A traveler from coast to coast, then having a watch permanently set on your two locations will save you the constant hassle of switching times. If you are a business person who frequently needs to know the times of different locations, or if you have family members you need to speak with who live in a different time zone, then having your watch set according to these specific locations will keep you from calling people too early or too late.
While a dual time watch usually performs many different functions, it doesn't necessarily have to look like a sterling silver, while still providing you with the two times you need.
