Full Hunter in a Keystone J. Boss Gold-Filled Case, c.1903
This is a genuine Elgin pocket watch made around 1903 at the company's factory in Elgin, Illinois. The movement is a 16-size Grade 241 running on 17 jewels, with nickel damascened plates, a safety pinion and a fast/slow regulator.
The case is a Keystone Watch Case Co. 'J.Boss' full hunter, gold-filled and guaranteed for 20 years when new. The engine-turned back is still crisp, with a plain central cartouche that was never engraved. The hunter lid springs open cleanly and snaps shut tight.
The white enamel dial is signed Elgin and is in excellent condition, with no chips or hairlines. It carries bold Roman numerals and a sub-seconds register at six, with blued spade hands. The case measures 50.2mm across.
Mechanically it is honest and working: it winds smoothly, sets cleanly by pulling the crown, and runs well. The only cosmetic note is light surface scratching to the crystal.
A well-preserved, running American full hunter, ready to carry or display.
