Terra Nova Jumping Hour in steel, Bremont’s modern guichet lands
Bremont is adding a steel $5,100 Jumping Hour to the Terra Nova line, and it is a smart move. The bronze limited edition sold out. This new version keeps the same clean guichet layout and brings it into 904L steel with everyday wear in mind.
The Terra Nova case is a compact 38 mm cushion with short lugs. It wears flat, has a low profile, and looks like a field watch that took a trip through a design studio. Under the closed dial sit three windows, hours at 12, minutes at 6, and a central running seconds aperture that reads like a tiny compass. It is minimal and legible, and it gives the watch a calm, instrument feel.
Inside is the new BC634, developed with Sellita. The hour jump is sharp and instantaneous, under a tenth of a second. Specs are solid. You get 29 jewels, a 4 Hz rate, and a 56 hour power reserve. The case is 904L steel with brushed and polished surfaces and a decorated steel back. Water resistance is 3 ATM. This is a dressy field watch, not a diver, so that rating fits the brief.
Bremont is leaning into the British tool watch story here. The Terra Nova aesthetic nods to early 20th century military pocket watches, but the presentation is clean and current. The CEO, Davide Cerrato, called the first Jumping Hour a hit and said the steel model is not limited. That should make fans happy. The bronze was hard to find. This one will be easier to get.
The watch ships on either a brushed and polished 904L steel bracelet or a brown nubuck strap with cream box stitch. Both are quick release. Lug width is 20 mm, so strap swaps will be easy. The head weight is listed at 66 g, which is light for steel and should make the 38 mm case feel balanced.
Jump hours can get fussy. This one does not. The windows are crisp. The typography is straightforward. The seconds aperture adds motion without clutter. Bremont avoided a date window, which keeps the dial calm. The whole thing reads like a small tool made for daily use.
If you liked the bronze but wanted something you could beat up a little, this is the one. The Terra Nova Jumping Hour in steel brings the complication into a tough, compact case with a versatile look. It is not limited, it has a real movement story, and it avoids the bloat that hits a lot of modern field watches.
If you are a Terra Nova fan, this is the cleanest expression yet. If you are jumping hour curious, this is a friendly way in.
