Eric Clapton’s Crazy Doc Rolex may fetch US$1.6 million at auction – plus 4 more highlights from Phillips’ Geneva Watch Auction: XV, including Patek Philippes and an Audemars Piguet

Eric Clapton’s Rolex Crazy Doc is set to go under the hammer at the Geneva Watch Auction: XV. Taking place on May 7 and 8 through Phillips in association with Bacs & Russo, the auction follows on from the Royal Oak 50th anniversary sale taking place a day prior.

Here are five of the highlights we’re most excited about …

1. Rolex 6239 Cosmograph Crazy Doc

Clapton, 77, is a three-time inductee of the rock ‘n’ roll Hall of Fame and has an estimated net worth of US$450 million, according to Celebrity Net Worth. He’s kept a relatively low profile throughout his career, but the known watch aficionado boasts a collection most museums would envy.

The Crazy Doc formerly in the Tears in Heaven singer’s possession was previously sold at auction in 2003. The 18 karat yellow gold 6239 timepiece is thought to be the only one of its kind with a pulsation scale and is expected to fetch up to US$1.6 million. The pulsation scale was first introduced in the 1930s, when doctors would start the chronograph and use it to count the beats of a patient’s heart.

2. Rolex Paul Newman 6241 Daytona

Manufactured between 1966 and 1969, this Rolex Paul Newman 6241 – known as The John Player Special – is thought to be one of the rarest Daytonas in existence, as it’s thought that just 300 yellow gold iterations of the timepiece were manufactured.

The black and gold dial is a nod to John Player – the cigarette maker and former Formula One Lotus team sponsor – and the graphics splashed over the racing car. It is estimated to fetch up to US$1.5 million.

3. Patek Philippe 1503 stainless steel
