The Apple Watch 3 Cellular is available in two sizes — 38mm and 42mm. The 38mm Apple Watch 3 Cellular costs Rs 39,080 while the bigger 42mm version costs Rs 41,120. There’s also the Apple Watch Edition (GPS+Cellular) that starts at Rs 1,18,030 with ceramic case and sport band. For those unaware, Apple had launched the Watch 3 GPS in India last year itself at a starting price of Rs 29,900. Both the Apple Watch 3 GPS and Cellular offer the same specifications and features. The only difference is that the Watch 3 Cellular offers 4G LTE, UMTS via eSIM along with Wi-Fi (802.11b/g/n 2.4GHz) and Bluetooth 4.2 in the connectivity department. On the other hand, there is only Wi-Fi (802.11b/g/n 2.4GHz) and Bluetooth 4.2 connectivity in the more affordable Apple Watch 3 GPS.

There is no difference in the display quality of the Watch Series 3 Cellular and GPS versions. However, when compared to the Series 1 Apple Watch, there is a noticeable difference in brightness — 1000 nits in Watch 3 series compared to 450 nits in Series 1. However, the display resolution of 272x340 (38mm) and 312x390 pixels (42mm) remains the same.

There are three connectivity options in the new Apple Watch 3 Cellular -- Wi-Fi, Bluetooth and mobile connectivity. The Watch 3 automatically configures and decides to switch between Wi-Fi, Bluetooth and Cellular to provide the best experience. So, that you can always take or make calls, see messages and stay connected.

The network coverage of the iPhone and Watch 3 Cellular is not interdependent. This means that if your iPhone is at a location which has good reception and you walk with Apple Watch 3 Cellular into a place that has bad cell reception, then the Watch 3 Cellular will face difficulty in staying connected. Also, as the Watch 3 Cellular depends on eSIM connectivity provided by your cellular operator, the call drop situation will be similar to what you face with your iPhone in a particular location.

Like earlier, you can always connect to any Bluetooth earphone (or Apple AirPods) to make voice calls. Additionally, the speaker and mic on the Apple Watch 3 enables you to take calls without a Bluetooth earphone as well. Over the earphones, the call quality is equivalent to what you experience when your iPhone is paired to the Bluetooth headset. On speakers, it is difficult to have a conversation outdoors and in busy locations. But indoors the voice call quality is decent and you can easily manage to talk.

The Apple Watch 3 Series (both Cellular and GPS-only variants) is powered by a S3 dual-core processor along with W2 wireless chip. The hardware specifications have improved greatly when compared to the Series 1 Apple Watch to make the device more productive. You can expect a smooth performance overall and there is no lag or app freezes on the new Apple Watch 3 Cellular. This wearable does everything perfectly — be it voice calls, fitness tracking, Siri voice assistant, music and messages. The Cellular variant ensures that you can actually afford to forget your iPhone at home.

The Apple Watch 3 Cellular is claimed to provide up to 18 hours of battery life. Yes, you can get 18 hours battery life when you keep the Apple Watch 3 Cellular idle. But if you actively use the Apple Watch 3 Cellular, be prepared to charge it every night. Also, the battery life of the Apple Watch 3 Cellular depends greatly on the amount of voice calls you do. So, it’s always recommended to keep the charger handy.
