It varies greatly, none of my quartz watch has a battery that lasts as long as specified by the manufacturer.

 

Seems like my battery quartz watches last 2-3 years. Chronographs on the shorter end of the spectrum, especially if the chrono function is used a lot.

 

The original battery is often a bit short of puff and I think it’s Casio that actually say that you may not get the full expected life out of the OEM battery.

 

Around 2 yrs for the Duro, but it only has a low mAh 626 batt. It was one of the things i didn't like about it.
Edifice mostly use a bigger 927 batt, i used to get around 3.5 to 4 yrs from them.
I mostly have solar these days, but have a couple of G Shocks that use CR2025 and CR2032 batts. I expect to get around 10 years from these. Same with a Casio AE-2000 i have.
Really, i'm only interested in solar and autos now.

 

Cell size is a factor. A few analog quartz watches that use a large lithium cell can run up to 10 years.

 

How often you use any backlight or chronograph will obviously have an impact on batt life.
I remember i had a ana/digi G Shock, a G-100, that i wore to work for 11 years. It only took 2 small button cells, but it was still on its original batts when i retired it after 11 years. Only the backlight was getting dim.

 

Well beyond five years for mine.

 

Besides the movement, the hand size also plays a role i think, if the hands are smaller/lighter, it will also use less energy to keep it going.
I've got a small 7N43 powered Seiko, that needs a battery about every 6-7 years on average.
The hour hand on it is about as big as the second hand in my tuna, so that puts it a bit in perspective for size.

 

Mine all, every single one of them, last until they die. When that ultimately occurs I change the battery and have absolutely no idea when the last time was that I had to.

 

So far, 2 1/2 years on the OEM battery with my Duro. Still running strong, though it sounds like I'd better get a replacement on hand.

 

Three years on the Duro. That was three years ago so I expect it to need another one soon.

 

I had an Omega Seamaster Quartz from 12-18-2000 till 2-12-2011. The battery was changed twice, 6-23-05 and 8-18-2010. I was very happy with that.

My and my wife's quartz Luminoxes have required battery changes every 2 years or so.

this matches my experience exactly with the same watch. Purchased in 2003, battery has been changed every 5 years and a few months, still wearing it today.

 

Real-life case study.

My Victorinox watch has the Ronda 715 movement with manufacturer-rated battery life of 60 months (F.I.V.E years).

Strange enough, whatever battery brand I used, be it Sony, Panasonic, Varta... Even with a excellent expiration date, the EOL indicator on the watch always kicks on at the third year, sometime sooner.
