Hadley-Roma
Hadley-Roma's history dates back to 1903, first as the Hadley Jewelry Company, founded by Art Hadley. Hadley Jewelry Co. invented the original expansion bracelet, patented in 1913 and several other designs such as the ratchet folding bracelet in 1934. Roma Industries merged with Hadley in 1986 and ever since, Hadley-Roma has continued crafting fine watch bands and has become the largest manufacturer of watch attachments in North America.
