The current Traveller model is a 91mm Swiss Army Knife from Victorinox that contains the same same layer (bladed) tools as the Climber, extended with the electronic features of the timer and clock functions from the Voyager, and the altimeter, barometer, and thermometer functions from the Altimeter models.

The Traveller Lite adds a white LED light and inline-Phillips screwdriver to the Traveller.

Name Disambiguation:
The original  Traveller (1.3702/54591) was a an earlier model, that had the same main toolset as the Climber, before the multipurpose-hook was added, but without the keyring.
There is another model called the Traveller-Set, which, rather confusingly, is a variation of the Huntsman, which comes in a pouch and with other accessories.

History 

Victorinox had produced several models with timer/clock capabilities such as the TimeKeeper, Voyager and TimeKeeper Alarm and also the Altimeter with meteorological functions. The barometer and timer functions of these models were amalgamated with the introduction of the current Traveller models announced in April 2006.

The original Traveller model was a predecessor to the current Climber, but did not contain the keyring or more recent hook.
