 William Wwichert was located at 112 But Docks in Cardiff, South Wales, between 1871 and 1885.
Note: Little is known about the life of William Weichert, nd few and far between are the chronometers from his workshop.
 He was born around 1830 in Austria and went to Wales around 1859, where he worked at 112 Bute Docks, Rothsay Terrace, Cardiff.
Later, his address was 119 Bute Docks. Weichert and his wife, Elizabeth, had seven children.
 In 1866, he obtained patent no. 2446 for the "Construction and arrangement of chronometers,
 barometers and thermometers". Weichert also produced pocket chronometers, deck watches and nautical instruments.
 Weichert took part in the exhibitions in Paris and Havre in 1867 and 1868, as well as in the chronometer tests of 1873 in Greenwich.
 The dial of this chronometer is engraved with "Golden Cross and Crown from His Majesty the Emperor of Austria";
This indicates that he has also been a supplier to the Austrian Navy, one of the largest fleets
 in the world until the First World War. Its home port was Trieste.
