My understanding is that this is a two letter code for the expiration date where the first letter is the month and the second is the year. Unfortunately I cannot find any information on-line on how to convert these letter codes to actual dates and contacting Energizer was not fruitful.

The best they could come up with is use the battery and if there is a problem, let us know. I am posting here on the off chance that someone in the watch repair business, that replaces watch batteries as a sideline, might have inside information on how to decipher these cryptic date codes. In the future I will avoid all Energizer batteries but that does not help with these.

Serial Number: The serial numbers on modern.

In a previous article that detailed the different variants of the reference that were produced over its production lifespan, we mentioned that it is generally believed no more than 36, units were produced of the model. Since the publication of that article, we have continued to undertake research to try to establish a better estimate of production numbers, and also try to get a more accurate handle on the relative numbers produced across the three major dial configurations of Printed, Carved, and Raised logo dials.

One result of this research is that we are extremely confident that we have now also successfully decoded the logic behind the movement serial numbering, something that has — to the best of our knowledge — never been documented before. Stamped on the inside of the case back of the watches can be found the case serial number. Comprised of seven characters, we explained in the previous article how the first two characters of the serial number can be used to determine the month and year of production.

Excepting production in the months of November and December where the year and month codes are reversed , the first character of the case serial number indicates the year of production, and the second the month January through to October are identified by the numerals 1 through 0, November and December are identified by the letters N and D.

We discussed in the previous article how, from an examination of many examples of the reference, we had for the first time been able to establish some logic behind the counter part of the case serial number. We also explained that it appeared that the case number counter was increasing at a faster rate than the movement counter number, thus questioning whether or not it could be used to provide a reliable estimate of production numbers.

The movement serial number can be found engraved on one of the bridges of the movement. Previously it has been suggested elsewhere that the first two digits of the movement serial number can be used to provide an indication of the year the movement was manufactured. However, as we will prove for the very first time in this article, this is not the case.

The s saw many in the watch industry looking to capitalise on increased demand for automatic watches. This article focuses on its earliest incarnations, the X. Production of the Seiko line up ended sometime in , but are still readily available today. The X series is quickly becoming very collectable pieces thanks to a combination of great design and storied history. The first watch company to lay claim to the title was Zenith, who introduced their first prototypes on January 10, The second contender was a collective of watchmakers, which could be termed the Chronomatic group, namely Heuer, Breitling, and Hamilton-Buren.

The companies created a mutually beneficial partnership and worked together in developing their automatic chronograph. The group laid claim to the title by introducing the Chronomatic prototypes on March 3, , in a much-highlighted press event. The Chronomatic group was also the first to show several models of pre-production samples during the Basel Fair in April of , a more impressive showing when compared to Zenith, who had fewer samples during the same event.

These early watches were to be released to the Japanese market only. Some serial numbers of the earliest Seiko s indicate a production date of March or even as early as February , but it is unclear if these are samples or were the first ones intended for the Japanese market. To sum it up, Zenith may have been the first to announce the development of the first automatic chronograph, but Heuer, Breitling, and Hamilton-Buren were the first to release their automatic chronograph to major retail markets.

However, when it comes to who first achieved serial production of the automatic chronograph, Seiko may have quietly beaten both, by releasing to the Japanese market in May Aside from being the first automatic chronograph to achieve serial production, the Seiko was also the first automatic chronograph in space.
