G-Shock Gdf100-1A

How well does the GDF100-1a Perform

In which way? I have 3 of them. Temperature is corrupted by your body temp. Altitude is course (5m increments if I remember correctly). Barometer should be good.

Good looking G with a lot of wrist presence. One of the few g's produced these days that are still asymetrical.

I see but by how much (on avg.) is the temperature skewed

I genuinely don't know. It would depend on how far the temp is from body temp. I live in Hawaii, so most of my Casios read 29.3C.
