New Versions of the Bremont Terra Nova Jumping Hour, Including a New 35mm Size

Marking a pronounced design shift for the British watchmaker, Bremont released the bold Terra Nova Jumping Hour model in 2025. A field watch inspired by early 20^th-century military pocket watches and World War I trench watches, the Jumping Hour comes with two different displays: a 38mm montre à guichet-style watch with a covered dial and three small apertures or the more conventional and larger 40.5mm open-dial version with two offset apertures. During Geneva Watch Days, Bremont presents a new, compact 35mm case size, frosted case finishes and two vibrant new dial colours. 

A montre à guichet is defined as a watch with small apertures (guichets) instead of hands to read the time. The smaller 38mm Jumping Hour model adopted the protective grilles of yesteryear’s trench watches, covering the dial with three vertically and centrally aligned apertures to display the jumping hours at noon, the running seconds in a round aperture with the new Wayfinder compass logo in the centre and the minutes below. Following the inaugural bronze model, Bremont followed up with references in steel and black DLC.

The closed-dial Jumping Hour, available until today in a 38mm case, now comes in a compact 35mm cushion-shaped case with a slightly reduced height of 8.9mm, but retains its 30-metre depth rating. Instead of the three apertures of the larger models, the brushed steel plate covering the dial now has just two apertures for the jumping hours and minutes. The small seconds aperture has been eliminated and replaced with an engraved depiction of the Wayfinder compass.

Another difference is the reduction in inscriptions on the steel plate, which now features only “Bremont, London”. The jumping hours disc is white with black numerals treated with green-emission Super-LumiNova, while the minutes are printed in black; both windows are protected by sapphire crystal, with a magnifier over the hours. Available with a steel bracelet or a grey nubuck leather strap, both options come with a quick-release system.

There are also two limited editions, both with frosted cases but different dials. The 150-piece Jumping Hour Frosted has a frosted, slightly sparkling case and dial protector, highlighted by the thick, brightly polished bevel.  Sharing identical specifications to the regular 35mm steel models, the frosted model is even more minimalist and dispenses with the Wayfinder logo in the centre, the pointer under the minutes and the London inscription. In fact, the only information apart from the two apertures is a polished Bremont appliqué at 6 o’clock. This model is only available on the grey leather strap.

The second 200-piece limited edition is a more flamboyant 35mm Frosted Pink model with a frosted case and bezel and a hot pink lacquered dial with a sunray effect. With just two apertures for the hours and minutes, each with a white background and pink numerals, the Frosted Pink reference has a central seconds hand indicating a peripheral railway-style track, with applied silver stars and diamonds marking the even numerals. The watch is paired with a quick-release pink nubuck strap.

Another new non-limited 35mm reference, sharing the same layout as the Frosted Pink, has also been released, this time with a rich burgundy lacquered dial and applied dots and star markers on the periphery. Available on a strap or bracelet, the apertures have black grained backgrounds with white numerals. A nice upgrade, the two 35mm Frosted models and the burgundy dial have an increased water-resistance rating of 100 metres.

Alongside the new 35mm case size, Bremont is presenting its larger 40.5mm Jumping Hour model, with a new lacquered burgundy dial, available with a steel bracelet or strap. It retains its left-centred layout, with an aperture for the jumping hours at 9 o’clock flanked by the minutes window alongside the central seconds hand.

All the new watches have closed casebacks and are powered by the customised Sellita-based automatic calibre BC634, with high torque to ensure the jumping hours snap into place in less than 1/10 of a second. Beating at 4Hz, the movement delivers a robust 56-hour power reserve.

Prices are EUR 4,750 for the 35mm version with closed dial, EUR 5,400 for the frosted closed dial, EUR 5,100 for the frosted pink and EUR 4,200 for the two burgundy versions (35mm and 40.5mm). More information at bremont.com.
