Another Slice of History

Here’s another interesting page out of the annals of horological history in North America. The following is a price list for “Watch Repairs To The Trade” that I came across not too long ago, in a box of old watch movements and watch literature from the 1950s, at an estate sale.

The Last 100 Years

How Jewel Bearings for Watches are Made

Ever since John Harrison first used them in his H4 pocket watch, to defeat the longitude problem, jewel bearings have played a pivotal role in the precision of nearly every serious watch or chronometer produced since.
