Bremont focuses purely on beautifully made mechanical movements and every watch in our core collection has passed each of the rigorous precision tests necessary for the ISO 3159 chronometer designation.

Proudly made in the UK
Great Britain has a wonderful history when it comes to watch making and has probably been the home to more advances in horology than any other nation. Bremont is determined to play a pivotal role in the reinvigoration of this industry on British shores and as a result, Bremont manufactures parts at its Parts Manufacturing Facility and every Bremont is hand-build and tested before leaving the Henley-on-Thames workshop.
Description
The Terra Nova Jumping Hour in 904L stainless steel brings a refined and contemporary twist to Bremont’s modern field watch design. Housed in a polished and brushed 40.5mm 904L stainless steel cushion-shaped Terra Nova case, it blends vintage inspiration with cutting-edge mechanics. Its gloss black dial features clean, offset apertures for the hour and minute displays, offering a left-to-right flow that enhances both balance and readability.
At its core is the exclusive BC634 Jumping Hour calibre. This high-torque movement ensures a sharp, precise jump of the hour disc, while the central seconds hand – applied with the latest generation Super-LumiNova® – delivers continuous clarity, even in low light. Finished with applied markers, a detailed minute track and luminous accents, the watch offers exceptional legibility and a distinctive, high-contrast aesthetic.
Available on either a 904L stainless steel Terra Nova bracelet or black gradient leather strap, the Terra Nova Jumping Hour is a clean, elegant execution of a rare complication – made for those who appreciate mechanical ingenuity and everyday versatility.
