Sold under Gross Margin Scheme

The Grand Lange 1 Moon Phase was first introduced in 2014 with a large moon phase indicator placed at the center of the main dial. Not only making it look more distinctive but it is also accurate for over 100 years once its correctly set.

It measures at a contemporary 41mm case diameter with a slim 9.5mm profile and crafted in 18K Yellow Gold.

It has an ivory argente dial crafted from solid silver with a classic Lange 1 asymmetrical layout displaying the moon phase indicator prominently with a big date and power reserve indicator.

The Grand Lange 1 Moon Phase is powered by the Cal. L095.4 which highlights its large moon phase indicator that only need to be corrected by one day after 122.6 years once the watch is correctly set and assuming that it keeps running. It is achieved by utilising the hour-train to keep the moon phase in constant slow motion with a seven gear train.
