A well-known model from 1968 – the Memovox Polaris - has inspired the Le Sentier watchmaker for a collection of robust watches with a sporty but still elegant design. This new range debuts with five models, all equipped with in-house movements, that include this world-timer chronograph in titanium. Joining the two chrono pushers is a second crown at 10 o'clock for setting the rotating city disc. All the wearer need do is align the reference city with the red marker at 6 o'clock to immediately see the time anywhere else in the world. And because world time watches can be a struggle to read, Jaeger-LeCoultre has given its watch a generous 44mm diameter. This timepiece exists also with a blue dial.
