Bremont continues to develop its Terra Nova series and now presents one of the most visually powerful models so far — the Terra Nova 38 Jumping Hour Stealth Black. A watch that combines British design tradition with modern technology and an uncompromising all-black aesthetic.
A modern take on the jumping hour
The jumping-hour complication dates back to the early 1900s and the so-called montres à guichet. Here the hours and minutes are shown through windows — an hour window at 12, a minute window at 6 — for a clean and focused expression, complemented by a small running-seconds window. The hour change happens in a flash, in under a tenth of a second, thanks to the exclusively developed BC634 movement made in partnership with Sellita (built on a Sellita SW300 base with a proprietary jumping-hour module). It runs at 28,800 vibrations per hour with 29 jewels and a 56-hour power reserve, and the dial windows sit beneath three individual sapphire crystals. The central sweeping seconds hand runs over Bremont’s Wayfinder logo and is filled with green-emission Super-LumiNova — both playful and functional, with clear legibility in all light conditions.
Stealth black — tool feel with attitude
The case measures 38 mm and is made from 904L steel, known for its high resistance to corrosion. The whole watch is coated in black DLC (Diamond-Like Carbon), which gives a hard-wearing surface with clear presence. The combination of a cushion-shaped case, low profile (9.1 mm), and short lugs gives a distinct silhouette that stands out without feeling excessive. Water resistance is 30 metres. The design draws inspiration from early military and trench watches, but the interpretation is modern, technical, and confident.
Bracelet or Bund — two expressions
The model is offered either on a matching DLC-treated 904L steel bracelet with a folding clasp, or on a black leather Bund strap. The Bund strap recalls World War II pilot watches, where extra protection against cold and heat was crucial. For anyone who wants a more understated look, the Bund pad can be removed to leave a classic black leather strap, swapped easily via the quick-release pins.
A clear statement in the Terra Nova series
After earlier versions in bronze and steel sold out quickly — the design was named WatchPro UK’s Trend Watch of the Year 2025 — the Stealth Black takes a clear step toward a more dramatic and contemporary aesthetic. This is a field watch with a complication: robust enough for everyday use but with a technical twist that makes it extra interesting for collectors. Priced at around USD 5,650 on the bracelet and USD 5,200 on the Bund strap, it shows how Bremont keeps pushing the line forward.
