Laser Weld

Hello,

I have been reading up on watch repairs and wondering if it possible to tell if a watch has been laser welded? What do you look for? Are there any draw backs to having your case repaired with this method?

Thanks!

If it is done properly you cannot tell. Welding metal is a well known process.

The alternative grind down the case to meet the lowest point of the damage spot.

It might be possible to tell if you have a sufficiently advanced x-ray machine. I have friends in that business working on both detectors and x-ray sources. I lend a friend a couple of watches a few years ago for testing precision x-ray imaging of machines running. I have a movie somewhere of one of them with a sandwich dial. You can focus on different layers of the watch while the film is running and look at the dial, plates, sprockets. The 1675 was a bit harder to x-ray.
