A slightly more expensive option for the traveler is the GD-350 Casio G Shock. Less dressy than the above but it's world time citys menu lists 100 cities in the world's time zones. For example the pacific time zone lists 5 cities, LA, San Francisco, Tijuana, Seattle and Vancouver. Only one selectable at a time so possibly less convenient than the above watches and certainly less dressy as it is a standard large black G shock watch. Cheapest current price on Amazon is circa $80 so still quite reasonable and it includes a unobtrusive vibration alarm.
