Grönefeld

For the first time Bart and Tim decided to add a hinged hunter case back to one of their timepieces. This Grönefeld 1941 Principia Mandala is the first and only Grönefeld timepiece that has such a case back. The inside of the case back has an engraving with the images of Bart, Tim and their father Sjef.

Inspired by the Dutch Delta Works, The Horological Brothers have conceived their first sports utility watch, designed to cope with the perils of water ingress and shocks while still upholding the elevated standards of horology and traditional craftsmanship that are synonymous with the Grönefeld name.

The 1941 Grönograaf is the latest creation to be conceived in Oldenzaal. It is a classical chronograph, but consistent with the Grönefeld ethos, it incorporates several ingenious details.
