I would go with your TD's advice and buy the SS version . It has nice polished centre links anyway . I avoid gold plated watches because they rub and become tarnished . Also hair spray , perfume body lotions etc are the worst culprits for tarnishing , so if a women's is wearing watch
I'm sure people will tell you if the gold plate is thick enough you will have no problem . However from personal experience they all tarnish eventually.
