I called my watch “go to” person, Jeff at Kirk Jewelers. He sent me to the site of the American Watchmakers-Clockmakers Institute (www.awci.com). There’s an area where you can put in the brand of your watch, where you live, and then theyll find someone who is an expert on that brand. I did the search but unfortunately, no one came up. I also tried New York with no luck. So sorry.
