A field watch with an uncommon mechanical complication.
The Terra Nova Jumping Hour pairs Bremont’s contemporary field-watch design with the distinctive BC634 jumping-hour calibre in a refined 904L steel case.
We carry it for its unusual time display, clean execution and blend of mechanical ingenuity with everyday wearability.
For clients who appreciate horological individuality and purposeful design, it is Bremont at its most inventive.
A jumping-hour calibre with a distinctly modern character.
The BC634AH is an exclusive high-torque automatic calibre developed for Bremont’s Terra Nova Jumping Hour. Its precisely jumping hour disc creates an instantaneous change of hour, while the central seconds hand and Super-LumiNova® detailing maintain clear, continuous legibility.
Servicing is handled through Bremont’s authorised service network, with specialist care to preserve the calibre’s precision and reliable performance.
The watch, by the number.
