Hi to all from Poland.
Just a few lines to tell you all about myself.
Hi to all from Poland….. My name is David. I was born in Ilford Essex 64 years ago and now live in Poland.
My Dad is still alive (just) he is 93 years young and been a watchmaker all his life until he retired 25 years ago. (had shop in Southend Essex)
My interest in watch repairing was not so when I was younger, still not, more into clocks as they say…… BUT this has not stopped me sticking tools into the back of watches……
Mark has been a good teacher, I have been following most of his video’s (Thanks Mark) for all the info.
Now I had all my Dads tools and the rest of his material he had left over, sold quite a bit but still kept some. Also I had the watch he promised me a very long time ago. The watch is a Jaeger-LeCoultre, model number 431673 with the number under the balance, P450/4c.
What I am looking to do with this watch is to restore it to its fine glory, problem is I need a watch case for it, the dial (plus hands) to be restored but most of all I need the centre sweep.
If I can require all these OR FIND SOMEONE TO RESTORE IT FOR ME before my dad departs I can show him that this watch can be restored. As you can see from the photos. So any help will be much appreciated.
Mark, thanks for the workshop info, will be building my NEW one very soon.
It does remove (and compress) material, but it could be just a micron or two to several hundredths or more. Burnishers as used on pivots always have a straight grain texture, this is in effect a micro file. When burnishing on a Jacot tool you are removing a small amount of material as well as work hardening it. It does increase the wear resistance of a pivot. When I make a balance staff I generally leave the pivots 0.01-0.02mm oversize and bring them down to final size in the Jacot tool.
Another lesson learned, I broke the click of a Seagull mov.t (no parts available) while letting down power. Bad design, isn't flexible enough to stay away from the ratchet wheel while do so. Better let it unwind by itself if possible, or be extra super cautious. Anyone can suggest a spring that I can adapt? The hole is 3.5mm.
I'm working on an ETA 1164 triple calendar movement and the day disc does not line up well with its window, see picture. The jumper action seems fine and there are three jumpers for the date mechanism which are all identical.
Has anyone incurred such issues before with this movement? Is the only remedy to adjust the profile of the jumper?
