The movement similar to the other chronometer by Kullberg in this catalogue. A little earlier and larger, configured to be fitted in a hunter case. The English type winding has not been utilised in this display case but the movement can still be wound and set with a key. Victor Kullberg was born in Sweden in 1824 and moved to London in 1851 where he established a business making fine watches and chronometers. 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
