The biennial Only Watch auction benefits charity as well as offering luxury watch maisons an opportunity to showcase one-of-a-kind models. The auction debuted in 2005. All proceeds will go towards research on Duchenne muscular dystrophy.

This year, the auction features 49 one-off models from heritage maisons, including Patek Philippe,Audemars Piguet, Breguet, Boucheron, Harry Winston, and contemporary independent brands, such as MB&F, Urwerk and MCT.

The auction is scheduled to open on November 11 to kick off Christie’s autumn Geneva watch auction week. However, the watches will be touring around the world starting September 27 at the Monaco Yacht show and will be coming to Hong Kong on October 23 and 24.

The Only Watch auction is certainly exciting for watch collectors. We’ve highlighted some of the most interesting pieces that you need to know about before heading to the auction.

Patek Philippe

The maison’s watches have been crowned the top lot at almost all Only Watch auctions. The steel Patek 5016 sold for a record of 7.3 million CHF (HK$59.2 million) at the 2015 Only Watch. The new Reference 5208 Triple Complication wristwatch, created exclusively for the auction, is the first and only version of this watch produced in titanium. The watch also comes with a rare experience for the top bidder. The lucky owner will visit Patek Philippe’s workshops and museum, and have a private lunch with the brand’s president, Thierry Stern.

Audemars Piguet

The unique Royal Oak Perpetual Calendar rendered in black ceramic features the brand’s signature Grand Tapisserie dial matched with an orange-tinted photo realistic moon.

The Reference 7715 features a silvered gold dial with Clous de Paris motif. It’s equipped with a self-winding movement and a perpetual calendar. The 18ct yellow gold case measures 39mm in diameter.
