A professional pin punch for compressing spring bars and exchanging watch straps without damaging the lugs.
Product overview
This watchmaker tool is a professional pin punch built around a smooth flat tip and a knurled metal handle. The tip slips between the lug and the strap, presses the spring bar inward and releases the strap. With proper technique the lugs stay scratch-free, which is critical on a Rolex Submariner, an Omega Speedmaster or any polished case. Owning the proper instruments is the first step toward enjoyable, repeatable watch servicing on the bench at home or in a professional workshop. This watchmaker tool belongs to a broader range of horological accessories trusted by amateur restorers, vintage watch collectors and professional repair benches alike. Every stage of a watch service from case-back removal, gasket inspection, movement cleaning, bracelet sizing to crystal pressing benefits from dedicated, correctly sized instruments. Investing in the right tool prevents costly scratches on polished bezels, broken lugs, sheared screw heads or damaged spring bars. Whether you service a Seiko 5, an Omega Speedmaster, a Rolex Submariner clone or a Bergeon-compatible reference, working with proper hand tools dramatically reduces the risk of damaging your timepiece. Many enthusiasts start with battery changes on quartz watches and gradually move to bracelet adjustments, then case-back openings, before attempting movement work. Each phase needs its own specialised instruments, and assembling a full kit over time is more economical than buying a closed boxed set. Always work on a clean, well-lit bench, ideally on a soft mat that catches small parts, and keep a magnetic tray nearby for screws and pins. Lubricants like Moebius oils, drying papers and a dedicated dust blower complete the typical workshop. Combine this item with a watch holder, a 10x loupe and a fine screwdriver set ranging from 0.6 mm to 2.0 mm for a fully functional repair station. The hardness of working surfaces is calibrated around 55 to 60 HRC on most professional benches, ensuring repeatable results without marking the workpiece. Used carefully and stored away from humidity, this watchmaker tool will support hundreds of services without significant wear, and will pay for itself after only a few interventions on quartz or mechanical calibres.
