I have a couple Oris watches (Orii?). One is their "Worldtimer" watch. It is a great travel watch. I have a slightly older version of this model. The new ones are a bit different but the movement is the same. I prefer it to the GMT style for travel. I have had it for about 10 or 12 years and been very happy with it. On this model the +/- buttons adjust the hour hand on the main dial by one hour with each push. The small dial keeps your home timezone.
