Today, we want to introduce a new watch manufacturer here. The horological brothers Bart and Tim Grönefeld are not new in the watchmaking world in the traditional sense, but this is our first article about their manufacture and their timepieces. The Grönefeld family has, in fact, a watchmaking history spanning over more than a century. And this legacy is now managed by the third generation. The Grönefeld brothers made it their mission to build elegant timepieces with surprising mechanisms and unique designs.
Almost three years after the release of their award winning 1941 Remontoire, Grönefeld is pleased to reveal their first automatically wound timepiece, the 1941 Principia.
The 1941 Principia borrows its name from Newton’s Philosophiæ Naturalis Principia Mathematica in which he adresses the foundation of classical mechanics.

Much consideration has been given to the dial design, which delivers readability and the watches aesthetic. Each version of the 1941 Principia is offered with an array of dials, all crafted in silver. There is a cream lacquered dial with roman numerals, a matt turquoise or light blue one with applied baton hour markers. Alternatively there are also rhodium plated or gold plated salmon dials available.
The extended Lancette hour and minute hands are flame-blued and include mirror-polished centres. In the lower portion of the dial is a small seconds display. A blue hand with a counterweight traverses the display with poise. At the top of the subdial on the cream lacquer dial, “60” is proclaimed in a subtle shade of orange. It is a patriotic reference to Bart and Tim’s country of birth, The Netherlands.

The 1941 Principia is housed in the company’s 1941 case. It is available in red or white gold as well as in stainless steel. The lugs are retained with hidden titanium screws and can be detached for remedial polishing or they can even be replaced.
Measuring 39.5 mm in diameter, with a restrained height of 10.5 mm, the 1941 case is beautifully balanced. It is also water-resistant up to 3 atm.

When the motion of the wearer’s wrist causes an oscillating weight to rotate under gravity, the watch is automatically wound.  as is the 1941 Principia. But gravity can also make watches run fast or slow. To mitigate the influence of this, the Grönefeld 1941 Principia Automatic is fitted with a free-sprung hairspring.
The automatic movement consists of 226 parts, works at 21.600 vibrations per hour and provides a power-reserve of 56 hours.

The 1941 Principia Automatic comes with a leather strap. Customers have a choice of different leathers and colors.
