GSI AW 91 733 Men Fashion Sports Watch Review

My watch was in the drawer for over a year and stopped working. I flashed my iphone torch directly on it for literally about 3 minutes and BRAVO it's working again.

This watch is described as "quartz chronograph", so it is not a self winding watch.

Go to http://www.tissot.ch/?mod_collections/action_getsubfamilies/colid_0002/famid_0012/refid_T044_417_27_031_00 for a description of the watch.

If it has stopped working, cold the battery be dead *have you had it for more than a year)?

Tissot is not one of the easiest site to interrogate!

If you go into the "collections" choose any watch to get all its details on screen, at the bottom of the information you will see a search box (why isn't it on the first page I hear you ask!).

Put PRS 516 into this and you will be presented with a row of watches (that row of dots can be used to move along the row).

When you find the one that looks like yours click on the picture and the details of the watch will appear and near the bottom will be "user manual" click on this.

Good luck.

Your Tissot watch is a chronograph. The large second hand is for the stop watch only. There is another second hand by the six that is for the time. To get the large second hand to move hit the top right button, that works the stop watch. If you already knew this and your large second hand is not going around then there is something wrong with the watch either a battery or needs service.

I would recommend going to the following link and follow the instructions for resetting the counters and see if that corrects the issue.
