Rolex GMT Master - a watch for the travelling man

The clocks go forward tonight to start British Summer Time and it's an opportunity to look at a watch designed to be worn in multiple time zones. Designed originally for pilots in collaboration with Pan Am Airways in 1954, the Rolex GMT Master has since gone through several design changes, but remains essentially the same, despite Rolex's recent efforts to over-bling their products.

Several simultaneous times can be kept by using the red 24-hour hand and twisting the bezel. This avoids compromising the accuracy of the watch by moving the main hands to adjust to a new time zone.

Although a Rolex is not cheap, it will hold its value well, unlike lesser watch brands whose second-hand values plummet in a car-like fashion immediately after purchase.
