Can you recommend a watch battery replacement tool?

I have an upcoming event that is perfect for this Seiko pilot’s watch that I bought years ago just because it had so much stuff on it. (Hey, I’m easily amused.)

The watch has sat for so long that the battery died.

I see so many options for watch battery tools on Amazon–blue ones, yellow ones, silver ones. Are they all the same? Is the one from Acfun better than the Jorest? 

Thanks.

I do know HF has had an adjustable one for a while.  In case you want to see it in person:

I prefer the 3 pin tool, more grip to prevent slips.

Harbor Freight sells one too, and a 2 pin tool with a kit.

TIL that Harbor Freight sells watch tools. Thanks! Of course, this means that I have to leave the house....

I've been told that the seal is a one time use so you might want to avoid taking the watch into the water if you don't replace it.

I got mine from Amazon.  It came in a little yellow box that says "GDGJ No. 2098A Case Opener for waterproof watches.  I've used it a couple of times and it works much better than a pair of needlenose pliers that invariably slip and scratch the literal bejeebus out of the back of your watch.  It was part of a larger kit.  Recommended.  Best of all, I didn't have to leave the house.

Good that you have a screw on back.  If it were a snap one, just take it to the battery replacement store.  I broke a watch trying to snap one back together.

Same.  Fortunately, it was not an expensive watch.  And it belonged to my wife.    I can buy her another one.

I've had to resort to carefully squeezing the case with pliers to get some of the harder-to-snap-together cases shut.  Not fun.

I just wait until I have two or three dead watches and then take them to Batteries+.

This is the one I bought, it worked well.

I've been watching some watch repair videos recently, it seems the repair guys often use a small children's rubber ball to remove the watch back - they just press it against the back and turn it.  If you google 'rubber ball watch back removal' a bunch of short videos demonstrating the technique pop up.

You're going to miss this opportunity to start ogling the tools and other bits and bobs at Esslinger (no relation to the 4-cyl Ford folks, AFAIK) or Cas-Ker?

Try a racquetball or a hockey puck.

I like the racketball idea, but I need to see if I have the tool for that. 

Worst case, I’ll wear it with a dead battery. Not the first time I have worn a watch that wasn’t displaying the correct time. 

Thanks. 

I'm sorry; I cannot help myself.

"Does anybody really know what time it is? Does anybody really care?"

I deeply apologize, and will see myself out.

Let me see... looks like it about 25 or 26 to four...

According to my watch, it’s like three to three.

That's "two fifty seven", if you're under 35. 
 

At least, according to my kids...

I got this kit off the 'zon about a year ago to change the battery my Nautica "daily" which looks pretty similar to your Seiko.  I remember it being about $16.00.  Not exactly jeweler quality but I've opened my watch, my son's cheapo and my wife's Movado to swap out batteries without any issue.  I haven't tried the band pin tool but it looks like it would work on my watch.

This got bumped by spammers, but an update: Still haven’t replaced the battery. 

I just use my Leatherman's plier tips and twist.

The two jaw adjustable opener from Harbor Fright will work fine. The o-ring seal is good IF you have a silicone grease lubricant before you put case back on, preferably the silicone grease case that is sold for watches. More than happy to help if you want. I have a ton of watch tools, almost as many as car working tools. I do custom watch stuff all the time.
