We were super stoked when Reserve Strap announced its power giving Apple Watch band – but it appears the project is now dead in the water.
It seems Apple has scuppered the project with a recent update to watchOS, which prevents accessories from communicating with watch via the diagnostic port, hidden under the strap clip. That spells the end of Reserve Strap, which promised to extend battery life by 150% – equating to a week of use at a time.

"Beginning with WatchOS 2.0.1 an unexpected change to the Apple External Accessory Protocol disabled the functionality of Reserve Strap," the Reserve Strap makers wrote on their web site.
While the problem is described as a bug by the Reserve Strap team, they also stated that "Apple has suspended use of this port until they unveil an official MFi program for Watch." That essentially means that Apple has pulled the plug on the party until it can create a standard for the smart strap category and/or release its own.
Shipments of Reserve Strap have been suspended, although anyone who's not going to update their Apple Watch can still receive a strap.
