"We decided to market the Gear S3 midway through November at the latest in Korea and some other countries," a Samsung official said. "In China, the timepiece will be launched later."
The price of the two models ― the Gear S3 Frontier and the Gear S3 Classic ― would be different but they are likely to be in the neighborhood of 400,000 won ($356).
Samsung unveiled the Gear S3 in late-August at the IFA trade show in Berlin, Germany.
The water-resistant gadget, with a 3.3-centimeter circular display, has an in-built global positioning system (GPS) and the capacity to make contact-less payments.
In an emergency, Gear 3 users can tap the back buttons three times to send SOS signals and their location to designated friends or relatives, even if the smartwatch is not connected to a cell phone.
Users also can access thousands of applications, while the watch has a maximum four-day battery life and plenty of health-tracking functions.
The G3's competitor is the Apple Watch Series 2, introduced last month with the iPhone 7.
