I think it may be handy for all members to chime in on who they use for service as well as some other details. Please only chime in if you have had first hand experience with the service provider. Please include details such as what you had serviced and if you would recommend or not.
Chronosky Miami- Great indy service center for entry level to mid level watches. I would say from Movado to Breguet. These are your guys, fair prices, and while wait times are not short (1-4 months depending on the piece) this is kind of standard now a days, if not quite a bit shorter than normal.
Swiss Watch Repair Co on Madision Ave in NY- Alkis is a true master watchmaker. Top notch work for all the best brands. Lange, AP, Patek etc... Prices are high and wait times are long (sometimes over a year) but the work is truly top notch and he can accomplish almost anything. Highly recommended for your special watch projects.
