In 2016 Zadok Jewelers celebrated 40 Years, and what better way to celebrate than with a limited-edition timepiece from one of the world's most esteemed watchmakers?

Ulysse Nardin is producing 40 Marine Chronometer watches - yes, you can be one of only 40 individuals in the world to own one - to mark Zadok's four decades in business, and it's a 43mm beauty. Start with the midnight blue dial, then go to the 18-carat gold details, and you have understated elegance on your wrist. It has an open caseback, the better to admire its mechanical splendor. It's an auto-winder, and sports a titanium and steel case. The rubber strap adds the perfect "Marine" feel to the watch. And yes, it is water resistant to a depth of 100 meters.

"We were so pleased to be able to collaborate with Ulysse Nardin on our 40th-anniversary watch," says Jonathan Zadok. "Our desire was to create a piece that was sporty enough to wear with jeans, but could just as easily be worn with a suit. We think we've achieved that goal."

The Zadok 40th Anniversary special-edition timepiece by Ulysse Nardin is available exclusively at Zadok Jewelers.
