Hi Michael,
sit down one day with paper and pen and watch Bobs videos. You will see what an expert uses to service a watch and if there are different types of tools for certain jobs Bob does a great job showing them and how they work. This is the advice I give everyone that asks that question 
Just bear in mind that Bob made those videos almost 100 years ago (right Bob 
) and the prices he quotes for stuff can be quite a way off now. If you take your time and can get to meets and shows you might be able to pick up some bargains and also keep your eye out on ebay.
Paul.
