HI,most watches when buy new n after wearing for 2or 3 yrs the value will drop from 20% to 50% n some even to 70% depending on brand. For some models after about eight yrs. , it will start appreciating to the value when you bought it new. these testament of time models, they don't change much in design even from maybe 40 yrs. ago,of course the technology has improved tremendously like the materials , hairspring, balance wheel, water proofing , anti magnetic , lubricant for different parts. but not everyone will accept these watches , they will want modern design watches. Before you buy a watch maybe ask yourself, ten years down , could i still love this watch or if the design could survive the testament of time??
