Here we have some prototypes of the rubber strap and the Sapphire bezel for the upcoming 300M. We should have our case and bracelet prototypes ready in a few weeks (or less). Initial thoughts: I am not happy with the bezel lume application on the sapphire so we will most likely print the background and apply the lume by hand for max impact and neatness. The rubber strap is awesome. I like this one quite a bit! Its a bit thicker than our other rubber straps but still nice and soft. We did the same underside as our other rubber strap to help keep moisture at bay under the strap.
