Following the journey of the moon across the firmament has helped mankind measure time since the Mesolithic Age. The lunar calendar, used as far back as in 8,000 B.C., follows the journey of the moon across the night sky measuring time from new moon to new moon as one month. In watchmaking, the moon phase indication is considered the most poetic of watch complications. By definition, a moon phase complication in a timepiece displays the 29.5-day lunar cycle on the dial.
Often associated with classical watchmaking, a moon phase complication in a mechanical timepiece is usually an expensive proposition given the intricacies of the movement. Citizen, however, has introduced it in a more affordable package, albeit powered by an Eco-Drive movement. Meet the Eco-Drive Calendar Watch with Pointer Date, Ref. AP1050-56A.
The watch has a wearable 42 mm stainless steel case topped by a sapphire crystal and depth-rated to 50 meters. The case is slim enough at 10-mm thickness to slip effortlessly under your shirt cuff and is fitted with a closed caseback. The watch is paired with a seven-link steel bracelet with a push-button clasp. The links have alternative brushed and polished surfaces for a more refined look.
A slim polished bezel frames a white dial with multiple surfaces. A textured inner circle houses three sub-dials, one for the month at 3 o’clock, date at 9 and the moon phase indication anchors it all down at 6 o’ clock. The moon phase is represented by a dark blue and grained silver disc. A raised ring on the periphery of the textured inner circle has the dates of the month printed around it. Rhodium-plated hour makers are placed at the periphery of the dial. Time is indicated by lumed, rhodium-plated hands and a central, crescent-tipped pointer indicates the date
As mentioned earlier, the watch is powered by an Eco-Drive movement. Caliber 8651 movement is charged by exposure to light it has an overcharge prevention function. On a full charge, it has a power reserve of six months. A screw-down pusher 2 o’ clock is used to change the month indication while all the other functions can be adjusted via the crown.
At a retail price of AED2,121, Ref. AP1050-56A is a practical value proposition for those looking for an affordable moon phase complication from an established watch manufacturer.
