I just recently caught the bug and have acquired 5 watches in the past month. I am going to stop for a while. However, I would like to be able to change and adjust my own bands myself. I am somewhat competent with tools having worked on motorcycles, cars and bicycles over the years. What do I need for this? I notice, for example, my Breitling Pro II has really tiny screws in the band. Is there a set of specific band changing tools? At this point I have zero intention of attempting any other work on my watches, just adjusting and changing straps, bracelets, bands. Thanks for any suggestions.
