A watchmaker’s reputation for skilled workmanship is his most valuable asset. By paying too litle for cheap, imitation parts he can lose his reputation. Be sure you guard your reputation for good work by using parts that you know will be satisfactory.
The manufacturers know they need to supply us with genuine parts. They have known it since 1965 when the Elgin watch company promoted their parts, and from before then, and they know it today. Watchmakers should use genuine parts and the manufacturers should sell them. Our reputation depends on it, and so does their’s.
