1941 Remontoire Constant Force RG

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 35 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.

The time-consuming creation of each movement means that production will be limited to only 188 Remontoire movements, each with its own unique serial number, offered in a choice of case material and dial variants.

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.
