Loud tick on a fusee clock cured

Recommended Posts

I acquired (another) old fusee wall clock the other week.  Smuggled it into the house and swore blind, when asked, that 'I'd had it forever but it had been in the garage waiting to be sorted out'.

Anyhow, when I'd set it up it turned out to have a disconcertingly loud tick, so much so that it seemed to take over the whole room.  It kept excellent time and was a dream to set in beat but, oh, that tick.

I'm no expert, and I can appreciate some of you may know what I'm about to say, but I'd remembered being told to check the residual tension in the spring, which is meant to allow fusees to work right to the end of the chain.  I did that, and found someone, in setting it up in the past, had given it at least 8 initial turns (and maybe another one 'for luck'), which meant there was a lot of tension in the spring, even when it was supposed to be fully unwound.  I let the tension down to zero and then gave it a turn-an-a-half initial, followed by a wind on the fusee itself to get it going.  The clock still ran perfectly, but the tick was reduced to a whisper.

Maximum winding to full fusee hasn't changed the volume and the clock's now a very welcome and unobtrusive visitor to the dining room.  As I said, some of you may already know this, but I felt it was worth posting for any of you who didn't.

    • Here is the insert ring for rectangular or elliptical movements: Note that the length is the side with the stem cut out on the spreadsheet (in the picture below this is 15.15: Here is the fake pdf file, again you need to convert to .zip after download to access the FreeCAD and 3mf files.

    • as you took the mainspring out what did it look like? It's amazing how much amplitude you can get if the mainspring actually has the proper shape. last week I was doing a 12 size Hamilton and was very much surprised with the beautiful back curvature the mainspring had. Then the watch had a really nice amplitude the group would be so proud it was 350 until I dropped the lift angle down to 38 that drop the amplitude quite a bit below 300. then with the beautiful back curve it still had really nice amplitude the next day. I really wish all my mainspring's look like this as the watch had beautiful amplitude the next day. So many of the aftermarket pocketwatch Springs I see now do not have anything resembling a back curve may be a slight curve and that's about all. They still work but they just don't work as nice as a properly made spring. then Omega as all sorts of nifty technical documentation unfortunately every single corner is watermarked with where it came from who downloaded it etc. very paranoid company. On the other hand I will snip out images like from the document on recycling a mainspring barrel. for instance here's the section on what your mainspring should look like. water damaged a lot of times means rust was there rust on this watch?
    • I dont understand why a patreon membership would have limited places ??
    • Welcome to the forum, enjoy. It’s highly unlikely you will be able to purchase a new bezel look on eBay for a pulsar watch for repair to find a bezel.
