Eta Caliber G10 211

The ETA caliber G10.211 is a Swiss “assembled” quartz chronograph movement with 4 jewels. This movement is part of ETA’s Fashionline group of quartz movements. This caliber is not considered to be a repairable movement and is largely found in entry level lower priced timepieces.

How to Change the Battery:

The G10.211 takes battery number 394.

Replacing the battery on your G10.211 watch is very straightforward. The diagram below is from the official ETA tech sheets. As pictured, place your tool between the battery and the arm that holds it in place (#2 in the image below). Gently pry the arm back and the battery should lift up. Be careful not to bend of break off the arm that holds the battery in place!

Eta G10 71a Battery ChangeTo install the new battery, do the process in reverse, but make sure the battery is placed under the lip first (#3 in the image above).

Pro Tip: If you install a new battery and the watch doesn’t function properly, it’s possible that the battery is bad. Always try a new battery before giving up.

Recalibrate the Chronograph Hand to Zero:

After installing a fresh battery, you may need to reset the chronograph hands on your watch. This is because when the battery runs out of energy while the chronograph is running, the last location of the chronograph hand will become the new “zero” until you reset it.

Resetting the hands to zero is easy and you don’t need to send your watch back to the company or a watchmaker.

  • Pull the crown to position 2 (date setting)
  • Press the bottom pusher to adjust the central chronograph second hand
  • Press the top pusher to adjust the 1/10 second hand
  • Pull the crown out to position 3 (time setting)
  • Press the top pusher to adjust the 30 minute hand
  • Press the crown in to position 1 (against the case) when finished

*Some manufacturer’s refer to the crown position numbers differently. We always try to refer to the positions the same as the manufacturers do. ETA crown positions are as follows:

Eta Caliber G10 71a Crown Positions

Crown/Stem Removal:

To remove the crown, look for the stem release hole on the movement near the crown There is a small arrow pointing to it…

Eta Caliber G10 71a Stem Removal

Putting the crown to date setting position should reveal a button in the hole that you can gently press with your tool to release the stem. Do this carefully and do not press too hard. If you damage the stem release mechanism, there doesn’t seem to be a way to fix it since it’s encased in plastic.

For visual learners, here is a video.

Replaceable, Not Repairable:

This movement is part of ETA’s Fashionline group of quartz movements. This caliber is not considered to be a repairable movement and is largely found in entry level lower priced timepieces.

With that said, some folks find ways to repair them, depending on what’s wrong with it. This video is a good example.

In ETA’s Own Words:

“Movements of these calibres can-not be disassembled; therefore, this document contains informa-tion on electrical tests and hand-fitting only.” -ETA

Discontinued:

The ETA caliber G10.211 has been discontinued.  Caliber G10.212 is a possible replacement.

Replacement Price:

At the time of this post, replacement prices for the G10.211 were not found online because it has been discontinued. Prices for the replacement caliber G10.212 were found in the range of $45 – $59.99 USD.

Metal Plate/Cover:

The metal plate on the G10 family of movements is just a thin cover with sticky adhesive. Below this metal cover you will find an plastic encasing that holds everything together.

This is what the movement looks like below the metal cover:

More Macro shots:

Eta G10 211

Pros:

  • Relatively inexpensive chronograph functionality with “Swiss” labeling.
  • Easy to recalibrate if the chronograph second hand isn’t lining up.
  • Does not need an insulator tab under the battery.
  • It has been around for a while with proven reliability overall.

Cons:

  • Not serviceable, other than changing the battery.
  • Easy to damage the stem removal mechanism, making it difficult to remove from the case.
  • Made outside of Switzerland even though some brands will lead consumers to think it is a Swiss ETA G10.
  • Poor documentation by the manufacturer.
  • Discontinued by the manufacturer.

Utilized in the Victorinox Chrono Classic. Mine is almost supernaturally accurate. It hasn’t gained or lost even a tenth of a second in three months. That’s well within quartz chronometer certification standards. Not too shabby for a conventional quartz movement!

Mine has almost not perceptibly gained anything over the last 30 days. That is calculated by eyeballing the second hand compared to the atomic clock in Boulder Colorado. This is as good as any COSC movement, except the citizen that costs north of $7,000.

Don’t let the ETA stamp fool you. This G10 quartz movement is total unserviceable welded shut piece of junk. You’re better off with a Ronda or even a Miyota or Seiko quartz before buying any watch with a G10 shitter.

Yes. The movement is low end, plastic and there are no plans to possibly repair it. But watch out! ETA is a very serious manufacturer. Msm this movement in its very cheap Swiss Military Hanowa s watches has been completely accurate for over 14 years. 100% reliability for more than 14 years. Thank you.

