ZURICH - Switzerland's Swatch Group plans to release a new long-life battery for smartwatches next year, the watchmaker's chief executive told a Swiss newspaper.
Swatch CEO Nick Hayek also told Swiss weekly Handelszeitung that the new battery would be applicable to cars.
"Whoever brings a battery for a smartwatch to the market that you don't need to charge for six months has a competitive advantage," Mr Hayek said in an interview, extracts of which were published on Wednesday.
"We're working intensively on this problem with our research group Belenos and battery producer Renata.
"Next year, we will come to the market with a revolutionary battery, not only for watches but also for automobiles."
A spokesman for Swatch confirmed Mr Hayek's comments.
In March, Swatch, the world's largest watchmaker, unveiled its riposte to Apple's smartwatch. The group outlined plans to put cheap programmable chips in watches that will let wearers make payments with a swipe of the wrist.
Reviewers of the Apple Watch were critical of the device's relatively poor battery life, which is up to 18 hours, according to Apple.
