DALLAS, TX.- In 1927, a Rolex Oyster watch was proven to be waterproof when England’s Mercedes Gleitze wore it while swimming across the English Channel, after which it remained in perfect working condition. The event helped fulfill founder Hans Wilsdorf’s dream of creating wristwatches that were not only elegant, but also functional and reliable.

More than four decades later, Dutch swimmer and coach Corrie Ebbelaar set a record for the fastest cross-channel swim when she made it from England to France in 10 hours, 43 minutes — shattering Greta Anderson’s previous standard by nearly three hours.

A Rolex Important Ref. 5513 Submariner Presentation Watch inscribed to Ebbelaar is a magnificent and unique trophy that will be among the top attractions in Heritage’s Watches & Fine Timepieces Signature® Auction April 24. The back is inscribed “Corrie Ebbelaar To Commemorate The Fastest Cross-Channel Swim In 1971, Rolex London, England - France 10 Hours 43 Minutes, 5-9-71.” The inclusion of “Rolex London” solidifies the direct link to the brand designating this watch for Ebbelaar after her unprecedented accomplishment.

“Rolex is among the finest watchmakers in the world, often given to celebrate any number of accomplishments,” says Jim Wolf, Heritage’s Director of Watches and Fine Timepieces. “The fact that ‘Rolex London’ is included in the presentation engraving would imply that they were hands-on with this special-order watch.”

Also in play is a Rolex, Very Fine “Big Red” Oyster Cosmograph Daytona, Ref. 6265/6263. circa 1979, with aging expected on a 47-year-old watch but no replacement parts. What sets this exceptional watch apart is the red “DAYTONA” lettering that arcs over the lowest subdial, in a larger typeface than often appears, a style coveted by serious Rolex collectors.

A Rolex Oyster Perpetual Date DeepSea Full Set, Ref. 136668LB is a striking example for the reference, which is the first sold 18k gold professional watch in the DeepSea collection, debuting at Watches & Wonders in 2024. It maintains the extreme technical capabilities of the line while introducing a level of opulence previously reserved for the Submariner or Yacht-Master. Despite its luxury material, it maintains a professional depth rating of 3,900 meters (12,800 feet), while commanding attention through the bold contrast between the radiant yellow gold and the electric blue lacquer dial and ceramic bezel.

A L. Leroy Osmior Tourbillon 18K Rose Gold Automatic Regulator Wristwatch No. 1793 Ref. LL106 is a high-horology timepiece featuring a rare chronometer-certified automatic tourbillon movement with a regulator-style dial. This specific reference, No. 1793, is recognized for its “Besançon Viper’s Head” certification — a prestigious mark of precision from the Besançon National Observatory.

The Vacheron Constantin Dual Time 18k Full Set, Ref. 7920V is a 41mm luxury sports watch designed for travelers and features a second time zone, a day/night indicator and a pointer date. It is one of those rare pieces that combines beauty and pedigree with a certain nonchalance about the lifestyle of its wearer. Despite its luxury finishing, it remains a robust sports watch with 150-meter water resistance and significant anti-magnetic protection.

A Chaumet Jump Hour, 18k Yellow Gold, Ref. 10A features an avant-garde design that was introduced in 1992. During the period in which it was created, Chaumet commissioned François Paul Journe to produce complicated timepieces for the brand; this exceptional watch was one of the models he had a hand in creating.
