A. Select the appropriate polishing compound based on case material
B. Remove the movement and all internal components from the case
C. Apply masking tape to protect the crystal
D. Measure the case dimensions for documentation
The movement must be removed and safely stored before any refinishing work begins.
Polishing generates metal particles, dust, and moisture that can contaminate or damage the movement.
This is a foundational safety and quality requirement in all professional refinishing protocols.
A. The case back threads
B. The crystal, crown, and pushers
C. The lugs only
D. The spring bars
When complete disassembly is not possible, masking tape must be applied to the crystal,
crown, and pushers to prevent polishing compounds and debris from entering the case or damaging
delicate components. Polishing compound on a crystal is difficult to remove and can cause permanent
damage.
,A. Cut the spring bars with side cutters
B. Use a spring bar tool to compress and release the spring bars
C. Pry the end links off with a case knife
D. Twist the bracelet until the spring bars release
The proper and safe method for bracelet removal is using a spring bar tool, which
compresses the spring bar allowing it to be released without damaging the lugs or the bracelet end links.
A. The case serial number only
B. The watch brand only
C. Any existing damage, dents, or deep scratches
D. The customer's contact information
Pre-service assessment requires careful documentation of existing damage, scratch
depth, and any impact marks. This documentation protects both the watchmaker and the customer, and
informs the refinishing approach.
A. To absorb polishing compounds
B. To protect the case from scratches and provide stability
C. To cool the case during machine polishing
D. To measure case dimensions
A casing cushion (or case holder) protects the case from scratches while providing a
stable grip during disassembly, reassembly, and handling of delicate components.
, A. In a plastic bag with other components
B. In a dedicated, dust-free container away from the refinishing area
C. On the bench next to the polishing lathe
D. In the ultrasonic cleaner
The movement must be stored in a dedicated, dust-free container away from the
refinishing area to prevent contamination from metal particles and polishing compounds generated
during the refinishing process.
A. A flathead screwdriver
B. A case knife with a sharp, thin blade
C. Pliers
D. A hammer and punch
A case knife with a thin, sharp blade is the appropriate tool for bezel removal. It allows
controlled leverage at the bezel/case junction without damaging the case or bezel surfaces.
Screwdrivers, pliers, and hammers are inappropriate and risk damage.
A. The case back threads may strip or gall
B. The movement may become magnetized
C. The crystal may crack
D. The crown may detach
Excessive force during case back removal can strip or gall the case back threads, causing
permanent damage that affects water resistance and requires expensive repair.
