Manhattan Time Service is excellent. I have worked with Manhattan time service on the refurbishment of four vintage pocket watches – family heirlooms. Each time, I have found their estimates to be reasonable given the complex work and restoration involved. Their customer service is efficient and organized, and they complete their work on time. Jacob, and everyone else I have, met, is a pleasure to work with, and very knowledgeable – I look forward to my visits to the shop!
