Officine Panerai has designed a limited edition watch – The Radiomir Regatta – in conjunction with the sixth edition of Panerai Classic Yachts Challenge, an international circuit of regattas reserved for vintage and classic sailing boats. With just 500 units set for production, the Radiomir Regatta features a split-seconds chronograph with a 1/8th second foudroyante function and an express scale in knots for the calculation of the average speed of the vessel.

Other features of the timepiece includes 47mm brushed titanium case, “OP” crown, Panerai OP XXI caliber (automatic mechanical), 1/8th second counter at 9’oclock, water resistant at 100 meters and leather strap with brushed titanium buckle. Among the more than 500 vintage boats taking part in the Panerai Classic Yacht Challenge regattas, 2010 will also see the debut of Eilean, the Bermudan ketch built in 1936 in the legendary Scottish Fife boatyards, which was purchased and painstakingly restored by Officine Panerai, as part its commitment to safeguarding and promoting classic yachting.
