Greubel Forsey Tourbillon 24 Secondes Diamond Set Contemporain (In White Gold)

Introduced in 2014, this sparkling edition of Greubel Forsey Tourbillon 24 Secondes Contemporain timepiece opens the door to the maritime universe where our gaze drifts between the blued titanium ocean and the cloud layer of sparkling diamonds, illuminated by the circumlocutions of a Tourbillon 24 Secondes.

This timepiece is powered by the Tourbillon 24 Secondes inclined at 25°. Such an elaborate diamond- set movement is worthy of an equally splendid backdrop. Here, a white gold case is also set with diamonds on the bezel, also featuring baguette diamond set lugs.

The setting continues right up to the clasp, a volume of 9.71 carats in total. The original version of this timepiece was more contemporary: Its royal blue colour highlighted the Tourbillon 24 Secondes inclined at 25°. Here, the presence of invisible- set diamonds transforms this piece into a watchmaking sculpture.
