This watch works great for world travlers - got this for my husband when he started flying world-wide - he says it keeps him from having to manually add/subtract and keeps accurate time.  He likes the weight and says it is comfortable to wear and now wears it at home as well as when traveling.

One word of caution - when you first get the watch, it can take up to a full week to get enough of a charge to work if you're dealing with gray winter days - sunlight charges it up much quicker.  After it's charged up the first time, it appears to work great - even goes into sleep mode when not wearing it to conserve the battery.  Well worth the price!!!
