Good to have what I might refer to as a 'bi-compax'.. my Dad's watch was a tri-compax and what I have read suggests it refers to the three complications of date, moonphase and chronograph.. so two out of three in my hunt, and who knows perhaps my Dad's will resurface amongst my Mum's possessions in the future..Congrats! I recall you've been after one for a little while. :-!
So I went to this site to find out which phase the moon is..
Moon Phases Calendar / Moon Schedule
Now I am wondering if all moonphase watches are made based on the Northern Hemisphere viewpoint.. seen from downunder, the view would be as if the moon disc was rotating counterclockwise as opposed to going clockwise. .
Makes you think..
:- :-!Ok, good luck with that; nothing quite as essential in timekeeping as a moonphase.
Any left, or do you have them all? ;-)
