What makes a horological trend is difficult to define, but the recent arrival of several timepieces that has decreased to a method that has recently been popular almost a century ago indicates that “jump time” are very strong.

The Spring -hour system replaces the convention of two hands that circulate around a regular dial in order to be visible (most often) a few rotating slices – marked with hours and minutes – by separate openings.

Instead of simply having a network spring and balance bike setup that regularly supplies electricity, a jumping hour clock contains an additional system that stores energy that is suddenly released when the minute CD reaches its 60-minute mark so that the hourly disc progresses to the next number.

Such movements represent the watchmakers additional challenges, both because more energy is required to drive the discs forward as for conventional hands (the windows more heavier) and because of the difficulty to synchronize them perfectly so that the new hour is displayed at the same time as in the last minute of the previous – hence the term “diving hour”.

During the 18th century, French horologists dealt with early versions of the system to produce “Wandering Hours” pocket watches, with the great Abraham -Louis Breguet created the first true jumping point in 1785.

It was not until 1883 that the system was patented by the Austrian engineer Josef Pallweber, and it was only in the 1920s that it was reduced in models such as the Rolex Marconi to wristwatch size and, known, the Cartier tanker à Guichet, which was comparable to the windows to the windows of a window of one of the windows of one window – to the window of a window – a slice of one of the windows of one of one of one GuichetOr ticket office.

The complications for jumping lessons have occasionally been revived by brands such as a long & sons (with the Zeitwerk from 2007) and Gucci, which launched the skateboard-inspired, jumping hourly grip model in 2019. Recently there have been examples of Makers, including makers, Chanel, Chanel, Gerald Charles, Gerald Charles.

However, they rarely have as many attention -strong jumping hours as they have in 2025.

Louis Vuitton started the ball in January with its drum convergence, while the tank revived the tank on the watches and miracles last month.

The two Bremont models were unexpected, especially because the Terra Nova range is connected to robust, adventurous watches, while jumping time models are generally viewed in the clothing category.

In the past, however, the complication returns to a time before a resilient sapphire crystal was used to protect the watch figures.

Bremont offers such a design with a bronze housing and the steel version (shown here), which contains the diving hourly mechanism behind a conventional “complete” dial with a medium second.

Both use the same BC634 movement made for Bremont by Sellita for Bremont and licensed for the exclusive use of the brand by 2027.

The “high torque” gear enables the hourly disc to make its important jump in just a 10th second, while the power spring offers sufficient performance for 56 hours of autonomy.

The 40.5 mm -Terra Nova diving hour in steel costs £ 3,750; The 38 -mm -Terra Nova Jumping Hour bronze (limited to 100 examples) costs £ 4,550 for a leather strap or £ 4,900 for a suitable bracelet.
