The case and bezel draw on both Carbon TPT and 5N red gold — a combination that keeps weight in check while lending the piece a distinctly architectural presence on the wrist. A sapphire crystal sits above the grey dial, while a transparent sapphire case back opens the view directly onto the manual-wind RM 21-01 caliber running beneath.\u003c\/p\u003e\u003cp\u003eThat caliber carries more than a tourbillon alone. A power reserve readout, torque indicator, and function selector all share the movement architecture, giving the wearer a layered read on the watch's mechanical state at any given moment. Approximately 70 hours of power reserve and a screw-locked crown round out the functional picture, alongside 50 metres of water resistance.\u003c\/p\u003e\u003cp\u003eThe rubber strap with a red gold folding clasp secures the generous 42.68 x 50.12 mm case and brings the overall composition together — technical materials up top, a refined closure at the wrist. For collectors drawn to tourbillon watches that lead with engineering rather than ornamentation, the RM 21-01 makes a compelling case.\u003c\/p\u003e","brand":"It's That Time","offers":[{"title":"Default Title","offer_id":49920030671077,"sku":null,"price":1522340.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/5600\/7653\/files\/Richard-Mille-Tourbillon-Aerodyne-RM-21-01.webp?v=1782917611","url":"https:\/\/itsthattimenyc.com\/products\/richard-mille-tourbillon-aerodyne-rm-21-01-watch","provider":"It's That Time ","version":"1.0","type":"link"}
