thanks everyone for the very useful information.
Phillipgeorge, if I did not read your message wrong, you are saying you can just advance the date by pushing the hole, then day, month will move forward as well? I have a 5960 and a 5140 but since I purchased them, they are always on the winder, I have no real life experience in setting them. The instruction just say we need to set everything one by one in a certain order.
Regards
