I have a Casio Divers Digital watch,model DEP-610C(almost a G-Shock!!!!!),its virtually new but as i have not worn it for a while,i asked Casio UK how much they'd charge for a battery change/reseal they qouted Me. . . . .£160 inc.VAT(Our form of sales tax)!Now bearing in mind that they only charged £25 for My G-Shock Frogman which is also a Divers watch!Any ideas of getting a cheaper battery replacement done?Thankyou in advance! .
