Watch and Chronometer Jeweling

First published in 1887, Watch and Chronometer Jeweling is a compact bench treatise on the art of making and setting jewel bearings—one of the few 19th-century English-language books devoted specifically to the subject.

N. B. (Napoleon-Bonaparte) Sherwood wrote from serious factory credentials. He had worked at the Boston Watch Co. and then partnered with the New York wholesaler Louis S. Fellows to plan what became the Newark Watch Co., where he served as the founding designing watchmaker before family circumstances took him out of the project. He is also the author of A Practical Treatise on Watch Repairing, a separate volume in this catalog.

Across roughly sixty pages, Sherwood covers the full workflow: selecting and preparing rough gemstones, shaping and polishing the jewels themselves, opening pivot holes, fitting end-stones, and rubbing finished jewels into plates and bridges. The end-shake tool gets its own treatment. The book is short, practical, and pitched at the bench watchmaker who needs to make and set jewels by hand rather than order replacements from a factory—still a recognizable problem for anyone restoring a 19th-century American pocket watch.
