Bespoke Dials
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.
The words ‘engine turned’ might suggest that a computer-aided machine is used to make the patterns, but nothing is further from the truth. The dials are actually made on a century old machine. Every decorative line is made at very slow speed by deft hand and the skilful precision of a well-trained eye. It actually takes a few days of painstaking and patient effort to produce just one guilloché dial. Bespoke series are available in a Stainless Steel, Red Gold or White Gold case.
After the launch in 2016 the 1941 Remontoire has been awarded 5 times! In November 2016 Grönefeld won again the prestigious Grand Prix d'Horlogerie de Genève award. This time the prize they’ve won was for the best watch in the “Mens Watch” category.
A movement for purists
From the outset, Bart and Tim always envisaged the Grönefeld 1941 Remontoire as a watch intended to appeal to the most discerning of watch collectors. It was therefore imperative that the movement was befitting of such a timepiece, appealing to the exacting requirements of purists. The stainless steel bridges replicate the facades of the Dutch houses, termed 'bell gables' and reference the homeland of the Horological Brothers, Bart and Tim. The bridges are hand-beveled, evincing a brilliant gleam, while the centres deliver a sublime contrast with their micro-blasted surfaces, adorned with relief engraving.
The new 5-arm, double spoke gear train wheels exhibit a contemporary character, but their circular grained surfaces pay due reverence to fine watchmaking tradition. The movement includes a balance wheel with white gold timing screws and is equipped with a free-sprung over-coil hairspring with triangular stud. Gold chatons stand testament to the no-compromise specification of this movement whilst mirror polished screws feature chamfered rims and slots. Numerous surfaces glisten, courtesy of mirror-polishing which has been patiently executed by time-served hands. The inventory of different surface decorations will sate the desires of any purist and include snailed, grained, spotted and frosted surfaces.
