In addition to selling under his own name he also supplied to many English retailers.  He almost always used the fusee in a reverse configuration to reduce friction and wear on the arbors.  He experimented with balances on his chronometers patenting flat rim varieties.  His chronometers won many medals for their timekeeping in the later half of the 19th Century.  The firm continued making chronometers after his death in 1890
