Patek Philippe's world time wristwatches are among the most distinguished creations of the revered firm. Patented by the celebrated Louis Cottier, the ingenious concentric rings mechanism allows for immediate knowledge of the time in every time zone of the world at a glance. Patek Philippe released a modern incarnation of the world time feature with the introduction of reference 5110 in 2000. The present wall clock was part of a series distributed to the most distinguished Patek Philippe retailers as marketing support for the launch. Offered in remarkable condition, this timepiece is a nearly unique opportunity for the Patek Philippe collector to own what is, literally, the "greatest" word time watch.
