Purchased watch for upcoming lengthy, "multiple time zone", trip with plenty of time to be spent snorkeling.  Was pleased to see how easy it was to keep track of current time whereever I will be. It is helpful to print off the user's manual off the Casio website for larger print to see the city codes needed to obtain times in other cities. While the watch is equipped with almost three dozen city codes, with a little pre-planning, you can figure out which code will match where you are going.  If internet access during your trip is not available, would recommend writing down city codes that correspond to the cities you will be visiting. For example, ATH (Athens) is the same time as Cape Town, South Africa and Maputo, Mozambique.  With days filled with many activities and specific arrival/departure times, needed a watch that I would not have to take off (due to water), illuminated at night, alarm feature to make sure I get up on time, etc.  While it is not the most stylish for a woman to wear, it's functionality takes priority.  Other comments about the bulkiness of the watch are true but not planning to wear long sleeve shirts or a suit :)  Bottomline, for relatively very little money, you are getting a great watch.  If you lose it or it is stolen during your trip, it is not a major investment lost.
