The present watch draws immediate attention for its sophisticated dial design, featuring the map of America and its surrounding area, painted elegantly with blue translucent lacquer on a silvered surface along with diamonds and sapphire-set decoration. Reference 5719 is a magnificent beauty in terms of artistry and complication, featuring a very creative mechanism which switches the time between two countries with a simple press on the pusher at 8 o'clock. Designating a change between two time zones specifically, it is very convenient for frequent travelers and serves a perfect companion.
