The Jaeger-LeCoultre’s 8-day Mappemonde desk clock (Ref. 163) has become incredibly collectable in recent years. With a delicate glass globe overlaid with paper gores (to a scale of 1:65,000,000,) the Mappemonde is not only a gentleman’s globe, but also a rather novel take on an approximated world-time clock. The gores themselves are by J. Forest, with an address on the globe noted (17-19, Rue de Buci, Paris).
