3. If you buy a 5402 be very careful with the crown and avoid using the quick-set calendar advance feature that comes with cal. 2121. (While the watch doesn't have a date setting crown position, you can quickly advance the date by going with the hands past midnight to around 1am or 2am and then back to 10pm to adjust the date without having to go around 24hrs for each day). This is not an isolated case as on the four 5402s that I've owned I always had problems with the crown stem breaking and the crown coming off will pulling it out to set the time. On one of them this happened twice in a two-year period. When pulling the crown out to set the time, pull very slowly! Another thing to consider will be to wind the watch via the crown by turning it no more than 5-7 turns.
Valuable advise!
I will be VERY careful.
Strange the pdf i downloaded from the AP website says to turn the crown to wind no more than 30 turns.
As for the date setting, i guess each time i set i do it very gently eh.
