Greubel Forsey recently unveiled a new 8 piece limited edition piece with full sapphire case. In line with advancing technology, 100% sapphire cases have continued to permeate the high-end watchmaking world, with Greubel Forsey joining Richard Mille, Hublot, H. Moser, MB&F, Bell & Ross and others in the high dollar “sapphire case” club.
The sapphire case uses a 3-piece construction – bezel, middle and back, secured by long screws and nuts, which results in a 49.95mm x 17.15mm beast of a case that is a couple millimeters larger than the already sizeable regular Double Tourbillon 30°.
The manual winding movement of the Double Tourbillon 30° Technique comprises no less than 385 components. Four fast-rotating coaxial mainspring barrels visible under an embossed nickel-palladium finished gold cover at 10 o’clock provide 120 hours of power reserve. The 47.5 mm diameter case in white gold offers unprecedented views through the sapphire crystal and display back to the nickel-palladium finished German silver bridges with their spotting, polished bevels and frosted surfaces. Time is displayed with central hour and minute hands – with the hour indexes on a sapphire crystal ring – and sectorial indications for the small seconds and power reserve in white gold.
This bold endeavour is a showpiece in every regard, with the $1.1million price to go with it.
