Question about Watches
Information on supplier of hairspring for Helbros Invincible wristwatch c.1970, 17 jewel movement marked R74 88b.
Take a closer look at the movement, especially under the balance wheel (use an eyeglass). There should be movement code. By that you can find the real movement manufacturer and the hairspring or balance complete will be easier to trace.
