About Monard

The private label was produced by the famous Jules Monard Geneve manufactory for the US distributor house, Williams & Son. The original name of the maker can be found under dial. Monard was active during the late 19th-early 20th Century, and has been credited with making ‘high grade’ watches. His timepieces were imported by Wittnauer into the early part of the 20th century, at which point the company has since disappeared.
