Vintage Timex Marmont NOS Quartz watch not running Dial England 58619 06679

Vintage Timex Marmont NOS Quartz watch not running Dial England 58619 06679. When I first got this watch I put a battery inside and the watch was running. It run for a few weeks and then stopped. Now if I put the battery back in it will run for a few seconds sometimes and then stop.

I couldn't get the little battery cover to turn so I had to open the back.
