During the 19th century, transportation by rail and ship increased, which brought the world closer together. It is hard to believe that a single country like Germany did not have standardized time. Moritz Grossmann, a renowned watchmaker from Glashütte, advocated for the establishment of universal time with globally regulated time zones and a 24-hour division, as proposed by Sandford Fleming. When the system was finally implemented, there was a great interest in ‘World Time’ watches, and numerous models were created. A particularly notable example is the current large and heavy pocket watch with two undamaged coloured dials that display day and night, as well as the local time for 43 cities worldwide.

Around 1880 the Swiss watch manufacturer J.L. & A. Beguelin was based in Tramelan and listed in Bern. L. Beguelin from Bern received the US patent No. 34506 on July 13, 1868, for a ‘universal’ clock (World Time clock) which displays the time for various cities around the world, the clock has two dials. The front dial with Roman hours, I-XII in each half, an outer minute track, outermost 24-hour numerals, and a revolving centre with different time zones and the names of 25 world cities. The reverse with the names of 43 world cities and a central revolving dial calibrated from 0-60. On September 17, 1885, L. Beguelin received the British Patent No. 11,050. The watch has the addition of the ‘Greenwich Patent’. There are indications that the company Beguelin & Co SA later emerged from this venture.
