One of the earliest interpretation of the acclaimed, and still in use today, Louis Cottier’s world time system, the present watch is offered in extremely honest condition. The scale and numerals are engraved/enameled, a very costly and high-quality procedure which gives extremely durable dials as a result. Interestingly, this watch bears a striking resemblance with Patek Philippe's first serially produced world time wristwatch, ref. 1415. Both models share a similar case, dial and even the design of the "compass" hands.
While the present watch does not feature a quick setting system for the city ring (in case of travel to another time zone), the ring can be very easily adjusted by opening the case, a simple and convenient solution to the problem.
