 4 digits a unique production number. The month is listed as 1-9 for January to September, then 0.

Seiko Spring Drive Limited Edition Titanium Chronograph Caliber 5R86 model SPS001 with power reserve indicator, 24 hour hand, small seconds sub-dial and second time zone. Satin finished titanium case and watch bracelet with polished bezel. White and titanium color dial with date calendar and 72 hours power reserve indicator.

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.

Seiko Watch Models Identification

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
