For the moment we can’t take new orders until further notice. We are now processing the overwhelming amount of reservations we’ve received after the launch of our 1969 DeltaWorks and 1941 Grönograaf. Thank you for your patience and understanding.
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.
An automatic tourbillon movement ensures the mainspring is optimally wound, resulting in less variation in the rate of the movement. In normal use, the wearer does not need to operate the crown. A self-winding movement confers convenience, making it ideal for daily use.
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.
The time-consuming creation of each movement means that production will be limited to only 10 examples of the Grönefeld 1941 Decennium Tourbillon.

Despite embracing a new means of powering its latest watch, purists can be rest assured that Grönefeld's exalted standards of finish prevail. The stainless-steel bridges replicate the facades of the Dutch houses, termed 'bell gables'. They are hand-bevelled, evincing a brilliant gleam. The centres deliver a sublime contrast with their micro-blasted surfaces and are adorned with relief engraving.
The cage of the flying tourbillon, a tourbillon without an upper bridge, is made of stainless steel. The Horological Brothers use stainless steel for the cage and the aforementioned bridges because it is not liable to corrosion and, as such, proffers lasting benefits to the owner. Working with stainless steel requires great patience, but Bart and Tim believe the end result substantiates the time expended.
The 5-arm, double spoke gear train wheels exhibit a contemporary character with their circular grained surfaces paying 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. In addition, the mirror polished screws feature chamfered rims and slots. Numerous surfaces gleam, courtesy of the mirror-polishing which has been patiently executed by time-served hands. The inventory of different decorations includes snailed, grained, spotted and frosted surfaces, indulging the desires of purists.
