Who Is H. Moser, Anyway? H. Moser, as we know it today, operates out of Schaffhausen, Switzerland – a town best known for being the home of another watch company. 

The H. Moser Endeavour Perpetual Calendar, formerly known as the Perpetual 1. This incredibly thoughtful perpetual is absolutely the manufacture's most popular timepiece, offering something that frankly does not exist anywhere else.

The perpetual calendar complication is one of the most complex complications there is. Perpetual calendar watches display the date while keeping track of the month, the year, and whether that specific year is a leap year, automatically adjusting based on the number of days in each month, even February, even during a leap year. Not only are they mechanically complex, but they’re also typically visually busy, as they need to display a lot of information. But that doesn’t have to be the case. Consider this H. Moser & Cie. Endeavour Perpetual Calendar. Moser proves with this timepiece that while perpetual calendars are complex mechanically, they can still be simple aesthetically. 

This H. Moser & Cie. Endeavour Perpetual Calendar is actually the direct descendent of Moser’s first watch post relaunch in 2005. The Perpetual 1 introduced the world to Moser and their unique minimalist take on the perpetual calendar timepiece. It was such a groundbreaking watch that it won the Grand Prix d’Horlogerie de Genève in the complication category. This Endeavour perpetual calendar carries the torch for that foundational timepiece and continues to show why Moser is a brand worth paying more attention to.



Our Endeavour Perpetual Calendar is best known for its simple design. It shows only the time, date, month and power reserve. It compensates mechanically for the differing number of days in the months, hence the name perpetual. The sapphire crystal case-back reveals the H. Moser HMC 341 movement as well as the leap year cycle. The remarkable design of the Perpetual Calendar is possible in part due to the ingenious display for the month: this short central arrow hand uses the 12 hour indices to indicate the month. The H. Moser big date display is also very rare in that it is a flash calendar, generating the power to change the date in a fraction of a second. This combination of exceptional solutions led the Endeavour Perpetual Calendar to be recognized at the Geneva Watchmaking Grand Prix in 2006.
