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 notable contributions from Audemars Piguet and the re-emergent brand, Niton. But the real surprise came from Bremont, a brand known for its robust aviation-inspired timepieces, with the launch of the Terra Nova Jumping Hour models in 2025. This unexpected move left many scratching their heads, wondering what prompted this departure from their usual style.
The concept of jumping hour watches can be traced back to Austrian engineer and watchmaker Josef Pallweber, who patented his invention in 1883. This modern, digital display resonated with the sleek Art Deco style and made its way onto wristwatches in the 1920s. While the idea is straightforward, there's more to this complication than meets the eye.
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 challenge for watchmakers lies in managing this energy release, ensuring it doesn't disrupt the movement's accuracy. The gear train must be robust and energy-efficient, capable of handling shock loads, and the significant energy consumption requires a larger mainspring.
Bremont's Terra Nova collection, introduced in 2024, draws inspiration from early 20th-century military pocket watches. The brand has captured the essence of these practical, rugged field watches, blending historical charm with modern specifications. The Terra Nova 38mm steel model, part of this collection, measures 9.1mm in height and is coated in a full-black DLC finish, giving it a distinctive tactical look.
The caseback, adorned with a world map, might suggest a higher water resistance, but the watch is rated at just 30 meters, which is somewhat underwhelming for a field watch known for its durability.
Inspired by trench watches of the early 20th century, which used shrapnel guards or metal grilles to protect their dials, the Terra Nova features a black DLC-coated protective shield over the dial. This shield, with its vertical brushing, houses three apertures, creating a unique 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 readability, the white Arabic hour numerals and the seconds hand are treated with Super-LumiNova. The watch is powered by calibre BC634, an automatic Sellita-based movement with a proprietary jumping hour module. This high-torque movement ensures the hour jump occurs in less than 1/10th of a second, a testament to its precision.
The Terra Nova Jumping Hour Stealth Black offers two strap options: a black DLC steel bracelet with a folding clasp and a quick-release system, or a black leather Bund strap, reminiscent of the straps used by WWII pilots to protect their wrists from extreme temperatures. The wider protective bund area can be removed, transforming the strap into a more traditional style.
Priced at EUR 5,900 with the steel bracelet and EUR 5,450 with the leather Bund strap, the Terra Nova Jumping Hour Stealth Black is a unique timepiece that blends historical inspiration with modern innovation. A true conversation starter, it invites discussion on the balance between form and function in watchmaking.
And this is where the controversy lies: Is the Terra Nova's modest water resistance a missed opportunity, or a necessary trade-off for its unique design and functionality? What do you think? Share your thoughts in the comments!
