Our beloved HMT Watches from 80's era also works on Mt. Everest provided you key them regularly, which could be herculean task with those thick padded glovesHi Shashank
This is what you are looking if you want altitude temp pressure GPS compass etall
Suunto - Suunto X10
if you are not satisfied with this one there are other options also available with Garmin but as per my knowledgde this one is the best if you are looking for outdoor features+ GPS.
Garmin is more GPS centric so may not give details of altimeter/barometer in some models but there are 1-2 models which can give all features.
SUUNTO is a finnish company masters of precision instruments/compasses and outdoor wristwatches......they say the only watch which works on Mt.Everest is a SUUNTO
