Plating loss is expected and is not a re-finish indicator
The gold-tone execution is plated, not solid, and wear through to the base metal on the high points is normal for the age. A gold-tone 6138-8020 with uniformly perfect plating has most likely been re-plated — which softens the case edges and is worth noting, but is a condition and originality matter rather than an authenticity one.
