Blemont has unveiled two new surprise models in the 2025 Terra Nova lineup in the form of two variations of the intricate watches for Jump Hour. To match the current hot trends in Jump Hour Design, Terra Nova Jump Hour is available in two formats. One is 38mm bronze and the other is 40.5mm stainless steel. Both watches feature the same jump hour caliber, but the bronze has a more traditional layout, with dialless and simple openings, while the steel model has more traditional dials and seconds hand.
Traditional time and minutes hand is 2024, darling. Anyone in this year’s watch world seems to be embracing the dial-less look and abandoning the traditional way of communicating time by rotating your hands around the dial. It is a concept that Cartier led in the 1920s with Tank à Guichets. With this year’s reintroduction at Watches & Wonders, we set up a benchmark, and this complex trend is I’m here to stay in the near future. There have been several releases recently from Maen, Fears, Franck Muller, Chanel, and Gerald Charles, but no one has been astounded as this new product from the British brand Bremont, The Terra Nova Jumping Hour Collection.
Terra Nova Jumping Hour, creator of Blemont CEO Davide Cerrato, combines traditional aspects of Blemont’s typical design language with the Art Deco era of the 1920s and 1930s to replace traditional dial layouts with clean, easy-to-read, mechanically driven digital displays. The new collection consists of two different variations, limited edition stainless steel and bronze, both offering very different takes of jump hour style.
The Terra Nova Line takes inspiration from early 20th century trench watches and chooses a robust design, but incorporates more modern and thicker proportions, moving forward with Blemont’s new, somewhat controversial design language. Despite criticism, it’s fair to say that the brand doubles its vision and shows what it can do with Terranova. The new Jump Hour Collection is available in two variations in both familiar cushioning styles, but both are completely different in their own unique ways. The first is 38mm in diameter and is finished with brushed Capro Aluminum Bronze Alloy (Blemont CEO Davide Cerrato is known as the bronze alloy “Rolls-Royce”!), while the second is brushed and polished 904L stainless steel, slightly larger at 40.5mm.
The bronze model incorporates the traditional closed case jump hour style that appears in the “Montre A Gichet” fashion. It shows the time through a series of openings on the front of the case, and lacks any kind of dials like traditional watches like Cartier Tank Agichet. Stainless steel models show the jump hour mechanism in a more conservative way and hold the dial, so at a glance you don’t necessarily know that it’s a jump time clock.
Both cases have a bronze thickness of just 9.1mm, a 10.15mm thick, a 47mm lug with just 9.1mm copper in the lug, and the steel has an annoying 22mm lug width, rather than a 20mm bronze. Both models offer crown pushes and decorated stainless steel cases. This gives it a bronze-colored, 30 meters water resistance. This almost negates military tools-like aesthetics.
The Terra Nova Jumping Hour collection goes in different directions for both models, while the bronze model selects three openings to display the time at the top, a few minutes at the bottom, and a middle second window. The Seconds dial features the Bremont Compass Wayfinder logo. This is a subtle addition, but the hand is in the same color as the print, making it easier to read seconds, but this watch is unlikely to be used for timing purposes anyway. The dial section of the watch is still circular. This is still based on the main Terra Nova line, and it is probably cushion-like design, and it can’t help but think that there was a bit of cohesiveness if the front plate shape was changed to closely match the case shape.
However, the stainless steel models incorporate traditional dial layouts due to their design, making more visual sense. This allows you to look at the circular layout. The deep black dial is also described in neat detail with silver printed fine tracks, large center second hand and minimal dial text. The windows for hours and minutes sit at 9am (still 9am with this kind of dial? Is it certain? I’m not sure). This time it will be printed on Super Laminova – a troublesome decision given that the number per hour is only exposed for an hour (and the number per minute is only 5-10 minutes) – means that it means that it is defined. It’s not very practical.
Bremont partners with Sellita to offer an exclusive movement for both jump hour models. The Calibre BC634 is a modified Sellita movement with a high torque gearing system that allows the Hour Disc to jump to the next hour in under an hour. The BC634 is a self-winding movement with a 56-hour power reserve and features 29 gems and beats with 28,800 vibrations per hour. Blemont was able to ensure the exclusiveness of this move for two years. This means that you will see that the movement is open as it will be used in many other applications afterwards. The middle second, hour and minute disc placement means countless dial variations are possible, so expect to see complications of jump time for your future favorite microbrand.

Both models feature quick release straps and bracelet options, while the bronze model opts for brown leather straps with cream stitching and pin buckle closures. Or it features a fullcapro aluminum bronze alloy bracelet made up of Y-links and butterfly antlers. The stainless steel variation offers the same choice with black leather straps or stainless steel Y-link bracelets. Both are comfortable options, but I feel like I’m leaning well enough to the bracelet, especially for the bronze model, for a perfect look. As mentioned before, the stainless steel model has a 22mm lug width, which is a bit cumbersome, but Blemont offers a wide range of alternative straps as an optional accessory.
