Thread: Casio ProTrek Two Serial Numbers

    Casio ProTrek Two Serial Numbers

    Hi guys I wanted to ask if any have come across a ProTrek with two serial numbers - one at the bottom of the case back, which it usually is, and another on the top. I have this on my PRW5100 and from checking online pictures, it appears to be the norm. Would anyone know what the top one is for. I am interested to know because I wanted to determine manufacturing date. Thanks in advanced.


    Edit - Seems to be the same with PAW2000 models...

    Edit2 - OK it seems that production date cannot be determined from the serial number on any of my ProTrek/Pathfinders. All of them have a serial starting with 2, including my PRG270, which definitely wasn't produced in 2012 or 2002.

    Found out a link that was very helpful: https://www.youtube.com/watch?v=kNQJRj9I-J4

    The presenter explains that the first 3 numbers + the next letter represents the factory where the watch was produced

    The next 3 numbers shows the day if the year

    The last letter signifies the year - starting with A for 2001 or 2011.

    I cannot verify if this is true as this is the first time I have heard/read about this but so far it has somehow been consistent with all of my post 2000 ProTrek/Pathfinder/G-Shock's.
