The year 2026 marks a historic milestone: the 250th anniversary of the United States. To celebrate this landmark semiquincentennial, British watchmaker Bremont has released a dedicated limited-edition timepiece rooted in exploration, mechanical ingenuity, and transatlantic heritage: the Bremont Terra Nova 40.5mm Jumping Hour 1776.
Priced at £3750, this commemorative release takes the rugged, early 20th-century field watch silhouette of the Terra Nova collection and elevates it with a classic horological complication: the jumping hour.
Limited to just 250 pieces worldwide, it represents a thoughtful, artistic crossover between military pocket watch aesthetics and contemporary independent watchmaking.
A Cushion-Shaped Canvas with Historic Details
The Terra Nova collection is widely recognized for its geometric 904L stainless steel cushion case—a modern interpretation of turn-of-the-century trench and pocket watches. At 40.5mm in diameter, the case maintains a slim, ergonomic profile featuring shortened lugs that allow it to sit comfortably on a wide variety of wrist sizes.
* Case Geometry: 40.5mm Cushion-Shaped 904L Stainless Steel
* Dial Finish: Deep blue grained texture with embossed "1776" inscription
* Complications: Roulette-style jump hour window at 9 o'clock
* Luminescence: Full Super-LumiNova® central seconds & applied indices
The dial is where this edition truly distinguishes itself. Rendered in a rich, textured deep blue, the surface displays a subtle “1776” inscription referencing the year of the Declaration of Independence.
The hour is read through a roulette-style jump aperture at 9 o’clock, complemented by a central minutes display and a central running seconds hand finished entirely in Super-LumiNova. A silver star motif subtly runs through the minute track, while bold red triangular accents at 3 and 9 o’clock frame the layout.
The Calibre BC634AH Jumping Hour
Beating beneath the dial is the exclusive Calibre BC634AH, developed for Bremont in close collaboration with movement specialist Sellita.
Mechanical jumping hour complications require careful power management, storing energy throughout the hour to instantly click the hour disc forward in a fraction of a second without destabilizing amplitude.
“The BC634AH movement balances mechanical ingenuity with everyday resilience, incorporating a Glucydur balance wheel, an Anachron balance spring, and a Nivaflex mainspring to deliver consistent precision.”
Operating at a frequency of 28,800 vibrations per hour (4Hz) across 29 jewels, the automatic movement delivers a dependable 56-hour power reserve.
It provides a highly readable, engaging alternative to standard three-hand displays, bridging vintage mechanical charm with effortless legibility.
Commemorative Caseback & On-Wrist Presence
Turning the steel case over reveals a heavily detailed, solid caseback. It features an engraving of an American bald eagle in full flight above a stars-and-stripes field, bordered by stars and individually stamped with its edition number out of 250.
| Specification | Detail |
| Movement Engine | Exclusive Bremont BC634AH Automatic (56-Hour Reserve) |
| Water Resistance | 10 ATM / 100 Meters / 330 Feet |
| Strap Hardware | Blue textured leather with steel pin buckle |
| Global Edition | 250 individually numbered pieces |
Despite its delicate jumping hour mechanism, the watch maintains real-world durability with 100 meters of water resistance.
Fitted to a matching blue textured leather strap that highlights the dial’s deep tones, the Bremont Terra Nova 40.5mm Jumping Hour 1776 is a standout £3750 release that seamlessly bridges British horological design with American historic celebration.
