Sensor watch

A multi-function watch; altitude, temperature, barometer as well as the usual time, chronograph, stopwatch and so on.
It is pre-GPS, but I have had a new battery put in and everything seems to work.
I was given it a few years ago and have hardly used it. I found the altitude function useful for identifying how far up a mountain I had got, and the thermometer for boasting how hot/cold it was during my run or walk.
