Swiss public transport is excellent- there are train stations at Geneva and Zurich airports under the terminals.
I trust large organisations like Seiko - so comfortable that the Compass Alpinist is rated to 200m. I only tested mine to 2 metres in the sea and unlikely to go deeper! Incidentally there are 2 other Alpinist case shapes, also rated to 200m, that do not have the compass bezel
You have a 1959 reinterpretation Alpinist and I beieve mountaineers in 1959 wore a lot of leather. I used my leather strapped Alpinists whiltst skiing a few times but only once for hiking.
According to the Hamilton website the Intra Matic Chrono dates from 1968 - so 4 years after the HEUER Carrera.
