Der neue Drehring ist jetzt satt orange:
A full service for the movement and the case refinishing was 365 Euro (incl. shipping/handling - the watch in the pictures also needed a new glass, dial and hands). The same service for the Mark XII is about 100 Euros more, due to the JLC movement (vs. the ETA in the Aquatimer). Refinishing a steel bracelet is 60 Euros.
Normally, they try to find the middle ground between polishing out the dings and not shaving of to much material. Thus, very deep dings etc. do not go away completely. For very heavy damage, they use lasers - i.e., new material is "melted" onto the respective part and then refinished.
