A broad term for any clock made to be used when travelling. In the 17th century it usually took the form of an extremely large watch, but bracket clocks and even lantern clocks were made during the 17th and 18th centuries to accompany travellers. They were provided with stout wooden carrying cases, but if pendulum-controlled could not, of course, keep time during an actual journey. Thomas Tompion made at least two clocks which could be converted from pendulum to balance control for travelling; early domestic clocks were very expensive and it was often convenient to be able to carry one's own clock. The Capucine and pendule de voyage were the French ancestors of what is now known as the carriage clock which, with balance control, were made in enormous numbers in France during the 19th and early 20th centuries. They were fitted with carrying handles and protective outer cases in a style which was often copied in England and North America. The modern travelling clock, which is known as a calotte, unfolds from its case to stand on the hotel bedside table. Among early clocks it is important to distinguish between those which are travelling clocks (pendules de voyage) and those which have handles merely for moving about the house. (pendules portatives).
