The manufacture of key-wind movements was discontinued altogether by 1878. Howard also introduced the first stem-winding watch in 1868, and was probably the first to market such a watch in the USA. Reed's patented barrel was used on early watches, but by 1868, Howard patented a new steel motor barrel which replaced the Reed's barrels in Howard watches. Balances were gold or steel at first, and later bi-metallic compensating balances with gold screws were used. This watch also introduced the more accurate quick-train to the American market. The top plate was made in two sections (split plate) and had six pillars instead of the usual four found in a full-plate watch. By the summer of 1858, Edward Howard produced the first watch of his own design, a watch that was entirely different from previous watches.
