A new model from the British company Arnold & Son, producing its watches in Switzerland, is named TB88. It means "True Beat" - the name of the watch complexity, the task of which is to provide an abrupt movement of the second hand, instead of a smooth, having a frequency of 8-6 movements per second.
That is, the most part of the time the hand is fixed and only after the end of the second it is making its jump - this mechanism is not only an aesthetic improvement, but also a way to save some energy winding springs. This complication has been very popular in the XVIII-XIX centuries. Jumping seconds were set in marine chronometers, to provide more accurately determine longitude by the watch.
