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.
