These experts tackled the challenge of repairing two vintage watches of mine with great sentimental value: a Hamilton Men’s Dress Watch from 1934 that my grandfather gave my father, as a college graduation present and a Girard Perregaux Chronometer that my father gave me 50 years ago. The latter had never been serviced so it needed rebuilding. The former had a broken balance staff, I learned from an expert watchman in London who lacked the part and equipment. The work was done as promised. I delivered the watches on a visit to NYC and they were returned by Fed Ex with no hassle.
