There is no charge for an estimate of what is needed to return the watch to working order. At the very least it will need a COA (clean, oil, adjust) which involves cleaning the movement , removing all old oil and replacing with new oil, and changing the gaskets, plus pressure testing and calibrating the movement. This service costs $495. If additional parts are needed, we will inform you as to the cost of these parts. We will not begin any work until you have approved the charges.
