1941 Principia

Grönefeld 2019

Unisex

Dutch brothers Tim and Bart Grönefeld present their very first watch to be driven by an automatic calibre, which they have housed inside the classical forms of a 39.5mm case in steel, mounted on a python strap, with a silver turquoise dial circled by large hour markers and swept by flame-blued hands. This handsome exterior finds its match in the precision of the movement, a robust mechanism intended for daily wear. So as to offset the positional errors caused by the unwanted effects of gravity, the 1941 Principia is fitted with a free-sprung balance spring, which can be admired through the case's sapphire back. Beneath the red gold oscillating weight, which turns on a ceramic ball bearing, the spectacle of the mechanism in motion is there to see, to the delight of any connoisseur.
