I am a casual collector of vintage American wristwatches from the 1920's and 1930's. They are miraculous miniature machines and are highly functional. However, they do get dirt and grit in the inner workings, and moving parts wear down over time and need to be replaced. Mr. Diradourian is an expert in the service and repair of antique clocks and watches from America and Europe. He will work and work on something until it is fixed--any problem, bring it back and he will work and work some more until the timepiece works to his exacting standards (it is as much art as science to repair these old timepieces). He is located inside the fabulous Antiquarius vintage jewelry mall, and most of the jewelry dealers carry watches as well and all seem to go to Karnik's to get them in good shape to sell to their customers.
