    New PRO TREK PRG-270-1A with Photos

    My first ABC watch arrived last week from Japan, the PRO TREK PRG-270-1A. I considered the PRW3000-1A but I preferred the looks of the PRG-270 even though it feels a tad large. Plus I didn't feel the need for the atomic sync on this one. I'll be using it while snowboarding, hiking, outdoor photography etc.

    The one question I do have is about the sensor at the 9 o clock position. Is there any reason why it bulges out like that or is it just cosmetic? There doesn't seem to be an issue squeezing the sensor into the slimmer PRW3000 case. Added protection perhaps? Also has anyone unscrewed that sensor cap? I'm tempted to see what's under there.

    I have not dismantled my PRG270 before but being a v3 sensor, it should be just like my Rangeman, which I have dismantled before (bezel and strap).

    On the Rangeman, it is very much cosmetic.

    The Rangeman has a "bulge" on the left where the sensor is located at.

    When I took off the bezel I was like "What the...... ?" when I found out there was really nothing there but a plastic piece that made up the "bulge" under the bezel. The sensor was well hidden inside the movement with only a metal piece covering it.

    There was no reason at all in having the bulge except to give it a more "balanced look" (what with the huge ABC button on the right side of the Rangeman).

    So, I suspect it is the same thing in the PRG270.

    Cool. Did you snap any photos? If I unscrew just the sensor "cap" there isn't anything super sensitive that I could mess up is there? I've owned a few G-shocks but I've never taken them apart.

    Here's a previous photo I had of my dismantled Rangeman.
    Sorry for the crappy shot.

    If you look at the movement/module, the ABC button sticks out on the right.
    But on the left side of the movement (where the sensor is supposed to be located) is nothing but a flat metal piece, some sort of covering. The sensor is behind that.

    Just next to the movement (on the left of it) is the grey plastic piece that is the "bulge" which goes into the empty space on left side of the bezel.

    However, as I've said, I've not dismantled my PRG270 before so I cannot say for certain what's actually behind that sensor area.

    So if you do try to dismantle it, please do be careful !

    Thanks for sharing! I figure the PRG270 will be similar. It is surprising that nothing extends out of the inner case, yet almost all of the case designs have that extra bump or space around where the sensor is. There has to be another reason.

    My guess the space is for trapping air for the pressure gauge (sensor) to sample. The PRG270's sensor is really not that protruding, it's just an illusion from the bulge above the bezel. More bulge = more manly. Don't worry about it, it's a great watch as it is. Just enjoy your new watches!

    Here's my most recent photo.
