Hi everyone. I am looking to get into cleaning and servicing Waltham pocket watches, which I am collecting. I was wondering what gauges of screwdriver I would need in a starter pack. Obviously I am looking the best quality I can get without spending too much. The following A*F set, for example has 0.60, 0.80, 1.00, 1.20, 1.40, 1.60, 2.00, 2.50 & 3.00 mm heads

An additional 0.50 screwdriver of the same type can be purchased individually for £3.95. Is there anything missing or superfluous from that set would you say?
Many thanks,
Ray
