Product Overview
The movement is housed in a 43.5 mm diameter case with a curved lateral window in the case band at 8 o’clock. This three‐dimensional opening offers the observer a very special view of the Double Tourbillon system, showcasing the complexity and aesthetic qualities of this unique complication.
The polished conical arm and the flat black polish of the steel tourbillon bridge is one example of Greubel Forsey’s signature superlative hand finishing. The power reserve indicator at 2 o’clock features an innovative rotating disk displaying optimal remaining running time by means of a fixed red triangle instead of a conventional hand.
