Looking for a watch for /out/ but I'm also looking for taking it out ice fishing. Where I'm from this means the temperature could get to -20f (-28.8c)

while on my wrist it may not get there, the windchill while looking at the watch may get it really freaking cold. I'm looking at the Pathfinder PAG240-1 from Casio but I can't seem to find the operating temperature.
I know the sensor only goes from 14 degrees to 104 or something, but not really any info on operating temp of the LCD.

I know Casio also makes a Low Temp LCD watch but it doesn't have the options. Or is there another brand that is low-temp with lots of /out/ options?

Gen watch threat too
