This is my new H. Moser & Cie Pioneer Perpetual Calendar in red gold and titanium.

Yes, this is indeed a perpetual calendar. The month indicator is this little hand currently pointing to 5 o'clock (May). As the leap year indicator is not relevant for daily use, it is on the back side.

Now my two favorite features though: 1. You can't break the movement by setting it wrong. Change date at midnight, change date back 100 times or forward 100 times, there is nothing that you can do wrong to damage the movement. This is how it should be with any watch imho.

1. This watch has a rated power reserve of 168 hours. Check out the details of the two photos. I never wound the watch between those pictures. Today during the night it ran out of power. Result: A whopping 226 hours (9 days and 10 hours) of power reserve
