Display, Form Factor, and Hardware Design
The physical footprint of a wrist wearable fundamentally influences daily comfort and style. The Charge 5 adopts an elongated band design built with a stainless steel case and a stainless steel band secured by a deployant folding clasp. Its color touchscreen is engineered to be twice as bright as the Charge 4 in direct daylight. Weighing very little and hugging the wrist closely, it fits wrists from 5.1 inches up to 8.3 inches using the small and large bands provided in the package. Its narrow, modern profile stays discreet under tight clothing or dress cuffs, making it comfortable to wear 24/7.
The vívoactive 6 takes the shape of a traditional sports watch, centered around a 42mm round AMOLED touchscreen display. The case is constructed from lightweight fiber-reinforced polymer, paired with a comfortable silicone band and a standard tang buckle.
