Description: Jules Jurgensen, Copenhagen, pocket chronometer, 20 jewels stem wind and key set, cotes de Geneve decorated gilt bar movement with pivoted detent escapement, cut bimetallic balance, gold timing screws and gold endstone settings in an 18 karat, yellow gold, hinged back and bezel, reeded edge, engine turned open face case with maker's details engraved on gold cuvette and Roman numeral, single sunk, white enamel dial, plum colored steel Breguet style hands, serial #5876, 50mm, 106.1g TW, c1870.
Condition Report: CASE: Shallow, small dent, back; Minor dings and pin pricks; Scratches on outer surface of case; Minor scratches on inner surface of case; Engine turning nearly worn smooth; One keyhole in cuvette plugged; Bow worn; Precious metal content marked. DIAL: Hairlines in enamel, very light, center to 11:30, center to seconds bit; A few very fine scratches. HANDS: A few specks of oxidation. MOVEMENT PLATES: Minor marks and scratches on plate; Minor, scattered oxide on a few steel parts; Specks of dirt. MOVEMENT FUNCTION: Running order (winds, sets and ticks). This watch was originally made as a key wind and set timepiece, and was converted to stem wind early on. The mechanism is simple, sturdy, and functions well. It was necessary to rotate the movement ninety degrees in order to carry out the modification without serious alteration to the movement, or adding additional parts to the stem winding mechanism. The plugged hole in the cuvette originally allowed access to the winding arbor. Hand setting must be carried out as it would have originally, using a key to turn the center arbor. Movement and case numbers match.
