Knowledgeable, fairly priced, responsive. I came into possession of a 1970 Rolex Datejust that needed serious cleaning and servicing. I brought it to Manhattan Time Service for a quote, which I received 2 days after leaving the watch (they need to open it, take it apart, and see what needs cleaning or replacement). I felt the estimate was fair given the amount of work the watch needed to be back in running condition, so I accepted. They gave me an estimate time for completion of the work and they delivered as promised. The watch looks awesome, I have been wearing it almost every day for about 2 months and it has been keeping time with a precision +/- 3 sec per day, which is amazing for such an old watch. Highly recommended.
