altimeter and humidity

[Robertp]

Hi,
I have two questions about my Observer.

1. I have noticed that often when I reset the altitude to local conditions and then confirm the setting with the Mode button, the altitude immediately shifts by a couple of meters (usually upward, though I am not sure). Why would this be?

2. Is the altitude reading affected by humidity? A friend of mine who has the observer told me that the altimeter was useless in Malaysia because the humidity there made the readings inaccurate. Would there be any truth in this?

thanks!

The Observer is 1/3 smaller in both diameter and width than the first generation Suunto Watches (Vector, Altimax, etc). It also features a chronograph, which previously was only offered in the Navitech but is now discontinued.
