Apple MXTL3AM/A 49mm Black Ocean Watch Band

The Apple Watch Ocean Band in black with a natural titanium finish is purpose-built for people who take their Apple Watch into demanding aquatic environments. The band is constructed from a high-performance elastomer with a distinctive tubular geometry that allows it to stretch for a snug, secure fit — whether worn directly on the wrist or over a wetsuit during diving, surfing, or other water sports. Unlike standard silicone bands that rely on a pin-and-tuck closure, the Ocean Band uses a titanium buckle paired with an adjustable loop, creating a fastening system engineered to withstand the forces of high-speed water activities without coming undone.

Compatibility spans Apple Watch models with 44mm, 45mm, 46mm, and 49mm cases, covering the full range of larger Apple Watch sizes including the Apple Watch Ultra. The band accommodates wrist circumferences from 130mm to 200mm out of the box, with an optional extension band available separately for use over thicker wetsuits. Despite being designed for extreme conditions, the Ocean Band remains comfortable enough for everyday wear — the elastomer is soft against the skin, dries quickly, and resists degradation from repeated saltwater and chlorine exposure. For Apple Watch owners who spend serious time in or around water, this band replaces the anxiety of a loose strap with genuine peace of mind.
