Apple 49mm Midnight Ocean Band Extension

Made from the same high-performance elastomer as the Ocean Band, this band extension lengthens the 49mm Ocean Band by an additional 50 millimeters — perfect if you need extra length to wear the band over your wetsuit.
The extension comes with an extra adjustable, corrosion-resistant titanium loop which you can place in any tube to tuck the excess band into. This extension must be used with the regular Ocean Band.
