Bremont Limited Edition Terra Nova Jumping Hour Aventurine

Bremont expands its Terra Nova Jumping Hour line with the launch of the Terra Nova 40.5 Jumping Hour Aventurine, a limited edition exclusively unveiled at Dubai Watch Week 2025.

Limited to just 50 pieces worldwide, this new model brings a striking new material to the Terra Nova collection, pairing a deep blue Aventurine dial with a frosted 904L steel case and blue leather strap. Notwithstanding the elegance of the model, this new introduction continues to embody the durable and high-performance standards expected from the robust Terra Nova field watch line.

Following the debut of the 904L steel and black gloss dial edition at Watches & Wonders in April 2025, this marks the second model in Bremont’s 40.5mm Jumping Hour range and the first time the brand has introduced Aventurine into the Terra Nova field watch collection. The result is a refined, contemporary timepiece designed to appeal to discerning collectors and enthusiasts.

Aventurine has long been admired for its depth and shimmer and each dial is cut using diamond tools and then patiently polished to a bright finish before being mounted to a metal backing plate for added strength and stability. The result is a dial of exceptional brilliance and colour.

Complementing the dial is Bremont’s first frosted 904L steel case. The surface treatment gives the steel case a shimmering brilliance resembling countless tiny diamond-like facets across the metal. The frosted finish enhances the way light interacts with the case, giving it a unique lustre and character. The result is a refined, elegant and contemporary case. that accentuates the Terra Nova’s modern geometry.

Since its launch in 2024, the extensive Terra Nova collection captures the rugged elegance, practicality, and timeless appeal of historic field watches. Designed and meticulously crafted, each model embodies legibility, durability and functional elegance. The clean highly legible dial of the new Aventurine Jumping Hour model embodies this spirit and at its core, the watch houses the Bremont calibre BC634, developed in partnership with Sellita under an exclusive two-year agreement, first unveiled within two distinctive models at Watches & Wonders 2025.

The 56-hour power reserve movement features a high-torque Jumping Hour complication, delivering an instantaneous hour change in under one tenth of a second. This technical precision is matched by the clean, balanced dial layout allowing the eye to naturally flow from left to right, ensuring optimal legibility and visual harmony.

The Jumping Hour complication has always fascinated me. It’s a connoisseur’s complication—mechanically sophisticated yet visually minimalist. This new Aventurine edition represents Bremont’s dedication to modern craftsmanship and our ability to surprise with new materials, finishes, and ideas. Dubai Watch Week felt like the perfect stage to unveil it—a celebration of horological creativity and the passion of collectors.” - Davide Cerrato, Bremont CEO.
