The Rubber 1 is expected to feature a 1.85-inch OLED display, a 400mAh battery, USB-C and Qi wireless charging support and a 5 ATM waterproof rating. It will offer Bluetooth 5.3, Wi-Fi, NFC and health tracking for heart rate, blood oxygen and step count.

Interestingly, it could include a 2MP camera, something almost unheard of in smartwatches. As reported by Notebookcheck, the camera might be positioned above the display, similar to the JrTrack 4 Kids Smartwatch.

The Rubber 1S will come with a smaller 1.05-inch OLED display and a 290mAh battery. It has the same waterproof rating and health tracking features but ditches NFC in favor of Bluetooth 5.0 and Wi-Fi.

Both watches are expected to run Google’s Wear OS, possibly using a kid-friendly interface like the one seen in the Galaxy Watch for Kids, which launched earlier this year.

Given the basic health features and the presence of a camera, these smartwatches may be aimed at kids. HMD partnered with Xplora Technologies, a company known for children’s smartwatches, in October 2024. HMD could be looking to create a similar setup to the Galaxy Watch for Kids, which includes Family Link parental controls and teacher-approved apps.
