Stems for American Pocket Watches

During the early days of our pioneers of watch and case makers in the United States, of which there were some 10 to 15 companies, did not agree on inter-changeability as to the thickness of movement or systems for winding or setting the watch. The only complete watches ready for delivery over the counter were Swiss Watches. As American movements and cases came separately, consumer would select a case and movement to his fancy and budget. As it was, only certain styles of movements would fit in certain style of case and the jeweler would be obliged to carry a selection of movements, cases, stems and sleeves to assemble the watch. The American stem and sleeve system period extended well past the introduction of the modern Swiss system in the 1920's. Today, with the modern watch it easy to order the correct stem just by giving the caliber number and not even to know what had to be done in the years past fitting stems to Pocket Watches. If takes a skill watchmaker trained in this task to fit a stem, sleeve and crown to an American Pocket Watch. Files and a lathe may needed to adjust the stem for a proper fit, which is complication by the continued depletion of the available selections of old stems and sleeves for American Watches. Today, as in the past the watch repairer is mostly on his own when it comes to selecting stems, sleeves and crowns for these watches and fitting them to the case and movement.
