The annual calendar is the poor man’s perpetual calendar. Is it? In some cases maybe because the absence of a leap year mechanism cuts the cost. The all new Lange 1815 Annual Calendar is a very clever watch that still doesn’t take account the leap year but at the push of the button at 2 o’clock it makes up for that. Push the button and the essential calendar settings will move one day ahead. Problem solved.
Another remarkable feature is the hand-wound movement. Sounds silly a hand-wound calibre in a calendar watch but with 72 hours power reserve you can afford to not wear it every and still be in check with date, day, month and the phase of the moon. And if you leave it for more than 72 hours you just wind it and push the button to get back on track. Not a poor man’s perpetual at all, it’s a clever calendar. Interesting price too. For 37,000 euro you buy a whole lot of watch from a unique manufacturer.
