I have got Tissot PR50 having a barcode 5054000418 since last 5 years and no problem till now but since few months it is not working properly and stops frequently about 4 to 5 times in a day. I visited to Limton Watch Co. in Karachi to check my watch, They go through with it and told me it is having some prob. in there small gears, thats some of them broken from the middle so its stops several times in a day. I am not at all statisfied with answer and i want a proper justification for this issue. Please consider my complaint on priority. Even i have one PR 50 Automatic thats working great and looks nice on my hand.
