No, it is not the training of the icon from the Steiermark / Styria but the service by an expert-watchmaker of a special watch-movement from John Roger Arnold (1769 - 1843), the 19th-century London-based Chronometer-watchmaker, Breguet-scholar and colleague of the important English Chronometer-makers Charles Frodsham & Edward John Dent.

Preserved in excellent and working condition the technical delicacy comes with a Duplex-Escapement. Interestingly the watch can be dated exactly to 1842 by the London-hallmarks for 18K-gold and this is right the year before the death of the important watchmaker, innovator and scholar of Abraham Louis Breguet. One of his most important innovations was the compensation-balance -- a balance of bi-metal that reduces the influence of the most disturbing factor in watchmaking / precision: temperature-variance.

So, a temperature-compensation. And this is just one point where architects of highly precise modern quartz-watches shake the hands of artisans and innovators like John Arnold and other important Chronometer-makers: in the pursuit of precision even in a changing (ie. real-world) environment.

Yes, a watch that shows the right time; during the start of the H.M.S Beagle in the cold of Plymouth, UK on 27th of Dec 1831 and also in the heat of Bahia, Brasil on February 28th, 1832. Obviously the historical importance of Chronometers -- the ship with Charles Darwin on board (H.M.S Beagle) carried 22 of them with some made by Arnold & Dent -- cannot be overestimated.
