Some G-Shock watch models come out and are made for many years to follow. Others are retired after only a couple of years. So what if you have a G-Shock watch that isn't a higher end model with a serial number and want to know how old it is -- is there any way to know? I'm not entirely sure.
But I'm thinking that there may be a method to know when the model of your particular watch was first manufactured, by checking the YEAR field. When in the settings mode and you navigate to the year, step it down until you reach the "bottom", the last year before the year indicator turns over and shows the maximum value. For instance, I have a GW-2310 and I wanted to know when it was first released. Unfortunately the sites that usually have this kind of information are having trouble, so I wasn't able to locate this. What I did was just go to the year field in settings mode and step it down, finding the year "2000". This matches the release year of the G-2300, which I know because I had researched this watch some time ago.
I'm guessing that every time CASIO makes a new batch of watches of an existing model line, their technicians do not reprogram the firmware to set the lowest year value to the current year. I think it's "burned in." So, a watch that was made in 2011 but is a model that was first made in 2000 will not show "2011" as the lowest year. It will be "2000." It sure would've been great if CASIO bothered to set the year to the production year, so you'd be able to very easily know when your watch was made.
By the way, if this YEAR value technique is accurate, then some of the on-line information provided is faulty. Case in point, the GL-110. I made a write-up of the GL-110, and from what I'd read from My GShock and Watchshock, the GL-110 first debuted in the year 2000. But I just went and checked the year value of my GL-110, and the lowest year is 1995! So that poses a few questions:
- Was the GL-110 module first created in 1995, but the watch was later released in the year 2000?
- Was the GL-110 watch actually released initially in 1995, and then other variants came out later?
- Or, did CASIO actually produce the GL-110 in 2000, but their programming team leverage existing firmware code and just didn't bother to update the year from 1995?
- Is this discrepancy with the claimed release year and minimum year setting on the GL-110 an exception to the rule, or is there no set rule at all -- the lowest year can be the current year or earlier depending upon various factors in the module programming effort?
So, does anyone know if there's some reliable method by which you can find out when a particular watch was manufactured? Maybe a stamping somewhere inside the watch?
