Where to buy a strap

look on ebay , that is your best bet

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)?

I have examined their web site and found the nearest model to yours.

If you go to "http://support.tissot.ch/?mod_flashPDF/id_144/familyName_PRS%20516%20Chrono/search_T91142", you should arrive at a page which has a download in the top right.

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.

hi its a bit of a grey area as some cheap watches boast 50m water resistant but as its a tissot you should be fine but id rather you went to tissots website to make sure, just as long as you dont go diving it should be fine, good luck

Go to www.tissot.ch

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.
