Are you open to other things that would make your timepiece go faster. Does it have a bimetallic balance wheel for instance? Often times they get squeezed they're no longer round the arms get bent in that would speed you up. Also when you're looking at your balance we'll make sure you have even pairs of timing screws. It's amazing how fast you'll go if you're missing one of the timing screws so there have to be opposite pairs in other words if there's a screw on one side there should be a screw on the other side. If the hairspring is magnetized has oil on it or anything that causes it to be stuck together. Or for that matter it's touching anything. Also how was the balance wheel removed from the bridge oftentimes they're unpinned as do not do not have a stud and if that happens somebody will shorten their spring. -

Matt Henning in Massachusetts can do the pivot, he specializes in this sort of work. Hi website is basic but his work is outstanding. https://www.henningwatches.com/index-2.html -

Added, with a new unique address for this forum. One simple option for some security would be make them understandable but not correct; like swap the parts before and after the @, and using at rather than the symbol? eg. xyz.com,at,johnsmith It should hopefully prevent web scrapers / spam bots recognising them? -
Here's my first proper post, copied from the one I made on the NAWCC forum last week, so far unanswered. I am working on an antique French carriage timepiece. It's a good make (Hollingue Freres who produced for Drocourt), with lever platform by Joseph Soldano (who also supplied Dent), all freshly overhauled. It runs with a good amplitude at the usual 18000bph. But it gains time massively - about three minutes each hour (that's over an hour per day!). The wheels are all perfect with no damaged or missing teeth and the silvered Soldano platform is almost certainly the original. Now, the escape wheel has 15 teeth and its pinion has 8 leaves - all pretty common. It looks original but in the absence of any other explanation, I'm wondering if it's a replacement and if the original had 15 teeth and seven leaves. If I were to change the platform for one with an escape wheel with 7 leaves, it would obviously run slower while maintaining the 18000bph, but how much slower? Is it a simple math question of seven-eighths as fast as the current one with 8 leaves? 63mins x 7/8 = 55mins would mean it's far too slow. What am I missing here? @nickelsilver
