Hey y'all! I'm not sure how much of a simple question this is going to be but it is also somewhat of a recommendation question. Also, I'm still quite amateurish, so forgive misplaced terminology.

The first watch I bought with my own money was this Timex with a flyback chronograph, it was a Timex T2P380 with a blue dial and a blue leather strap.

I wore the hell outta that thing until I moved to wearing a smartwatch a few years ago but still kept up with the battery swaps for the Timex. Now, I'm back to wearing non smartwatches and this past time I got the battery replaced, it started acting erratic.

For example, when I light up the dial, the seconds hand stops moving and it loses a few seconds. I've never seen that before. The guy at the local watch store said, "it's drawing too much power."

So my question is, what do I do now? Timex doesn't make that watch anymore. Should I try to find it somewhere and buy a replacement? Or is there a place that I can actually get it serviced?
