In July, No.1 released a statement that the company is working on an upgraded version of its flagship smartwatch, the D5. The upgraded version of the smartwatch is simply dubbed as No.1 D5+. No.1 has now released the smartwatch on pre-sale for a limited time.

The D5+ is said to similar to the original model. This could mean that No.1 would make most of the upgrades under the hood. The D5+ retains the circular design of its predecessor with a 1.3-inch display sporting a 360 x 360 resolution.

Standard functions like the heart rate monitor, calorie counter, and pedometer are included on the new D5+. Aside from these basic features, the smartwatch also supports Wi-Fi, GPS, and Bluetooth. No.1 also includes a feature that is fairly uncommon to smartwatches, a SIM card slot, and 3G network support.

Perhaps the biggest upgrade of the D5+ is its chipset. According to Giz China, the No.1 D5+ now sports a MediaTek MT6580 chipset, with 1GB of memory and 8GB of storage space. The MT6580 is a decent chipset that requires less power to operate. This means that the 450mAh battery pack of the D5+ should be able to power the smartwatch for an extended period. The No.1 D5+ runs on the Android 5.1 Lollipop.

The No.1 D5+ is currently available for pre-sale until Sept. 20. The smartwatch has been priced $109.99 for the duration of the pre-sale, although the price might jump once it is finally launched.
