An English gold double open faced triple calendar watch with moon phases and world time indication, circa 1900. The watch features a Swiss movement with a lever escapement. It has two dials: the front dial is white enamel with Roman numerals, an outer minute ring, three subsidiary dials for the day, date, and month, and a subsidiary seconds dial. There is an aperture for moon phases, and it is marked at the top with Greenwich Time, signed above the day and date dials by Henry Lewis & Co., London. The back dial is also white enamel, displaying seven subsidiary dials marked for New York, St Petersburg, Calcutta, Melbourne, Vienna, Berlin, and Paris. The case has gold bezels and a pendant, with pushers in the band for manually adjusting the calendar and moon indications. There is a pusher beside the pendant to simultaneously advance the time on the front dial and all seven subsidiary time dials on the back, with a regulation arm beneath the back bezel.
