THE KW88 PRO
Largely thanks to its IP67 certified aluminum casing the KW88 Pro feels like a much more expensive smart watch.
It's 1.39 inch AMOLED screen may not be as large as the 1.53 inch IPS screen used in the THOR PRO model by Zeblaze (placed on the right for comparison purposes) but it's certainly a lot more common in smart watches.
Due to its smaller screen the KW88 Pro is generally a smaller smart watch (46mm in diameter and 13.5mm in thickness) compared to the THOR PRO (48.7mm in diameter and 15.3mm in thickness).
The dial around the screen is less "populated" compared to that of the THOR PRO (you may like that more, or not).
A small speaker is located on the left side of the casing while on the right side we find a aluminum button right next to a 2.0 Megapixel camera and a microphone.
Unlike the silicone strap/band used with the THOR PRO the one used with the KW88 Pro is perforated so wrist temperatures should be reduced.
At the rear of the watch we find the heart rate sensor, 4 gold plated contact pins (used to recharge the interior battery) and a small compartment.
Inside this small compartment is the nano SIM card slot which you can use if you want the KW88 Pro to also act as a standalone smartphone.
