Swiss luxury watch brand Richard Mille will donate a unique piece to Only Watch, the Yohan Blake Tourbillon Prototype, for the 5th edition of this exceptional charity auction held in Monaco. The proceeds from the auction will be for the Monegasque Association against Muscular Dystrophy.
The watch being donated is the Yohan Blake Tourbillon Prototype which Yohan Blake wore at the 2012 London Olympic Games where he won three medals and also at the Diamond League in Lausanne where he also won the 100m and became the third fastest sprinter of all time over this distance, beating his personal best. This Tourbillon Prototype in the colours of the Jamaican flag features a green flange and crown, yellow minute-markers and a yellow Velcro® strap that contrasts with the all white case. This caliber with 19 jewels and beating at 3Hz, has its base plate, bridges and balance cock made of grade 5 titanium.
The case of this prototype is made of an extremely rugged and light alloy called magnesium WE 54, one of the lightest metals used in construction and has excellent property retention capacities at elevated temperatures. After a long and delicate machining phase, theses alloys are given a new electro-plasma oxidation treatment called Miarox®, improving both the durability and scratch resistance of this alloy as well as its wear and corrosion properties.
