In the local St. Louis area and looking for a good local watchmaker to service a few vintage pieces. Have a Speedmaster Straight Writing - 69 plus a few other neo-vintage pieces like a Great White GMT and Seamaster 2351.80, this being my daily driver for years. Started developing a patina and want to keep original as possible.

Any advice and assistance is appreciated.
