I love the mechanics of the IWC Da Vinci Perpetual Calendar watch, but it suffers from a serious issue for show-offs: The mechanism only works in one direction. So now I give you the ultimate perpetual calendar: H. Moser & Cie.’s Endeavour Perpetual Calendar. It’s the cleanest, simplest, friendliest perpetual calendar watch on the market, and unbelievably gorgeous besides!
When it comes to stealth complications, this H. Moser & Cie. Perpetual One is about as good as it gets. Lurking under an understated and classy exterior is a mean horological machine with a perpetual calendar and double barrel power to last all week!
