The Short Answer
Bremont just expanded its Terra Nova Jumping Hour family at Geneva Watch Days 2026 with a new 35mm case size, a frosted steel dial, a burgundy lacquer edition, and a limited Frosted Pink variant. All of them run the brand's customized caliber BC634, an automatic Sellita-based movement with a jumping hour mechanism that snaps the hour disc forward in under a tenth of a second.
Pricing runs from $4,000 for the leather-strap Burgundy 35mm up to $5,150 for the 150-piece Frosted limited edition, with 100 meters of water resistance across the lineup. This is a genuine English watchmaker leaning into a real complication, not a dial gimmick borrowed for a press release.
The dual-aperture layout at 12 and 6 o'clock is the signature look of the Terra Nova Jumping Hour line, whichever dial finish you pick.

Who Bremont Actually Is
Bremont is a British watchmaker with an origin story rooted in tragedy, not marketing. Brothers Nick and Giles English founded the company in 2002 after a 1995 plane crash killed their father, an ex-RAF pilot with a doctorate in aeronautical engineering, and badly injured Nick.
The English brothers bought a flying airfield before they ever built a watch, and that aviation link has stayed central to the brand ever since. In 2021, Bremont opened The Wing, a 35,000-square-foot manufacturing facility near Henley-on-Thames that cost over £25 million and can produce up to 50,000 watches a year.
New Ownership, Same Direction
In 2023, Bill Ackman's Hellcat Acquisitions invested £48.4 million and became Bremont's majority owner. The English brothers stepped down from the board in April 2025 but stayed on as brand ambassadors, a fairly typical founder transition once outside capital takes control.
The Terra Nova Jumping Hour: What's Actually New
The Terra Nova Jumping Hour launched in 2025, and this 2026 expansion adds a smaller 35mm case alongside the existing 40.5mm size, plus three new dial treatments. The core layout stays consistent: a closed, brushed or frosted steel dial front with two sapphire-crystal apertures, one showing the jumping hour numeral, the other the running minutes.
The 904L steel case finishing and cushion silhouette carry over unchanged from the 40.5mm original.
That two-window face is what a jumping hour complication is built around: no hour hand at all, just a number that advances instantly once every sixty minutes. If the mechanism itself is new to you, it is worth reading how the complication actually works before deciding whether this specific execution is any good.
The Four New Variants
Alongside the standard 35mm closed-dial model, Bremont added a frosted-steel dial with a diamond-facet texture (limited to 150 pieces), a burgundy lacquered dial with a sunray finish and applied markers in both case sizes, and a Frosted Pink limited edition with a hot-pink sunray dial and alternating star and diamond markers, capped at 200 pieces.
The Movement: Caliber BC634
Caliber BC634 is a Bremont-customized automatic movement built with Sellita, running at 28,800 vibrations per hour (4Hz) with a 54-hour power reserve and 29 jewels. It uses a Glucydur balance wheel paired with an Anachron balance spring, both chosen for better resistance to temperature swings and magnetism than a standard alloy balance and spring.
The hour numeral has to fully clear its old position and lock into the new one in well under a second, which is why a dedicated jumping mechanism costs more to build than a simple hour hand.
Why a Sellita Base Instead of Full In-House
Bremont built its reputation on assembling and finishing movements in England around outsourced Swiss bases, rather than claiming a fully in-house caliber it does not have. That is an honest position for a brand this size, and it keeps prices well under what a true manufacture jumping hour movement would cost.
On the Wrist
At 35mm by 8.9mm, the new smaller Terra Nova Jumping Hour wears closer to a classic dress watch than the sportier 40.5mm original. That size drop matters more here than on most watches, since a dial with no hands at all reads differently depending on how much negative space surrounds the two apertures.
The 35mm case is aimed squarely at buyers who found the original Terra Nova Jumping Hour too large to wear as a daily dress watch.
The 904L steel bracelet and quick-release nubuck leather straps are interchangeable across the collection, a practical touch that lets one watch cover both a bracelet look and a dressier strap look without a trip to a jeweler.
The Frosted Finish Up Close
The frosted dial's diamond-facet texture catches light very differently from the smooth brushed original, and it is the version most likely to sell out first at 150 pieces.
The frosted texture is a genuine finishing technique, not a printed pattern, and it is part of why that variant costs more than the plain brushed steel version despite sharing the same case and movement.
Price and Positioning
| Variant | Case | Price |
|---|---|---|
| Terra Nova 35 (steel bracelet) | 35mm x 8.9mm | $4,800 |
| Terra Nova 35 (leather strap) | 35mm x 8.9mm | $4,550 |
| Terra Nova 35 Burgundy (steel/leather) | 35mm x 8.9mm | $4,300 / $4,000 |
| Terra Nova 40.5 Burgundy (steel/leather) | 40.5mm x 10.15mm | $4,300 / $4,000 |
| Terra Nova 35 Frosted (150 pieces) | 35mm x 10.3mm | $5,150 |
| Terra Nova 35 Frosted Pink (200 pieces) | 35mm x 8.9mm | $4,900 |
At $4,000 to $5,150, the Terra Nova Jumping Hour sits well below what a Swiss haute horlogerie jumping hour typically costs, while still delivering a genuine mechanical complication rather than a printed or disc-window gimmick.
Where It Sits Against Christopher Ward's Jumping Hour
Christopher Ward, another British brand, builds its own jumping hour watches at a noticeably lower price point using a similar outsourced-movement strategy. Bremont's version costs more but leans harder on finishing, aviation-adjacent brand story, and the option of a full steel bracelet rather than leather-only.
