This timepiece was made to commemorate the introduction of the universal time in Belgium in 1892 L’Heure Nationale Belge. Roskopf watches are usually considered to be mass produced low-priced watches. There are, however, exceptions. Some years ago one of these watches was auctioned in a gold case, the only one of its kind one ever came across. This watch stands out because of its lavishly hand engraved case that shows extreme attention to detail. The movement too is distinctive in that the quality of the workmanship is much higher than in the rest of the series. All surfaces are very finely granulated and gilded, the screws and other steel parts are either mirror polished or smoothed.

Fritz Edouard Roskopf was born in La Chaux de Fonds on December 13th, 1835 and died in 1927. In 1855 Fritz Edouard and his father Georg Friedrich Roskopf together with Henry Gindraux established the company Roskopf, Gindraux & Co. Two years later he left the company and started his own business in Geneva. After the death of his father, Roskopf began making his own watches and registered the thistle as his mark in 1897. On January 3rd, 1899, Roskopf received patent CH 18632 for a mechanism that allowed setting the hands with the crown. His watches were produced by the Reconvilier Watch Co SA and signed F.E. Roskopf & Co.
