Greubel Forsey describes its new Tourbillon 24 Secondes Architecture as a "city on the wrist" and they're not wrong. 354 parts come together to create an artful and complex structure that features a rotating 24-seconds tourbillon and a 90-hour power reserve. This is housed in an all-new case design for the company that measures 47mm in diameter and is constructed from lightweight titanium. There's also a synthetic sapphire crystal ring that surrounds the caseband that not only allows you to view the mechanics of the movement from all sides but also light to enter from all sides, casting shadows and illuminating the movement's various components.
11 examples of the watch will be produced this year and 18 watches will be produced annually until 2025 for a total run of 65 pieces.
