Q1: Is this a professional Swiss-made tool?
A: No — this is a China-made aftermarket magnification set. It is not manufactured by premium Swiss brands like Bergeon or Horotec. It offers functional performance at an economical price point for hobbyists and budget-conscious watchmakers.
Q2: What magnification levels are included?
A: The set includes four sapphire loupe lenses at 3X, 5X, 10X, and 20X magnification. This range covers general overview inspection (3X) through extreme detail work (20X) such as examining jewels, pivots, and engravings. Multiple levels let you switch scales without changing tools.
Q3: Why are sapphire lenses better?
A: Sapphire lenses offer superior scratch resistance (Mohs 9 hardness, second only to diamond) and excellent optical clarity. Unlike glass or plastic loupes that scratch easily and degrade image quality, sapphire maintains clear, distortion-free viewing even after prolonged use — ideal for precision inspection.
