Kcore 0 Posted January 27, 2014 I'm contemplating repairing a watch that got damaged recently and need a bit of advice on measuring very small chrono hands that have to be replaced. I've been looking online for a tool and have only come up with the Bergeon 30464, hand guage. While I can purchase it for about $45 USD + S&H , I'm not sure it's worth the investment for me as I don't think I'll be using it much afterward. Has anyone used another method to measure hand hole diameter that they can recommend? After looking at the Bergeon gauge, I realized that most of us hold our removed watch hands on toothpicks. So I was thinking, couldn't I just measure the toothpick's thickness with a digital caliper where the hand stops? Anyone done this - what do you think?
