Patek thus ignores the importance of the central seconds hand in time-keeping.
I did not say that the watch will become inaccurate. I agree that even when the chrono functions are engaged , the time-keeping minutes hand will continue to keep its accurate time, however the seconds hand when reset from chrono-seconds to timekeeping-seconds, will start all over from zero. Thus in my example the actual seconds elapsed in real time and the apparent seconds read-off the timekeeping seconds hand will be incorrect. In my example the real seconds elapsed is 25 seconds but because of the timekeeping seconds hand restarting from zero, the wearer will now read the seconds lapsed as zero when it should actually resume at 25 seconds. Thus if the time is 10:10:25 in reality, the reset of chrono-seconds to once again become the time keeping seconds will cause the time to now show 10:10:00. This is not welcome at all. Perhaps this is the very reason that no one tries to mix up the chrono-seconds counter with timekeeping-seconds counter ( normal seconds hand).

the chrono second hand can run continuously and DOUBLE as a second hand because of the lack of friciton in the 28-520 and evenly distributed energy to the chrono modual and time keeping, BUT does not replace or act as the real second hand. Internally, the...

Hi, Indeed the 5980 (and 5960) doesn't have a permanent seconds hand. Time is indicated only by hour and minute hands. Due to the construction of the calibre you can let the chrono engaged permanently if you want, meaning also that you can use the central...

If the chrono-seconds hand is left running as a permanent timekeeping-seconds hand, then it would also lead to the chrono-minute hand and the chrono-hour hand ( in the sub dial at 6' O clock) running continuously. This leads to the following questions 1. ...
