Triple Calendar Moonphase Watch. The zenith chronomaster original triple calendar limited edition for hodinkee is a tribute to a rare prototype el primero from 1970 that accommodated a triple calendar moonphase module atop the a386 movement. I’ve always had a thing for triple calendar moonphase watches.

Many triple calendars also include a moonphase complication, forming a classic gentleman’s watch of the 20th century. Triple the fun with the zenith chronomaster original triple calendar.this exceptional timepiece features a complete calendar (day, date, month) and moonphase.
