The ceramic colors of the gen and rep are actually different as well, with the gen color being a deeper black.I like the ceramic... I really would have bought it but I've seen chipped bracelets and the broken bracelet issue doesn't inspire huge confidence in me. Maybe in 6 months I'll get one
Also the tactile feel of both gen and rep are very different, with the rep being a lot rougher especially around the edges.
Seen and felt alone, these are not issues but next to the gen, the differences are very obvious.
