All of the watches offered for sale on this website have been completely overhauled by myself and come with a full one year warranty that covers parts and labor.  The overhaul starts with the complete disassembly of the case and movement, then ultrasonic cleaning, inspection and, when necessary, replacement of parts, lubrication and reassembly.  All new gaskets are installed and then the watch is regulated over a period of at least a week so that it is keeping time 0 to +2 seconds a day.  I will then wear the watch for a few days to make sure it maintains these timekeeping standards when exposed to the rigors of everyday wear.  A suitable watch strap is selected and the watch is then listed for sale.
