Damaged Hairspring

Take look at this regular and hairspring. I had serviced this watch and returned it to its owner. It was then sent back to me with the complaint that it did not run, in the state shown here. The owner denied touching anything.

The regular is turned to extreme, and the hairspring is yanked clear out of the watch hard enough that it actually broke. It's harder than one might think to break a pocketwatch hairspring, it's steel after all. This damage took significant force.
My first suggestion was that perhaps there was a curious child in the household, but was told this was not the case.

This happened a number of years ago. The owner paid for the additional repair, but maintained ignorance of what had happened throughout.

New Arrivals

Not a thing wrong with them, just in for routine service...


New Arrival

Many say that these early plastic crystals de-gas as they decay and corrode hands and dial, and even inside the watch. This is true, I have seen it.

This watch appears fine though. It is also said that once the crystal has turned green/yellow, it is no longer de-gasing, after all those decades. I don't know. But glass crystals do show off the dial more and are getting harder to find.

I advice people to replace the plastic ones, while you can.

Job Number 170050

This is a grade 315, 12 size, 15 jewels, made about 1926.

This was a very popular Elgin product.
This watch needed a balance staff.
The old staff is separated from the balance wheel with the lathe and the staking set. The remains of the hub, once broken off, is a little washer. I like to save these, you never know...

See the whole album for this project here.

Testing the motion of the new staff, I find it works well. I did have to reduce the upper pivot some though first. Replacement parts are often not quite right.

I do find though that the balance cock does not sit securely flat. It wants to rock a little. There are two divots cut into the plate from some past repair (to raise the balance cock, likely because the upper pivots on the staff were too big for the upper jewel).
The hairspring collet does not fit the replacement staff. I use this tool to squeeze it closed a bit.
