A. Lange & Sohne Langematik Perpetual Watch Available On James List
The perpetual calendar complication has been a fascinating and useful feature on high-end watches for quite sometime. Calendar functions directly related to keeping the time, and offer a variety of information related to the 24 hour cycle. Most watches have just the date, and the more complex you get, the more calendar functions you can record. Annual calendars measure the day, date, and month - often the phase of the moon as well. The benefit for those is being able to avoid adjusting your watch each month that does not have a 31 day cycle. Though there is still the matter of dealing with a 29 day February.Perpetual calendars step it up a notch by taking into consideration leap years, which occur each four years and affect the length of February. Perpetual calendars are named as such because they don't need to be adjusted very often. The next time any perpetual calendar watch needs to be adjusted (by one day) will be the year 2100. This sounds sexy even though none of us will be alive

AP wrist shots
Can I request AP owners to show some wrist shots of their AP's? Particularly AP RO 41mm and your wrist size? I have a 6.5 wrist with 2 inches flat on top and was wondering how it would wear on me. Currently I wear a 40.9mm IWC Portuguese chronograph and it seems like the perfect size for me but maybe I can still go up to the Port automatic which is 42mm. Never tried on an AP though... Besides, you guys can have the chance to show your AP's here. :) Thanks in advance. Hoping to be an AP owner one day.

AP 26331 vs Rolex 116509
With a steel sub as the only other piece in your collection which would you opt for? Or is the answer simply to wait for a possible in-house movement in 2018 for the AP or a ceramic bezel on the Daytona? This is not a personal dilemma I am just curious what everyone would go for :). Don't forget to state why you made your choice in the discussion !
