My Concord Quartz watch, which is dear to me because it was a special gift given to me in 1985 by my late husband. It is also a beautiful watch. When it suddenly stopped working, I took it to Tourneau, where he had purchase it and without much of a look, they quoted me an astronomical price range. I left them and began to do research to find a reputable watch repair place. Manhattan Time Service turned out to be just such a place. First they tried replacing the battery. When that didn’t work, they kept it further for examination and ultimately replace the circuit board for one-third the price quoted by Tourneau. It is working perfectly now. I had a very positive experience and Jacob was friendly and helpful.
