Swiss luxury watchmaker Panerai has unveiled the Radiomir 1940 Minute Repeater Carillon Tourbillon GMT, a piece distinguished by its rare double minute repeater mechanism, which can be set to chime the local time or a second time zone. The chiming function is activated by a push-piece at 8 o'clock, executed by three hammers striking three gongs that are fixed to the movement and the case. The watch's new in-house movement is Caliber P.2005/MR, a hand-wound, skeletonized caliber outfitted with a high-end minute repeater mechanism, as well as Panerai's hallmark tourbillon regulator. Starting at $395,000, the watch can only be made to order. Learn more about the Radiomir 1940 Minute Repeater Carillon Tourbillon GMT at Panerai.com.
