Notes

Such chronometers with a single going barrel, were developed by Louis Clément François Breguet, the grandson of Abraham Louis, following his return from Switzerland. Their movements were designed to be manufactured at a much lower cost than the regular double barrel than produced by the firm for the Marine. They were usually sold the the Merchant Marine or individual clients.
