3 year warranty
Bremont focuses purely on beautifully made mechanical movements and every watch in our core collection has passed each of the rigorous precision tests necessary for the ISO 3159 chronometer designation. Every movement is finished to the highest levels of craftsmanship and all are guaranteed to within -4 and +6 seconds per day. For this reason Bremont is one of the few watch makers to offer at least a 3-year warranty on every timepiece.

Proudly made in the UK
Great Britain has a wonderful history when it comes to watch making and has probably been the home to more advances in horology than any other nation. Bremont is determined to play a pivotal role in the reinvigoration of this industry on British shores and as a result, Bremont manufactures parts at its Parts Manufacturing Facility and every Bremont is hand-build and tested before leaving the Henley-on-Thames workshop.
Description
Inspired by early 20th-century trench watches, the Terra Nova Jumping Hour Bronze brings together vintage military styling and contemporary watchmaking innovation. Its compact 38mm cushion-shaped case is crafted from vertically brushed cupro-aluminium bronze, a high-performance alloy known for its strength and ability to develop a rich, even patina over time.
At its core is the exclusive BC634 Jumping Hour calibre. This rare complication displays the hours, minutes and seconds through crisp, linear apertures in the montre à guichet style. A compass-inspired sweeping seconds hand overlays the central Wayfinder logo, reinforcing the watch’s connection to navigation and exploration.
Limited to just 100 pieces, this special edition is offered with either a brushed bronze bracelet or a vintage-style tan leather strap. Compact, precise, and rich with character, it’s a collector’s piece built for life in the field.

Limited Edition
Limited to 100 pieces
Jumping Hour Complication
At the heart of the watch is the exclusive BC634 Jumping Hour movement. This high-torque calibre delivers precise hour changes in under a tenth of a second, displayed through crisp, stacked apertures in the montre à guichet style.
Military Design
The 38mm case draws from the geometry of trench watches, refined into a cushion-shaped form with a low profile and shortened lugs for all-day wear. The vertically brushed Cupro-Aluminium Bronze offers both strength and the ability to develop a unique patina over time, giving each piece its own evolving character.
Limited to 100 Pieces
With just 100 individually numbered pieces available globally, the Terra Nova Jumping Hour Bronze is a collector’s field watch that combines mechanical rarity, historic design inspiration, and uncompromising build quality.
