I have a nice vintage milanese style watch band that I want to put on a watch of mine. Only problem, the band is 19mm at the lugs. I hear that it's possible to file the lugs down to fit. How is this done, exactly? Is it something I can do myself or do I need to take it to a jewelers? I don't have any metal files, but that can be solved with a quick trip to the hardware store. Any and all advice will be appreciated. Here's a pic of the band. I'll be putting it on an early 60s Zodiac Sea Wolf (no date).
