Braille is quite small though? Perhaps it's just a stylistic choice, or the mechanism/durability constraints demand a larger size.
- readme 11y agoMany blind people tell the time by feeling the machinery on their watches. This is simply a watch which is designed for that and I would imagine, less prone to the issues usually experienced: e.g. a blind person might have a watch with the face removed, and touch the hands in order to tell the time. The problem is the hands can move slightly, so it throws off the watch's accuracy.
- jonesetc 11y agoThat's right. The magnets that keep the balls in place are on the inside. You can move the balls and they will just roll back into place[0], eliminating the chance of setting the time. [0] https://www.youtube.com/watch?v=ZiNHDF2e54s https://www.youtube.com/watch?v=ZiNHDF2e54s
- Someone 11y agoWatches for the blind are called Braille watches but (almost?) never use Braille to indicate time digitally (http://en.m.wikipedia.org/wiki/Braille_watch http://en.m.wikipedia.org/wiki/Braille_watch) A normal analog watch with a sturdier mechanism and stronger hands, that can be flipped open to feel the location of the hands is cheaper and smaller than anything with refreshable Braille cells.
