Vintage Patek Philippe REF. 624/1J 24-hr, Over-sized, 3-Tone Art Decor Pocket Watch
These watches would remind to the travellers the time on which side of the day or the night they were. The present watch is a true Museum piece, unique and technically very important.
The only one besides the Gondolo 24hours series from that period identified to have survived.
An Extract of Archives dated 2019 confirms that the watch was made in 1912 and sold in 1938 with a silvered dial and raised 24 gold hour-markers.
The 19th century saw the rapid development of new means of transportation; travellers faced a perplexing problem: each region had its own local time. The technological advances that had made distances shorter soon led to progress in this area as well.
By 1876, Canadian railway engineer Sandford Fleming (1827-1915) recommended a universal time system with the globe divided into 24 time zones.
This was adopted in 1884 at an international conference in Washington; the Greenwich observatory meridian was taken as the reference and the Universal time defined the local time in each time zone in relation to this base meridian. A capital importance for the advancement of global travel and communications.
