Bremont Expands the Terra Nova Jumping Hour with a New 35mm Size and Fresh Variants

Bremont isn't a brand you normally associate with quirky displays and avant-garde time-reading. That changed in 2025 when they dropped the Terra Nova Jumping Hour, a field watch that pulls its visual language straight from early 20th-century military pocket watches and WWI trench watches. It was a sharp left turn, and it worked. Now they're doubling down.

The new wave of Terra Nova Jumping Hour variants brings something collectors have been asking for: a 35mm case. The original launched in 38mm, a size that suits a lot of wrists but not everyone's. Shrinking it down opens this watch to a much wider audience without changing what makes it interesting. There's also a covered dial option in the 38mm format, styled as a proper montre à guichet, where a hinged or sliding cover protects the display. That detail alone ties it back to the pocket watch heritage Bremont is clearly drawing on here.

Two display configurations, two case sizes, and a design that still looks like nothing else the brand has made. That's the headline.

What's Actually Different This Time

The 35mm addition is the most significant change. At that size, the Terra Nova Jumping Hour becomes a genuinely wearable daily watch for people with smaller wrists, and it also sits comfortably as a dress option rather than strictly a field piece. The proportions shift the whole character of the watch.

The core concept stays intact. Hours jump in a window display rather than sweep continuously on a dial, giving you an instant digital-style read of the time in a fully mechanical package. It's a format with real history, and Bremont's execution ties it to the military aesthetic through the case design, the crown guards, and the overall toughness of the build.

Who This Watch Is For

If you've been watching this line and the 38mm was just slightly too big, the 35mm is your answer. It's also worth pointing out that a 35mm jumping hour has some real crossover appeal. It's unusual enough to be a conversation piece, restrained enough to wear with a suit, and rugged enough in construction to handle daily life without drama.

The covered dial version is for the collector who wants the complete package. The montre à guichet format with a protective cover is pure theatre, in the best way. You flip the cover, read the time, close it again. There's a ritual to it that battery-powered watches simply can't replicate.

• Two case sizes: 38mm original and new 35mm option
• Two display styles: open dial and covered montre à guichet format
• Jumping hour display inspired by WWI military pocket watch design
• Field watch construction with crown protection
• Part of Bremont's broader Terra Nova collection, which represents a clear design shift for the brand

How It Stacks Up

Jumping hour watches sit in a specific niche. You've got historical references from brands like IWC and Cartier at the high end, and a handful of independents playing in this space at various price points. Bremont is landing somewhere in the middle, with the brand credibility and British manufacturing story behind it.

What sets the Terra Nova Jumping Hour apart from most of its peers is the deliberate historical framing. This isn't a jumping hour as a technical flex or a design exercise for its own sake. Bremont has built a coherent narrative around military history, and the watch earns its unusual display format because of that context. The covered dial version makes that argument even more convincingly.

The 35mm size also moves Bremont into territory where they don't have much existing competition within their own lineup. It's a smart expansion that doesn't dilute the original, it just makes it more accessible.

The Terra Nova Jumping Hour was already one of the more interesting things Bremont has done in years. These new versions suggest they're committed to the idea rather than treating it as a one-off experiment. That's encouraging. Keep an eye on where this line goes next.
