I would love to have an e-Strap that coordinates with my $1000 mechanical Robert Weil watch.
If the e-strap came from Montblanc, Google, Apple, or pebble I would not mind. As long as it matched and gave me usable functionality. Also, when I sent it in to Robert Weil for service, they respected the e-Strap, even if it was from Montblanc.
