Glashütter Uhrenbetriebe GUB, Glashütte/Sa., Case No. 12857, 190 x 170 x 195 mm, circa 1970

A remarkable skeletonized ship's chronometer with 56h power reserve with original operating instructions
Case: plexiglass. Dial: silvered. Movm.: brass movement, bimetallic chronometer balance with 4 weights and 2 screws.

A marine chronometer that is unusually accessible… Whereas this type of chronometer is generally very well protected in wooden boxes and brass cases, this model in a plexiglass case and box does not only happily show its movement – additionally, both plate and dial are skeletonized and allow the viewer to admire the spring chronometer escapement and the open barrel. The original mahogany wooden case is enclosed.
