That's assuming the Bronzo has the A7750 movement. Depending on the purchase date of the original owner, it may have the A7750 movement, the P.9000 clone movement, or the P.9000 superclone movement. This can be confirmed by first the location of the balance wheel (A7750 - @11, P.9000 clone - @7, P.9000 superclone - @7) then by the function (quick date set/no independent hour hand movement - A7750, P.9000 clone, no quick date set/independent hour hand - P.9000 superclone).
Winding
No special instruction for all movements; give it around 10 winds until the second hand starts moving
Time setting
No special instruction for all movements; pull out crown to 2nd position to change time.
Date setting:
A7750
Do not change the datewhen the time is between 10PM and 2AM, the date change mechanism is engaged and if you do it, you may damage this part.
Proper procedure
1. Change the time by pulling out the crown to the 2nd position and change the time to 6AM (just after the date has changed).
2. Put the crown into the 1st position. Change the date to the desired date.
P.9000 clone
Use the same procedure as the A7750
P.9000 superclone
1, Pull out the crown to the 1st position. Then move the hour hand until the date changes to the desired date. It may seem too much of a hassle but that's the same with the gen movement.
