First-Party Options: Active Sport (silicone), Woven (textile), Metal Link (stainless steel), Leather bands.

Size Considerations by Use Case

Fitness: 41mm won't interfere with most activities, lightweight for running and gym workouts.
Professional: Appears understated and professional, fits under dress shirt cuffs (mostly).
Sleep Tracking: 36g is light enough for comfortable overnight wear, though 12.3mm thickness may feel bulky initially.
Small Wrists: Excellent choice - perfectly proportioned without overwhelming the wrist.
Large Wrists: May appear compact - try before buying if wrist exceeds 190mm.

Measure circumference in millimeters
