1969 DeltaWorks

The Horological Brothers are proud of their heritage as well as the nation they call home, the Netherlands. Inspired by the Dutch ‘Delta Works’, Bart and Tim have conceived their first sports utility watch, the aptly named 1969 DeltaWorks which also references the year Bart was born.

The model is 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.

When designing this watch, Bart & Tim wanted to produce a model that indulged purists with a remarkable choice of colours and styles. The 1969 DeltaWorks is available with 3 different dial designs/colours, 5 different strap options and, finally, a choice of stainless steel inserts or colour-coordinated FKM rubber-clad inserts.

Please be aware that the inserts cannot be changed after a confirmed order.

1941 Grönograaf

While Grönefeld produced a number of different watches endowed with a variety of complications, it had never made a chronograph… until now.

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.

The ‘Premiere Edition’ will be encased in the rare metal tantalum and limited to just 25 pieces. Thereafter, Grönefeld will release 188 pieces in stainless steel.

This 1941 Grönograaf is the distillation of three generations of watchmaking know-how, of the professional journeys of both Horological Brothers and the manifestation of their extraordinary passion for horology.

1941 Principia

The Grönefeld 1941 Principia Automatic is offered with an array of dials, all crafted in solid sterling silver. One can choose from a cream lacquered dial with roman numerals, a refreshing matt turquoise, a light blue, a rhodium plated or a salmon dial with batton hour markers.

Decennium Tourbillon

To celebrate the company's 10th anniversary, Grönefeld has unveiled the '1941 Decennium Tourbillon'. This timepiece is endowed with an array of features, designed to indulge the desires of watch connoisseurs.

The automatic tourbillon movement is fitted with a 22-carat solid red gold monobloc rotor. The rotor is completely hand finished and turns on a ceramic ball bearing, preventing wear and eliminating the need for lubrication.

Measuring 39.5mm in diameter, with a restrained height of 10.5mm, the platinum 1941 case is the epitome of elegance, courtesy of its discreet mien.

This is a limited edition of 10 pieces only.

1941 Remontoire

The Grönefeld 1941 Remontoire features an eight seconds constant force mechanism, ensuring the force serving the balance wheel does not wane. From the mainspring being fully wound to the last minute of the 36 hours of power reserve, when the stop works intervenes, the force never fluctuates. The result is that the amplitude and rate remain consistent, leading to superior precision.

After the launch in 2016 the 1941 Remontoire has been awarded 5 times! In November 2016 Grönefeld won again the prestigious GPHG award. This time the prize they’ve won was for the best watch in the “Mens Watch” category.

Bespoke Watches

Grönefeld is able to offer a vast choice of coloured and patterned dials. The dials are engine-turned, sometimes referred to as guilloché dials. This process confers each dial with its own unique appearance. To augment the allure of the engine-turned patterns, another even more exclusive technique can be applied, enamelling. The colourful and transparent enamel is applied to the dial surface to bestow a profound depth and lustre to the guilloché patterns.

Parallax Tourbillon

The name ‘Parallax’ is derived from the precision conferred with the legibility of the central seconds hand. Parallax is defined as the apparent change in position of an object when the observer changes his own position. In order to mitigate the possibility of error due to parallax when viewing the seconds hand from an angle, the hand is exceptionally close to the outer chapter ring, marked with neat seconds indices. Additionally, the one-armed balance wheel bridge always runs parallel to the central seconds hand.

The Grönefeld Parallax Tourbillon was awarded the prestigious Grand Prix d'Horlogerie de Genève for the best watch in the tourbillon categorie.

1896 One Hertz

It features a beautiful solid silver dial and an entirely exclusive and unique movement with stainless steel bridges and exceptional finishing. Historically, an independent jumping seconds denoted superlative accuracy and so was a highly respected complication. Its popularity faded in the 1970s and 80s with the dominance of quartz movements, which stepped in full seconds. Mechanical movements soon became distinguished by a smooth, sweeping seconds hand. However, with their One Hertz,
