GENEVA, Sept 9: His theories stretched the boundaries of space and time, but Albert Einstein himself favoured that hallmark of reliable timekeeping a Swiss watch that will be sold at auction next month.

The Longines wristwatch could fetch $20,000-30,000 when it goes under the hammer in New York on Oct 16, Geneva-based auctioneers Antiquorum said on Tuesday.

The 14-carat gold timepiece is unremarkable in its design, but the auctioneers hope its value will be exponentially boosted by the allure of its illustrious owner best known for the theory of relativity.

It was presented to Einstein by Edgar Magnin, celebrated Hollywood “rabbi to the stars”, at a gala luncheon in honour of the German-born physicist and Nobel laureate in Los Angeles in 1931. “It’s definitely for a different kind of collector,” one who specialises in Einstein memorabilia, said Antiquorum watch specialist Julien Schaerer.
