The Grönefeld 1941 Quadrivium Tantalum brings four sophisticated complications together in an extraordinary expression of independent haute horlogerie. Housed in the Maison’s signature 1941 case, the 40 mm tantalum watch combines a one-minute flying tourbillon, 7.5-second remontoire, central jumping seconds, and power reserve indication in a completely new hand-wound movement. The finely frosted dial is framed by hand-beveled stainless steel elements and polished, multi-faceted white gold hour markers, while heat-blued steel hands add traditional watchmaking character. Each indication has a deliberate place on the dial, from the hours and minutes at 2 o’clock to the flying tourbillon at 6 o’clock and the visible remontoire governor at 9 o’clock, creating a compelling display of mechanical watchmaking.

A limited edition of 28 pieces
At the heart of the 1941 Quadrivium is Grönefeld Calibre G-09, a 473-component movement featuring two coaxially arranged barrels connected in series for a balanced 50-hour power reserve. The dedicated dead-seconds mechanism allows the central seconds hand to advance in precise one-second intervals, while the flying tourbillon and exposed remontoire reveal the sophisticated mechanics at work. Through the sapphire exhibition caseback, collectors can admire extensive hand-finishing, including beveled stainless steel bridges, micro-blasted and circular-grained surfaces, and a ruthenium-plated main plate. Limited to just 28 pieces in tantalum, the 1941 Quadrivium Tantalum is a rare luxury watch for collectors seeking advanced complications, traditional hand-finishing, and the distinctive independent watchmaking of Grönefeld.
