1941 Principia automatic
Turquoise dial

The Grönefeld 1941 Principia Automatic is offered with an array of dials, all crafted in solid sterling silver. The would-be wearer can choose from a cream lacquered dial with roman numerals, a refreshing matt turquoise or light blue dial with polished applied baton hour markers. Alternatively, the company's rhodium plated or gold plated salmon dials are also available.

The Principia is housed in the company's 1941 case. Named after the year their father Sjef was born, the 1941 case exudes grace from every angle. It is available in red gold, white gold or stainless steel. A sapphire case back has been fitted to confer a spectacular view on the extensively hand finished movement with their well known stainless steel bridges and a 22K solid gold oscillating weight.

Each Grönefeld 1941 Principia is delivered with a high quality, double axis, watch-winder. The gracious motion of the polished stainless steel rings is a delight for the eye and compliments the high quality automatic movement.

A movement for connoisseurs

Just as the award winning 1941 Remontoire, Bart and Tim Grönefeld want the 1941 Principia again to appeal to the most discerning watch collectors. It was therefore imperative that the movement was befitting of such a timepiece. The stainless-steel bridges replicate the facades of the Dutch houses, termed 'bell gables', once again, referencing the homeland of the Horological Brothers. The bridges are hand-bevelled, evincing a brilliant gleam and have their jewels set in gold chatons.

The 1941 Principia Automatic is fitted with a 22-karat solid red gold monobloc rotor. The eye-catching oscillating weight is extensively decorated by hand and turns on a ceramic ball bearing, preventing wear and eliminating the need for lubrication.This movement includes a balance wheel, with white gold timing screws, and is equipped with a reliable free-sprung hairspring.

Each movement is finished and assembled by hand. To emphasize the manual labour involved a gold plate, engraved with an individual number, is applied to the movement.
