Back in my days one of the first things I did after serving my full apprenticeship was to write too many of the watch companies and ask for a price list of their full watch service. I took in to consideration low and top grade watches. It was very easy to work out prices, one thing I ditched was part repairs, never worth the time, it would be a full service or the customer could find another watchmaker. A watch glass would be replaced at the owner’s risk, if anything went wrong it would be a full service. I never ever looked for work but I found the clock side more interesting and concentrated on that, I still did watch making but I cut it down.
