Modern Casio watch, brass

Purchased new in 2018, worn occasionally since then. From their vintage collection. Model # A159WGE. No big scratches or damage, but does show evidence of wear with micro marks on the metal, see photos. Still running on original battery / back casing has not been opened. Easy to adjust for wrist size. Features alarm, timer, and backlighting. I love this watch. Other people tell me how much they love this watch. Selling due to a metal allergy :(
