1941 Principia Automatic Light Blue

BHD 19,600.000
by Gronefeld
Description

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 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.
