Hello everyone, I have a question. What causes hairline cracks on the
dials of old pocket watches? Is thermal expansion/contraction due to
extreme temperature changes a factor, or is rough handling usually the
culprit? I have a Waltham railroad grade pocket watch with a perfect
dial, and I'd like to keep it that way. Thanks.

The serial number is 14090324. It's an 845, and I believe it was
manufactured in or around 1904.

Piecing information from a couple of online databases Waltham
designated movements by the first year they were manufactured so that
would be an 1892 model, grade 845 that was manufactured between 1904
and 1905. It's a size 18 openface movement with 21 jewels. This
movement may have been adjusted to 5 positions and use a lever release
to allow setting time.
