Moonphase watches are one of the most romantic complications for women, but they’re also sophisticated. Moonphase indications depict the stages of the moon’s rotation cycle in real time using a small disc, typically painted or engraved with them. Through an aperture on the dial, the correct portion of the moon disc coinciding with the night sky is displayed. Those discs, or that display system, can be simple or complex. Simple ones are accurate for about two and a half years, more advanced ones for up to 122. The typical real-life moonphase cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds. In most moonphase watches, this time is condensed to an average of 29.5 days — meaning that in a few years, the accuracy is affected and the watch needs an adjustment.

Bovet Récital 23
From Bovet, this stunning Récital 23 is the first Bovet women’s watch to be housed in the brand’s creative “writing slope” case (inspired by the sloped writing desks of yesteryear). For the first time, though, it is in an oval shape rather than round. The dial at 6 o’clock is aventurine glass with 10 diamond indices, and the two hands form a heart shape once an hour when the hours and minutes overlap. The three-dimensional globe at 12 o’clock is engraved to reflect the moon’s surface and is filled with a luminescent material. The blue discs with stars rotate with the globe, and the moonphase is read via a circular aperture above the Bovet logo. The moon is accurate for 122 years before needing an adjustment. The watch is powered by a self-winding movement with 62 hours of power reserve.
