Richard Mille RM 53-02 Tourbillon Sapphire

How A Dash Of Transparency Makes Even A Great Watch Better. Ten different pulleys guide the tiny steel cable and guarantee that the tension distribution is even, making this watch extremely shock-resistant. The transparent case allows you to admire the incredible movement from literally every angle. It takes 1,000 hours to craft one of these cases, on top of the four weeks required for the sapphire crystal to grow. While this watch is limited to only ten pieces, it is still an imposing amount given how challenging it is to make even a single one of them.  The RM53-01 Tourbillon Pablo Mac Donough was one of the highlights of the 2018 SIHH and one of Mille's best-loved watches of the year. It is fitted with a tourbillon and has a generous power reserve of 70-hours.
