This month, Swatch said it developed the world's smallest Bluetooth chip for use in watches and household objects.
Swatch's approach will work better because it's trying to "think small" as one of the biggest problem for wearable devices is battery drainage, Hayek said, speaking at the Biel, Switzerland headquarters of Omega, another of 18 brands that Swatch produces.
"There's a possibility for wearables to develop as a consumer product, but you have to miniaturise and have an independent operating system," the chief executive said.
"I'm not convinced," said Luca Solca, an analyst at Exane BNP Paribas who follows the luxury industry. "People use smartwatches expecting to use the same apps they have on their mobiles. A proprietary operating system defeats the object."
Swatch is willing to supply third parties with the operating system, which has been developed with the Swiss Centre for Electronics and Microtechnology, a university specialising in miniaturisation, Hayek said. The company has received about 100 requests for more information, with half coming from smaller Silicon Valley companies that don't want to be dependent on Android and iOS, he added.
Separately, Tissot has yet to start selling its Smart Touch smartwatch, according to Francois Thiebaud, head of that brand. He said last year the solar-powered watch would be available during 2016, and that it would be connectable to Android and Apple smartphones. It also would have functions such as showing the weather.
