First Twin Sensor Alti - Thermo
This watch always reminded me of a horseshoe, another example of how consequently Casio puts functionality over aesthetics. But the good news is, the altitude sensor is working great!
This was also my personal golf weather forecast system in Switzerland. By observation over a longer period of time, I noticed, that a sharp decrease in air pressure will be followed by rain in about 6 hours. That is, for Northern Switzerland at least. The 24 hour histogram lets you verify that very easily and I was really surprised how many times this watch saved me from a soaking wet round.
The strap seems to be not that great, my father was wearing his watch extensively while hiking and the strap broke after a relative short time. I guess, sweat and the high UV exposure in the Alps might have been the reason.
