The Bergeon set of parallel-flanks blade is a professional-grade, single-size hardened steel driver designed to meet the exacting demands of precision bracelet screw servicing. With a blade diameter of 1.20 mm, the tip is engineered with parallel sides (rather than traditional tapered geometry) to intimately engage screw slots on metal watch bracelets, minimizing slippage, tool marks and damage to high-end links. The blade material is heat-treated to approximately 59 ±1 HRC, ensuring long-term edge retention and reliable repeat performance. The stainless steel body offers durability and the knurled handle provides a secure gripeven under fine, controlled pressure. Ideal for bench techs working on luxury time-pieces where bracelet link screws require exact match tooling, this Bergeon blade stands out for its engineered precision and Swiss-manufactured quality. Use it when you need dependable engagement, accurate torque and minimal risk of marring the screws or bracelet finish.