Do you have one? Mine is in my Tissot PRC 200. Flawless performance so far. Accuracy is off the charts good. How often does anyone ever service their quartz watches. I have an Omega constellation quartz from around 1990. Took it in for service after about 10 years and they simply swapped out the movement. Good for me as the replaced movement keeps better time than the original one did. Still, it is 10 seconds a month fast. My G10.211 gains next to nothing per month. So which one is better?

It may be a welded-shut piece of junk, but I’ve had mine in a Victorinox Summit Chrono (it was used when I bought it) since 2004. It’s never lost more than 1 second a month, often going several months perfect accuracy: +/- 0.0 seconds. I use the USNO Naval Observatory time as my standard.

Never had a problem. The other brands you mention are well regarded, though.

I have a bag of these from replacing customers movements. One day they’re working fine, and then the next the time keeping part is dead, or the entire thing is dead. Sad, because at a retail level, these aren’t cheap to replace. I’d recommend paying very close attention to how battery changes are conducted. Properly reseal and pressure test too. Once these are compromised, they’re trash. Same can be said for any watch. Just because it’s running, doesn’t mean you shouldn’t have some preventative maintenance done. Could save you a $200 repair. But, even then, I’ve seen these die with… Read more »

Each battery change should be accompanied by a gasket change for the case back and crown. There is a lubrication that is applied to these gaskets (very light) that helps preserve the rubber gasket and help with the seal. I wonder when people say how bad these movements are. Mine function perfectly, line up properly, and keep unbelievable time. Even my Tissot Seastar chrono (1,000 feet) keeps time to 3 or so seconds fast per month. The aesthetics of a quartz movement is absolutely irrelevant. That it is not serviceable is also irrelevant. I have seen, however, where such a… Read more »

I have this movement in my Tissot PRS 200. I checked its accuracy against the atomic clock. Over the last 20 days it has not visibly gained or lost anything. Look, ETA has figured out how to make quartz movements that are this good. Modern manufacturing techniques are such that they can produce something like this very cheaply. That does not mean in any way that it is a cheap movement in terms of quality. What I ask of my movements is precision and durability. This movement does this in spades. Additionally, the indices line up perfects with the hands.… Read more »

Check with a local watchmaker if you have one close and ask for an estimate to fix. There may be a simple connection issue or ask how much to replace this quartz movement. This movement is still available at watch supply stores at approximately $60 and could be sourced by you or the watchmaker, depending on which would be cheapest. The watchmaker would then simply switch out the movement. Cheaper than buying an entire new watch.

I have replaced three of these g10 movements in the space of a year on the same watch, when the owner runs the chrono function because he likes the second hand to move it uses a battery in a month.
one of the biggest pieces of rubbish I have ever worked on.
He payed $800 secondhand the movement is $70 and its a stainless steel case yep great value for your money. i will use my money on far better quility watchers for this price

A “decent” watch is any watch that appeals to someone and is reasonably accurate (i.e. almost any functioning quartz watch) For example I have an inexpensive Timex digital watch that I bought in the mid 1980’s. It still functions perfectly in every way 40 years later. I call that a decent watch.

I will have to disagree. Invicta, and others, are cheap watches. That a cheap watch lasts a long time is no indication of its quality. The fit, finish, movement quality, etc., all are more important. Their quality does not even come close to Certina, Tissot, or Longines.

It’s all BS really. I can show you higher end Invicta watches that are better quality fit and finish than lower end Tissot, Certina, and Longines. And quality is subjective, since one collector cares about finish and another cares about durability. Another funny BS is that most of the people commenting about watches online haven’t actually handled enough watches to justify their judgements. It’s a lot of people repeating what they heard others say (and repeating marketing points successfully injected into the market’s mind) without experience to back it up. And even if you have that experience to back it… Read more »

And if I’m lucky enough to get my grail watch, hands down it will be a Grand Seiko….

Tissot PRC 200

Original piece as told by a certified Tissot watchmaker. Make sure your piece is an original, before criticizing the movement inside it.

* 14 years of daily use, with chronometer use of 20min/day.
* It keeps perfect time (or close to that), so I only adjust it after battery replacement.
* Renata battery lasts 22 months.
* Bumped it against hard surfaces a couple of times, still, no issues whatsoever.

Great page, by the way, it brings me understanding and peace of mind.

I recently had the movement of a Tissot J378/478 replaced in a shop. A few weeks later, the hour hand got stuck in place, then it unstuck itself in a wrong position after I wiggled the crown in hour-setting position. I opened the watch, removed the crown to get access to the dial and was able to reposition the hour hand correctly. Seems to be working fine now.
