Quick take:
- Sizes: 40 mm and 44 mm cases (Graphite or Silver)

Bands & Fit: What You Should Know
Watch8 introduces a Dynamic Lug System for a snugger fit and better sensor contact. You can choose from first-party band families—Sport, Fabric, Athleisure, and Hybrid—in multiple colors and sizes (S/M and M/L). For the best comfort and readings, wear it snug (not tight) and keep a small gap above the wrist bone.
How to Clean the Watch Band (Fast & Safe)
Regular cleaning keeps the band comfortable and your skin happy—especially after workouts.
- After sweating, wipe the band with a soft, lint-free cloth and dry thoroughly.
- Avoid chemicals like sunscreen, insect repellent, detergents, antibacterial sprays, or hand sanitizers.
- For stuck-on grime, use a slightly moistened soft-bristle toothbrush, then dry completely.
- Leather bands: wipe gently with a dry or lightly damp cloth, then air-dry away from direct heat/sunlight.
Tip: If you have sensitive skin, keep the area dry and clean, and give your wrist occasional breathers.
