Best Origin Story

Great watches tell a story and the Richard Mille Talisman Origine comes with a great tale.

Lot 51. Richard Mille: Talisman Origine

A millennia ago (or more accurately, once upon a lime), in a long-since vanished society where mechanics, craftsmanship and spirituality were united, this fascinating object emerged.

Discovered in the heart of the Swiss mountains, this pendant was imprisoned for an eternity in its wooden receptacle. Nicknamed “Talisman Origine” by the research teams, this mysterious golden relic certainly encapsulated the know-how of an old Swiss tribe.

Richard Mille Talisman Origine

Some Unique Pieces are more ‘unique than others

The Only Watch auction is exclusively unique piece watches, but while most are unique variations of existing (or soon-to-exist) models, a couple of brands, sorry, make that three brands, have taken ‘unique’ literally and created true one-offs.

Lot 60. Urwerk: Space-Time Blade

Urwerk didn’t simply create the Space-Time Blade as a sensational one-off digital clock, they had the manufacturer of the Nixie tubes develop over-sized tubes with numerals in the Urwerk font and with many more layers and complexity. It is also worth noting for those that relate Nixie tubes to retro displays, NASA ordered a clock from the same Nixie tube manufacturer Urwerk used because Nixie tubes can refresh much faster than any other display – that’s essential when you are counting 1/1000ths of a second.

Urwerk embarks on a new groundbreaking journey, redefining the very essence of time through a fresh and captivating approach. To materialize this extraordinary vision, the expertise of talented craftsman Dalibor Farny has been enlisted.  Science-Fiction and Time telling meet in a glowing magic.

Let the digits of light guide you through the Spacetime continuum, as this remarkable glass column illuminates not only the hours, minutes, and seconds but also kilometers depicting our smooth Earth travel.

Urwerk Space-Time Blade

Case: Glass capsule set on a bronze pedestal
Caliber: Urwerk concept
