Did you know that…
- Bart’s first watchmovement was a small minute repeater movement developed together with Renaud et Papi in about 1991?
- Tim’s specialty are Tourbillons?
- Bart and Tim are third generation watchmakers dating back to 1912 when their great grandfather started out as watchmaker in Oldenzaal?
- Communication with Renau et Papi who develops the movement for Groenefeld is only in French?
- The first Groenefeld One Hertz watch had a construction mistake? The watch would run only when it was not wound, and when it was wound, the balance wheel would not spin? Luckily, this was an easy to fix mistake, and all they needed to do was replace one part.
- When a watchmaker is constructing a new movement, is would be better to construct it based on the front (where the dial will be) instead of the back? The reason being that construction mistakes could be avoided that way as the watchmaker and/or designer will immediately realize any mistakes, such as hands turning backwards, or crown setting mistakes, or other possible construction and design mistakes.
- The dial on the Parallax is held wth three screws? Usually, a dial is fixated with two copper feet. However, copper feet are soft and kind of weak. Grönefeld therefore decided to use three screws to hold the dial in place, and that is a really safe way to do it.
