Every Greubel Forsey Tourbillon—like every timepiece made by the Swiss watchmakers—has a carefully crafted design with quality and artistic expression being essential. And, it isn’t limited to the elegant style reserved for formal wear. The Double Tourbillon 30 Degree Technique ref. DBL TRB 30 BLK, or the Tourbillon 24 Secondes Asymetrique ref. GF01, are beautiful examples of how an artistic, creative wristwatch can be worn casually, or for a formal occasion.
