This New York Jewellery Gallery Is Offering up a Treasure Trove of Vintage Watches
The Mahnaz Collection’s first formal collection of timepieces will include rare finds with fascinating histories

There was a period when Mahnaz Ispahani Bartos found it hard to hold on to a watch. The prominent collector and dealer often would post pictures on social media of the uncommon, sculptural timepieces she purchased for herself. But every time, clients of her eponymous jewellery gallery—New York City’s Mahnaz Collection—would hound her into selling them.
“They found those photographs, and they are just diligent in bothering me,” she says with a laugh, adding that some would simply persist until she changed her mind about letting them go.
In response to that demand, this month her Madison Avenue space will begin offering its first formal collection of unique watches, curated with the same rigor and studious eye Ispahani Bartos has applied to sourcing rare jewellery. (Her specialty is the hard-to-find fare made by artists, designers, goldsmiths, and architects.) One coveted example is a gold-and-diamond pendant watch handmade by the late Italian-born avant-garde designer Andrew Grima, whose work was beloved by the British royal family. This example from his historic collaboration with Omega was made in the 1970s. Lesser known but no less noteworthy is the Spanish designer Augustin Julia-Plana, who created a gold-and-jadeite watch for his brand Schlegel & Plana, also in the ’70s. “He was a great jeweller and watch designer,” says Ispahani Bartos of Julia-Plana, who penned striking and visually creative work for everyone from Chopard to Tiffany. “He specialised in really unusual stones,” she adds, noting that he died far too young at age 41.

Ispahani Bartos knows something about legacy. Born in Bangladesh—when it was still called East Pakistan—she grew up in a culture steeped in traditions of wearing and appreciating jewellery. She recalls her grandmother giving her earrings made from yellow gold, turquoise, diamonds, and Burmese rubies at age 7. (Too young to wear them, she put them on her dolls’ ears for safekeeping. Both were lost when her family fled the violence of the country’s 1971 revolution; the ship carrying their belongings, she says, was sunk by an enemy carrier.)
When she was a teenager, her mother gifted her one of Omega’s Grima-designed watches, which she still owns. That early introduction to rare design influenced her own collecting journey, which turned into her full-time job when she opened her gallery in 2013.

That comprehensive approach befits Ispahani Bartos’s previous career and intellectual curiosity. After earning a Ph.D. in international relations, she served as a foreign- and security-policy expert for an array of global organisations, including the Ford Foundation and the Council on Foreign Relations.
