Installation and Adjustment of Minute and Hour Hands for MIYOTA 9075
【Important】Reminders:
During installation, please avoid bending the post for second hand. Otherwise the function of the movement might be compromised.
Repeated installation of watch hands may result in loose hands. Therefore please be careful with each installation, and reduce the need for re-installation.
An extra set of hands is provided to you in case you need replacement.
Hand setting tools
You will need hand setting tools of three sizes.
Use the left tool with the largest opening for GMT hand
Use the center tool for hour hand
Use the right tool for minute and second hand. [The center second hand’s post goes into the opening of the tool. Therefore, align well before pressing down and after pressing down, avoid sideway motions to avoid bending the second hand’s post]
2a. Installing GMT, hour, and minute hand
We will install the GMT, hour, and minute hands onto the dial and movement assembly.
Installing Second Hand
WARNING! This part is very challenging and poses risk of irriversible damage to the movement!
Tips for second hand installation:
Viewing the second hand from a horizontal angle will make the hand installation significantly easier.
Installing Second Hand
【Important】Reminders:
The second hand post is more fragile than that of hour and minute hands. Please be very careful with installation. A bent second hand post will affect the performance of movement.
It is recommended to first use a loupe to see the smallest post clearly before attempting to install. If you were not careful with minute hand installation, the second hand post might have been bent. If so, it is impossible to install the second hand.
Second hand must remain parallel with the dial. During installation and adjustment, be mindful to keep the second hand level.
