Very rare pocket watch signed by Frederik Jurgensen.
It's equipped with extra rare double-wheel duplex escapement and quarter repeating.
Jules Jurgensen is a watchmaking company. It was founded by Jürgen Jürgensen in 1740 in Denmark, when Jürgen Jürgensen went into partnership with Isaac Larpent, under the name “Larpent & Jürgensen”.
Upon Jürgens death in 1811, his youngest son Frederik took over the company and changed the name to Frederik Jürgensen.
Jules Jürgensen produced many fine, different, and fascinating watches in Switzerland, any serious watch collector may consider to own one.
Jurgen Jurgensen was watchmaker of Danish King since 1784. Having a close relations in Switzerland he was one of the leading watchmaker of his time.
While Jurgen Jurgensen left company to his youngest son Frederik, the eldest son Urban has also became famous watchmaker, studied from Breguet in Paris and from Dent in London.
Urban Jurgensen opened separated workshop under his own name, but without doubt brothers are tightly collaborated.
Similar watches are described and illustrated in great detail in "Urban Juergensen & Soenner" by John M.R. Knudsen (and in the Jurgensen Dynasty by same author I believe).
Please take a look on very similar watch by Urban Jurgensen with same escapement below all photos (sold by Sotheby's in 2012 for 11200 swiss franks).
Double wheel duplex escapement is quite rare variation of duplex escapement, found mainly in Danish and English watches.
In quality watches it allows to achieve performance similar to lever escapement, but is more delicate.
The watch is signed on case, dial and movement.
Dial condition is generally good with some minor hairlines at 12 hours area.
Gilt case is in good condition with some gilt losses.
These watches usually comes in golden cases, this one give a chance to buy rare watch by good price.
Movement is in good running condition.
Repetition works as it should, but one gong is slightly loose and quarters sound is a little dull.
Please look video below the photos.
Diameter of the watch is 60 mm, height is 73mm. Weight is 142 grams.
Good collector item.
