What does service (COA) include?
A COA begins with complete disassembly of the watch and movement. Movement parts are put through a series of ultrasonic cleaning machines. Pivots are inspected with a 10X loupe and burnished if necessary. Jewels and bushings are pegged by hand with sharpened pegwood. Endshake and sideshake are checked and adjusted as necessary. High quality (Moebius, PML, Molykote, etc.) horological oils and greases are applied as the watch is reassembled. A COA includes simple polishing of the case, installation of a case back gasket, and balance poising, if needed. A new mainspring and additional gaskets may be installed for a small additional charge. Move involved case and/or bracelet refinishing is also available at an extra charge. Following assembly, the watch is tested and adjusted in multiple positions to ensure adequate balance amplitude, beat, and rate.
