Yeah the rep is a good watch for the price! It wears well on the wrist, is stealthy and is not cumbersome like the 46mm models.
The functions do work, but where the gen operates via the crown (like the Breitling Aerospace), the rep has sunken pushers which you need a biro to push. So, they are not normally useable "on the run".
I've not seen the rep with the std dial, only with the FAF logo. Nor have I seen the silver case version.....by the way, the rep lume is "ok" for rep lume, but is green. The hands aren't lumed for some weird reason!
