H.Moser & Cie. Endeavour Perpetual Calendar

by Chamath Gamage

As many already know, H.Moser & Cie is all about keeping things simple. Their watches all speak of minimalistic design while still keeping the essence of what makes a modern-day timepiece. This “complexity made simple” philosophy that the brand thrives on is what makes their perpetual calendar timepiece so interesting. Normally Perpetual calendars are a bit more on the busy side when it comes to the dial, but not the case with H.Moser & Cie’s perpetual calendar. 

H.Moser & Cie. released their first perpetual calendar in 2005, and upon its release, the public saw it as one of the easiest perpetual calendar timepieces to read. The timepiece could be adjusted both backward and forward and at any given point throughout the day. In 2015, H.Moser & Cie. released the Endeavour Perpetual Calendar Funky Blue, which not only revived the perpetual calendar model for the brand but also gave it a fresh new take with a new aesthetic design mixing traditional and modern together. 

Now, H.Moser & Cie. is revamping the Endeavour Perpetual Calendar. Keeping the Funky Blue dial, the brand is now releasing the timepiece in a 42mm case size, with a new edition of the brand logo being done in transparent lacquer. 

Alongside the Endeavour Perpetual Calendar, H.Moser & Cie. is also releasing another timepiece, this time as a limited edition. This special commemorative timepiece showcases the brand’s technical characteristics of the latest Endeavour Perpetual Calendar model. The limited-edition variant is there to showcase how the perpetual calendar works, with the technical specifications shown directly on the dial. This means that this limited edition model is no longer minimalistic in design, however is just as mesmerizing to look at. 


This latest Endeavour Perpetual Calendar comes in an 18k white gold 42mm case with a screw-in crown adorned with an “M”. As mentioned previously, the fumé dial is iconic to H.Moser & Cie., is retained in the sunburst Funky Blue colour on this timepiece. Keeping the watches as minimalistic as possible is a great way to show the beauty of the fumé dial, and with a perpetual calendar timepiece, this becomes even more impressive. 

Where normal perpetual calendars can have quite complex dials, the dial of this Endeavour Perpetual Calendar model doesn’t show any complicated sub-dials or date discs, making the time so simple to read. The hour indices on the dial not only display the time but also the calendar months, which is shown through a small hand in the centre. A large date window at 3 o’clock with the “Flash Calendar” function features the instant date change at midnight. The minimalistic sub-dial at 9 o’clock shows the power reserve indicator. The sub-dial at 6 o’clock shows the constant seconds. 

Nearly all perpetual calendar timepieces in the market today need careful handling, with precise instructions that need to be followed for date changes, etc. This makes customers wary of constantly wearing these watches and also tackling the time-consuming process of date and time changes after the watch hasn’t been worn for a while. H.Moser & Cie has innovated and now revolutionised the process in which all this is done, making this complicated timepiece operatable by even a child. The time and date change on the Endeavour Perpetual Calendar is easy to set thanks to the screw-down crown, allowing it to be changed at any time of the day. 

The special limited edition series shows the intuitive functions of the Endeavour Perpetual Calendar illustrated nicely on the dial. The dial of the limited edition models display scrawled notes and drawings which encapsulate the features of the movement. 


The movement used in the Endeavour Perpetual Calendar and limited edition model is the hand-wound HMC 800 Manufacture calibre. The HMC 800 Manufacture calibre operates at a frequency of 18,000 VpH (3hz) and has a staggering power reserve of approximately 7 days (168 hours). Both variants feature a see-through case back in which the movement can be seen. The movement and components have all been hand-finished and decorated with the pallet fork and escapement wheel made from gold for aesthetic and luxury finishing. 

The watch comes strapped in a hand-structured beige kudu leather band with a solid 18-carat white gold folding clasp engraved with the Moser logo. 

H.Moser & Cie. prove time and time again that less can be more. With the latest rendition of the Endeavour Perpetual Calendar, the brand has pulled off the minimalistic approach to perpetual calendars. While most other perpetual calendars on the market have complicated dials, H.Moser & Cie.’s version is so simple it can be operated and read by anyone.
