Description: Jules Jurgensen, Copenhagen, man's quarter repeating pocket chronometer, 32 jewels, stem wind and pin set, cotes de Geneve decorated nickel bar movement with pivoted detent escapement, cut bimetallic balance, gold jewel settings, gold timing screws, gold escape wheel, wolf's tooth winding and whiplash micrometric regulator in an 18 karat, yellow gold, engine turned hunting case with Jurgensen lips, now converted to open face, with maker's details engraved on gold cuvette and Roman numeral, single sunk white enamel dial, plum colored steel Breguet style hands, serial #8961, 51mm, 120.4g TW
Condition Report: CASE: Two small, shallow dents, band, back ; Minor dings; Fine scratches on outer surface of case; Fine scratches on inner surface of case; Engine turning nearly worn smooth; Bow worn; Crown worn; Precious metal content marked. DIAL: Minor fine scratches, minor fading to figures on seconds bit, otherwise very good. HANDS: Speck of oxide on minute, otherwise very good. MOVEMENT PLATES: Minor marks and scratches on plate; Crown wheel with scattered specks of oxide; Repeat barrel bridge with fine scratches and polish; Gong base with speck of oxide; Some screw slots with minor marring. MOVEMENT FUNCTION: Running order (winds, sets and ticks) ; Balance rim slightly bent. COMPLICATION FUNCTION: Functions properly. The pin for the setting mechanism originally had a locking stud, attached to the inside of the front cover, which prevented movement of the pin unless the front cover was open. The stud was removed when the conversion to open face was carried out, as it was no longer needed. This safety feature predates Jurgensens bow setting, and is not often seen. The tab for mounting the locking stud remains attached to the inside of the front bezel, and so the locking function could be restored by a competent workman.
