The search for birth year watches provides another reason вЂ“ as if any was necessary вЂ“ to search for more cool vintage watches. Imagine the gravitas such a watch would have as a jewel in oneвЂ™s collection. How much easier would it be to justify the cost of a birth-year watch. вЂњImagine if I could just find that Rolex Sub, you know? With that dial that I really dig but that was also made in the year or even the month of my birth.

Tales of $25 Rolex watches bought at the local thrift shop or found at the bottom of a battered box of worthless non-runners at an estate sale reverberate through our mind, urging just one more search, one more clickвЂ™ deep into the early hours of the morning. The thrill of opening the next box or clicking the next link to see if it might be hiding something different. We love a chase donвЂ™t we? Watch enthusiasts I mean. In case that a watch was produced in two different factories, the subsums for factory where then added up.Collector GuideBirth-Year Seiko Watches: 1960-1969

All cases were built into actual watchesДЇor the analysis of absolute production numbers, the dataset was thus evaluated for the maximum serial number per calibre/case/subcase/factory code/YM combination and all the maxima over the production timeframe were summed up.

Each Factory code has an own serial number (if thus watches were produced in two different factories within the same month, both factories applied their own serial number).

Serial numbers are reset once a month, first watch produced carries serial number YM0000.

g., separate serial numbers for 6309-7040 vs.

Each case/subcase combination has an own serial number (e.

The data I will present are thus to be interpreted as ballpark numbers but in my opinion are (1) the best data available so far and (2) should give at least a good impression of which numbers we are dealing with beyond orders of magnitude.Дata for 6-digit watches are thus are based on the following assumptions:

Furthermore, it must be clearly noted that the data in my archive are not yet at all sufficient to allow an accurate determination of absolute numbers. At this stage, I can only present data on watches with the 6-digit serial numbering system, I have not yet found a way to interpret the 7-digit that makes sense to me.

Seiko Model Number Guide This is the first time I try to publish some figures on the absolute production numbers of the series I study. 15 %).ДЄs of August12 2012, the archive contained a total of 1570 caseback pictures of divers watches, figures 1 and 2 show the distribution of the data set per movement (figure 1) and for movement/case/subcase combination (figure 2).Figure 1 Data source for the divers watches: eBay (approx. Data were imported and analyzed with MS Excel. The first part deals with Seiko Serial Number Dating the distribution of my current data set, then for the first time I will publish some results on absolute production numbers and eventually a timeline of the manufactured models.Д¬aseback data were stored in the format of pictures with calibre, case, subcase, factory code, YYMM and serial number contained in the file name. Model series included in the study cover the automatic 300 m models as well as the 'classic' 150 m divers (6217, 6105, 63). finder.htm This page is dedicated to my studies on production numbers and -timeframes of Seiko Vintage Dive watches. It does help to know a little about movement production dates when dating watches on the street but if you have a computer handy you can always drop by these fine websites: If you see a Zero it is a letter O for October N= Nov D= DecДЁDXXXX would be December 2008 8OXXXX would be October 2008 ДЄ note on months since only one numberis used for the months Oct / Nov / Dec being two numbers is noted by letter 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. Most Seiko serial are 6 digits long and so a serial of 86XXXX would be a watch made in April of 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 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 All Seiko's should have a Serial number on the case back
