A heavy handed approach to branding.
Over design - design for the sake of it.
Claiming a movement is "in house" when it has been outsourced and simply refinished.
Illegible face - ie a watch where it becomes difficult to actually read the time.
Asymmetric faces – for example a sub second dial placed at 5 O’clock.
Partially occluded numerals on a dial.
Bejeweled cases.
