Unveiling the Bremont Terra Nova 38 Jumping Hour Stealth Black: A Tactical Timepiece with a Twist
In the world of horology, jumping hour watches have become a hot topic, with recent releases from Audemars Piguet and the re-emergence of Niton. But the real surprise came from Bremont, a brand known for its robust aviation-inspired timepieces. The introduction of the Terra Nova Jumping Hour models in 2025 was a bold move, and one that has left many enthusiasts intrigued.
The concept of jumping hour complications can be traced back to Austrian engineer Josef Pallweber, who patented his invention in 1883. This unique mechanism, with its modern and digital aesthetic, found its way into wristwatches in the 1920s, capturing the essence of the Art Deco era. But beneath its simplicity lies a complex challenge for watchmakers.
The jumping hour complication replaces the traditional hour hand with a disc beneath the dial. This disc is propelled forward by a spring-loaded mechanism, releasing a burst of energy when the minute hand reaches 60. The key lies in managing this energy release without compromising the watch's accuracy. It demands an energy-efficient gear train that can handle shock loads, and a larger mainspring to accommodate the increased power consumption.
Bremont's Terra Nova collection, introduced in 2024, draws inspiration from early 20th-century military pocket watches. The brand has seamlessly blended the simplicity and ruggedness of these historical timepieces with modern specifications. The Terra Nova 38 Jumping Hour Stealth Black is a testament to this fusion, featuring a cushion-shaped case and a full-black DLC coating, giving it a tactical edge.
Measuring 38mm in diameter and 9.1mm in thickness, the watch is sheathed in a matte brushed DLC-coated steel case and bracelet. The closed caseback, adorned with a world map, hints at its durability, but the 30-meter water resistance might be a disappointment for some. However, the real standout feature is the vertically brushed protective shield over the dial, inspired by the shrapnel guards of trench watches from the early 20th century.
The dial, with its three apertures, follows a montre à guichet design. The trapezium-shaped aperture at noon reveals the jumping hours, while the central circular window showcases the Wayfinder compass logo and a sweeping seconds hand. The arched window below displays the minutes. To enhance legibility, the white Arabic hour numerals and the seconds hand are treated with Super-LumiNova.
Powered by the calibre BC634, a Sellita-based automatic movement with a proprietary jumping hour module, the watch ensures a rapid jump between hours, occurring in less than 1/10th of a second. With a frequency of 28,800 vph, it boasts a Glucydur balance wheel, an Anachron balance spring, and a robust 56-hour power reserve.
The Terra Nova Jumping Hour Stealth Black offers two strap options: a black DLC steel bracelet with a folding clasp and quick-release system, or a black leather Bund strap, reminiscent of the straps used by WWII pilots for wrist protection. The Bund strap, made of black calfskin leather, can be easily switched using quick-release pins, allowing for a more traditional look.
Priced at EUR 5,900 on the steel bracelet and EUR 5,450 on the leather strap, the Bremont Terra Nova 38 Jumping Hour Stealth Black is a unique timepiece that blends historical inspiration with modern innovation. It's a watch that will surely spark conversations and leave a lasting impression.
