Usage Instructions

Pin removal/installation: Select the appropriate blade and pin, mount them on the holder, place the bracelet on the support, and turn the pressing handle to push pins out or press them in.

Bracelet screw operation: Use the matching slotted blades or pin tips and rotate the handle to tighten or loosen screw-type bracelet links.

Height adjustment: Choose either the 6745-SR-20 or 6745-SR-28 base according to bracelet thickness and working clearance, and fine-tune the height.

Mirror disc use: The 7745-P mirror disc illuminates the work area, helping to observe tiny parts.

Installation Instructions

Base installation: Insert the chosen adjustable base (20 or 28) into the positioning slot under the support, then turn the locking knob to secure it.

Blade/pin replacement: Loosen the wing screw on top of the pin holder, remove the existing part, insert the selected blade or pin into the corresponding hole, and tighten the wing screw.

Handle assembly: Fit the pin holder with drum (6745-PG-A) into the vertical slide of the support, and adjust the sliding friction using the knurled nut on the side.

Mirror disc placement: Place the 7745-P mirror disc onto the magnetic or slotted base of the support (refer to actual product), and adjust the angle for best visibility.

Important Notes

⚠️ Always verify that the selected blade/pin diameter and shape exactly match the bracelet pin or screw head. Forcing mismatched parts may damage the bracelet or tool.

⚠️ For precious metal or coated bracelets, place a soft protective film (e.g., clear tape or microfiber cloth) between the tool and bracelet to avoid marks.

⚠️ The adjustable bases are precision components; avoid dropping or over-tightening.

⚠️ Keep the handle perpendicular during pressing to prevent bending the pin or chipping the blade due to lateral force.

⚠️ This set does not include curved support pads for highly arched bracelets; purchase separately if needed.

Maintenance & Service Guide

Regular cleaning: Wipe metal debris off blades and pins with a lint-free cloth after use. Apply one drop of watch oil monthly to the slide and threads for smooth operation.

Worn parts replacement: If blades or pins become burred, bent, or worn, replace them with the spare parts included in the set (7745-MS and 7745-GS).

Handle friction adjustment: If the sliding handle feels too tight or too loose, fine-tune the knurled nut on the side until the desired resistance is achieved.

Base calibration: If the base becomes wobbly after long-term use, check the locking knob’s threads and tighten with a watchmaker’s screwdriver if necessary.

Note: The tool can be serviced by the user without professional help, but do not disassemble the internal spring of the handle to avoid losing small parts.

FAQ

Q1: Can this set work with all brand watch bracelets?
A: Works with most common brands (Rolex, Omega, Longines, etc.) using pin or screw bracelets. Extremely small or large sizes may require additional dedicated blades/pins.

Q2: What is the difference between the two adjustable bases (20/28)?
A: The numbers refer to the maximum working height range (approx. 20mm and 28mm). Use SR-20 for thinner bracelets/smaller work, SR-28 for thicker bracelets or more clearance.

Q3: How to distinguish between blades and pins for different uses?
A: Blades (7745-MS) are flat or slotted, used for driving pins in/out. Pins (7745-GS) are cylindrical with pointed or flat tips, used for turning screws or hollow pins. Try different sizes for the best fit.

Q4: The bracelet slips during operation. What can I do?
A: Make sure the rubber anti-slip pad on support 6744-P is clean and undamaged. For metal bracelets, slightly loosen the screws on both sides to let the bracelet lie flat, or gently hold it with your fingers.
