APPLE 49mm Navy Ocean Band Natural Titanium Finish | ref ECI-MXTJ3ZM/A

Made from the same high-performance elastomer as the Ocean Band, this strap extension lengthens the 49mm Ocean Band by an additional 50 millimetres — perfect if you need extra length to wear the strap 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 strap into. This extension must be used with the standard Ocean Band.
