The watch will be available as of October, it said at an event in Berlin tied to the IFA, Europe’s largest consumer electronics trade show.
Making the new smartwatches compatible with smartphones made by competitors could help sales for Samsung, which saw its market share shrink sharply following the launch of arch rival Apple’s Apple Watch.
Worldwide smartwatch shipments grew to 5 million in the second quarter of this year from 1 million in the same period last year, according to data of research firm Strategy Analytics.
“We are leading the way in this segment,” said Younghee Lee, Samsung’s global marketing head for mobile. “But we realise we can’t do it alone.”
Apple Watch captured a 75 percent global smartwatch market share, followed by Samsung with an 8 percent share.
Samsung launched its new watch on Monday. The Gear S2 comes with mobile payment technology just like Apple’s Watch.
Samsung did not give a price tag for the watch.
