Former Chopard, Frederique Constant Executive Tapped to Head Cadar
Ralph Simons is now CEO of the jewelry brand started by fashion designer Michal Kadar and her husband, Avraham Kadar, in 2015.

He succeeds Jean Poh, who joined the company in February 2022 and left earlier this year.
According to his LinkedIn profile, Simons spent six years at Frederique Constant, working his way up to become president of the Americas market for the watch brand.
He served as CEO of Chopard North America for two years before moving on to Tane Mexico 1942, a Mexico City-based company that specializes in fine jewelry, collectibles, and objects.
Simons has spent the last eight-plus years as the CEO of Uptick New York LLC, his own strategy, consulting, and branding agency.
“Ralph’s impressive career demonstrates his ability to develop effective growth strategies that align with our aspirations for Cadar,” said Michal Kadar, the brand’s founder and creative director.
“I look forward to expanding our reach as we continue crafting distinctive, exquisite designs for our discerning clientele.”
Michal started Cadar in 2015 alongside her husband, Avraham Kadar.
Michal won Fashion Group International’s “Rising Star” award in the fine jewelry category in 2016—the year after she launched her brand—and took home a Couture Design Award in the “Best in Gold” category the following year.
Cadar is carried at Bergdorf Goodman, Saks Fifth Avenue, and Neiman Marcus as well as by independent jewelers including Marissa Collections, Broken English, Long’s Jewelers, and Reinhold Jewelers.
