In 1877, a new prototype was introduced to Benedict and Burnham for an inexpensive pocket watch made of 58 parts, mostly punched sheet brass. They immediately set aside an unused portion of their machine shop and began producing the "Long Wind" at a rate of 200 per day by 1878. The department quickly outgrew its space in the plant, so Benedict & Burnham incorporated Waterbury Clock's sister company Waterbury Watch Company in 1880 with a capital of $400,000 to manufacture and sell inexpensive watches and other timepieces. Waterbury Watch started out very successfully in its early days, employing hundreds of women for their "slender fingers" and "delicate manipulation", and it became the largest-volume producer of watches in the world by 1888.
