Grönefeld 1941 Principia Automatic – Dutch Independent Watchmaking at Its Finest

The Grönefeld 1941 Principia Automatic Turquoise dial is a remarkable expression of independent haute horlogerie, handcrafted by the renowned Horological Brothers, Bart and Tim Grönefeld. Produced in extremely limited numbers, the Principia embodies meticulous finishing, exceptional mechanical engineering, and understated elegance.

This stunning 2023 example features a vibrant turquoise dial that beautifully contrasts with the refined 39.5 mm stainless steel case. The signature flame-blued steel hands and engraved crown bearing the Horological Brothers logo add distinctive character to this highly collectible timepiece.

At its heart is the in-house Grönefeld caliber G-06, an automatic movement designed, finished, and assembled entirely in-house. Delivering an impressive 56-hour power reserve, the movement is showcased through a sapphire crystal exhibition caseback, revealing the extraordinary level of hand-finishing for which Grönefeld is celebrated.

Finished with a luxurious hand-stitched blue-green python leather strap, this watch is presented in excellent pre-owned condition and includes its original presentation box and warranty papers.
