How to Reset/Recalibrate A "Stuck" Quartz Chronograph

Ladies & Gents,

If you have a quartz chronograph and let's say it has a 30-minute subdial and for some reason the hand is stuck :-s at 29 when it should be at 30, most quartz chronographs have the same/a similar resetting method:

First, pull the crown out to the farthest position, typically where it lets you set the time. Then, hold down both chronograph buttons for a few seconds. Next, let go and if you push chronograph button one, it should advance the chronograph second hand once. Push that button until the chronograph second hand lines up at 12. If you hold down both chronograph buttons again for a few seconds, then push button one again, it should advance the chronograph minute hand once. This then lets you "unstuck" the chronograph hand from 29 to 30. Finally, simply push the crown back, and voila you're done.

This seems to be the standard approach for Swiss quartz chrono movements like ETAs. I have found that this works with my Wenger Aerograph Chrono, my former TAG s/el Chrono, and a search of the web shows that it seems to work for nearly all Swiss quartz chronos.

Enjoy! b-)

And now, a couple photos of my new baby!

I just used this to fix my 6 year old quartz Wenger. Thank you for posting this! I have been dealing with a chronograph for much too long that was not even close to zero set in any of its chrono hands. Just to touch on another variation of instructions for different movements, my Wenger required me to push only chrono button 2 to transition between chronograph hands instead of both chrono buttons.

Thanks for this, fixed my old Kenneth Cole (with Miyota movement).

I have a Tissot V8 Chrono quartz. My problem is the big seconds hand is not parked exactly at 12 when the Chrono is reset. I remember years ago my local watchmaker did a similar trick to realign the seconds hand when I had gone in for a battery change. Maybe I shud try this myself ... Any idea if it'll work on the V8?

I had to finally create an account to reply with gratitude for this post. I was searching all morning for a reset for my Tag Heuer CAH1011.BA0854 Formula 1 Grande Date. I sent it in to Tag Heuer for service and they changed the movement but the chrono hands on the 1/10th second and 30 minute markets were off. Tag does not list manuals online and this was the only solution that worked. I hope others in my situation will be able to search out this post to resolve their issues.

^^ bad luck : (

Just wanted to post that a similar method exists for a lot of seiko chronograph modules. The chrono hands on all the 7a's and 7ts iv handled can be calibrated by pulling the crown to the first outer position and then pushing the various pushers once to advance their specific hands.

Yet another example. The Alpina big date pilots watch and diver use the Ronda 5050.B movement with 1/10 timer and big date at the 6 position.

The adjustment process:

pull stem all the way out (after unlocking!)
hold both chrono pushers until big sweep second hand goes around once
now you can adjust the position of the sweep second hand with the number 1 pusher (at position 2 on the dial)
instead, hold the pushers down again
now you can adjust the 30 minute accumulator hand (subdial at the 9 position)
instead, hold the pushers down again
now you can adjust the 10 hour and tenths hand (subdial at the 3 position).

OP's hint was great and not too hard to discover the variations.

I thought that maybe the misalignment was a battery status indicator, but that is nearly always the 2 seconds jump. Glad it was so easy to fix.

I've got a chronograph with a Miyota 6S21 movement and just tried all this. It took me a looong time and a lot of fiddling, but I kind of have it figured out - or at least enough to fix my problem. In my case the chronograph minutes subdial didn't reset properly and was stuck at about 4 1/2 minutes.

Pulling the crown out to time setting and pressing the top (start/stop) chronograph pusher advances the chronograph seconds hand minutely, or alternatively you can hold it and after a second it will begin to scroll/spin to advance faster. BUT, pushing the bottom chronograph button, or holding it, does nothing - I've seen some advice online saying that the top pusher should advance the seconds hand and the bottom the minutes subdial, but that doesn't work for me.

I noticed that while resetting, when you advance the chronograph seconds the chronograph minutes also advances slightly, i.e. they're still mechanically linked as per normal and a full spin of chronograph seconds still advances chronograph minute subdial by a minute. So initially I just held down the seconds pusher for ages until the seconds hand had done ~57 sweeps and the minute hand had advanced almost a full sweep back to 12 o'clock again. But then after pushing the crown back in and testing it, the minute subdial just reset back to the same erroneous position.

So that left me with the problem of figuring out how to get the minute hand to move. I tried various combinations of holding both buttons (as advice above) and pushing things in different order, trying in the date setting position rather than time setting etc, but nothing seems to work.

I noticed when fiddling around that the minute hand seemed to be slightly earlier than before. At the start it was ~4 1/2 minutes but it seemed more like 3 1/2 at one point. I wondered if I was just imagining it, but it seemed like the minute hand had gone back slightly. Then I figured out that the manufacturer has built in this safeguard: since advancing the seconds hand also puts the minute hand forwards, once you've reset the seconds hand to zero, you can push the bottom chronograph pusher (reset pusher) and the minute hand will go backwards slightly.

So eventually to get the minute hand to go backwards far enough to get it back to 12 o'clock I did this (in time setting crown position):
  • hold the top pusher for long enough for the seconds hand to start spinning, then stop immediately.
  • press the bottom pusher, which would set the minutes hand back slightly
  • then repeat all of the above until the minute hand was at about zero.

At the end you need to do advance the seconds hand back to 12 o'clock and maybe do a bit of fiddling to get both hands lining up at zero.

After pushing the crown back in, screwing it down and testing the chronograph, it seems to be working as per normal with both hands resetting to 12 o'clock again. I still haven't figured out how to advance the minute hand by itself - perhaps the movement in my watch just malfunctioning.

Works even for my 10-12 year old Stauer Monaco Automatic! The watch that started my watch collection. Dr. Rod Donovan
