McLaren has signed Richard Mille as its new watch sponsor, in the wake of its parting of ways with long-time backer TAG Heuer at the end of last season.
The Woking-based outfit had been with TAG Heuer for 30 years, but the Swiss company has moved across to Red Bull and taken naming rights to that team's engines.
Now, Richard Mille has concluded a 10-year deal to join McLaren, which will mean Fernando Alonso and Jenson Button will wear its watches.
McLaren chairman Ron Dennis said: "A 10-year partnership with McLaren underlines our shared belief in the value of long-term agreements, and the benefits that can be derived from growing and developing together.
"The two brands share a distinct common DNA: a passion for design, technology and aesthetics, and I'm excited about the great work we can achieve together over the next 10 years."
Mille himself said: "The chance to partner with McLaren is particularly timely: we've been evaluating Formula 1 on a restricted basis for several years, but this opportunity has enabled us to engage in a deeper, more meaningful way, with proper focus and effort directed on a major team."
Richard Mille is no stranger to F1 sponsorship, having previously backed the Lotus team as well as supporting the late Jules Bianchi.
