An elegant watch with an exceptionally accurate moon phase display…

For whatever reason this is the first I have written about Swiss watch brand H. Moser & Cie. on the blog.  Perhaps because its PR efforts are about as understated as its watches.  But for those of us who like the sophisticated, understated look, H. Moser is definitely a brand to keep in mind.  While relatively obscure , the brand is known amongst watch collectors for its exceptionally graceful watch designs and well finished movements, as well as its commitment to post-purchase service.  Prices for its watches start at around $10,000 and go up from there.

This year at Baselworld, H. Moser introduced two new models.  The one I am sharing with you here is the H. Moser Perpetual Moon.  This watch features a moon phase display which deviates only by a single day after more than 1,000 years.

The complicated gear train of the Perpetual Moon watch translates the interval of time that it takes the moon to orbit the earth so precisely that the resulting deviation is only 0.23 seconds per day. Or a whole day after 1,027.30 years.  In order to achieve the extraordinarily high display accuracy, the moon disc must be securely attached to the hour indicator and run with it continuously.  Here is a slightly closer look at each variation:
