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.
