Miyota caliber 3S10 is a 12 jewels quartz chronograph/alarm movement, made in Japan. You may see this movement as 3S10 as well as 3510. If the movement is signed Citizen, it will be 3510. If it is signed Miyota it is 3S10. They are the same movement. Miyota is owned by Citizen Watch Co. Ltd.
Some of the topics covered in this caliber listing:
Accuracy:
Miyota states the accuracy of this movement to be +/-15 seconds/month in normal temperatures.
Coil Spring:
You may have noticed that the caliber 3510 has a marking below Citizen Watch Co. that says Coil Spring with an arrow pointing at a hole. This spring makes a connection from the piezoelectric device for the alarm to the caseback. Without the spring, you will not be able to hear the alarm sound.
Alarm not working after battery change?
If you alarm stopped working after a battery change, then it’s likely that the coil spring flew out when you opened the caseback. Most folks open watches with the 3510 totally unaware of the spring, then upon swapping batteries and putting the caseback on, find that the alarm is no longer working. This raises concerns because everything should work properly after a new battery cell.
If this happened to you, don’t beat yourself up over it, not many movements have a tiny spring that just sits in a hole without anything holding it in place.
Here are some solutions if you lost your coil spring (if any of these worked for you, please comment below):
- Try to find a replacement coil spring on eBay.
- Look for an inexpensive quartz/alarm movement or parts watch with a similar spring. Casio and other brands also use coil springs for the alarm contact.
- If you just replaced the battery, you could try to use a magnet sweeper to sweep your floor.
- You could attempt to take a springbar apart and use one of the springs until you get a replacement. Springbar springs are about the same size in diameter, so it should fit, but will most likely need to be cut in half.
Pros and Cons of the caliber 3510:
Pros:
- Alarm feature
- Cool factor that a Miyota is found in genuine Breitling (and other Swiss) watches
Cons:
- The coil spring is easy to lose
