no clues yet, but from the pics you can see a slight discoloration
I would have to investigate more and prepare myself for a steep learning curve !

Hi, saw some pictures on other forums of vintage watches restored using laser welding and they are made to look amazingly like new. Rusted cases, bezels etc all restored to look like they were bought yesterday. A great technology if someone desperately needs to restore a watch in absolutely bad condition (like the guy in the other thread who posted his fathers watch going through a washer and dryer which would be a great candidate for laser welding) but also a technology that can be missued to restore watches in bad condition and sell them at a premium as NOS or unpolished stock. I was stunned looking at the results and I hope watch experts will be able to easily distinguish between a restored watch in mint/NOS condition and an unrestored watch in mint/NOS condition. For those in the know, any clues of how one can tell the difference? |

Any clues from the experts here on how to tell if a case has been laser welded or not? I do know some very experienced watch experts can tell but I don't know how, any suggestions, theories welcome! Also a technical article on laser welding http://www.uslasercorp.com/envoy/welding.html |

Impressive. I bet it costs though. Sort of like the quote I got on my car to fix an oil leak, $25 for the gaskets and $2k for the labor. Also this seems to be for stainless cases. Lots of older B's showing the worse wear are plated with either gold or chrome. If the base metal can be done this way then the plating will hide any evidence. |
