H. Moser & Cie’s latest moonphase timepiece is accurate to 1,027 years

Collectors of H. Moser & Cie’s fine watches know a thing or two about conservative luxury. Unusually void of any branding whatsoever — even on its dial — it’s clear the Swiss manufacturer champions high quality and unadulterated beauty instead. These two ideals clearly shine in its latest moonphase watch, the Endeavour Perpetual Moon.

This watch is deceptively simple at first glance. As part of Moser’s Concept collection, it continues the tradition of replacing markers, indexes, and numerals with a statement dial — in this case, aventurine. You’ll recall the same idea was used on the Endeavour Perpetual Moon Concept Vantablack last year, which saw a dial rendered in the world’s darkest artificial substance. The pitch-black dial took the mystery of the moonphase complication to the next level, and it is this same allure that the aventurine model hopes to achieve too. 

Long lauded for its ethereal shimmer and deep rich hues, this man-made compound of molten glass and copper fillings portrays the beauty of the star-lit sky at night with incredible depth. Its mesmerising splendour is met with classic Moser leaf-shaped hands for the hour, minutes, and seconds. A subtle AM/PM hand rotates on the central axis every 24 hours, indicating AM from 12 to six o’clock, and PM from seven to 11 o’clock.

Yet the star of the watch remains to be its complication and this is where H. Moser & Cie really delivers. As one of the most precise offerings in the market, its movement only sees a day’s deviation every 1,027 years. The moon’s orbital period is precisely 29 days, 12 hours, 44 minutes and 2.9 seconds, and the Endeavour Perpetual Moon Concept manages a deviance of only 0.23 seconds a day, adding up to a full day only after more than a millennium. 

The in-house HMC 801 hand-wound calibre runs this incredible show within, with a seven-day power reserve and an interchangeable Moser escapement module that makes adjusting the watch fuss-free.

The natural satellite is rendered with a textured metallic surface and depicted against a blue background in keeping with the colour scheme. The waxing and waning of the moon have always been one of the most poetic occurrences in the sky, and this limited edition timepiece is a shining example of how the majesty of the cosmos can be so accurately depicted on our wrists, both in theory and beauty.
