Miyota caliber 0S10 is a quartz chronograph watch movement with zero jewels. Miyota is owned by Citizen and this movement is made in Japan. The caliber number is often written incorrectly as OS1O or 0510. The Citizen branded version of this movement is 0510.

High Hand Versions

The caliber 0S10 has two high hand versions: 0S1A and 0S1F.

Calendar Locations

The base 0S10 movement has the date window at 3:00. This movement is also available with the date at 4:00, between 4:00 and 5:00, as well as at 6:00. Black and white background date wheel versions are available.

Accuracy Rating

Miyota states the accuracy of the caliber 0s10 quartz movement to be +/-20 seconds/month.

Chronograph

The 0S10 chronograph seconds has a quick reset to zero. Miyota calls this the Heart Cam Reset System.

How to Reset to Zero?

If your 0S10 chronograph hands need calibrated back to zero after a battery change, follow the steps below:

  1. Pull the crown to position III (time setting position)
  2. Press pusher A (the top button) to advance the chronograph hand forward. Long pressing will advance the hand rapidly.
  3. When the hand is at zero or 12:00, push the crown back in.

Replacement Price

Replacement prices for the Miyota caliber 0S10 movement were found in the range of $25.00 – $31.95 USD.

Examples of watches with this movement

The image below is of a Miyota 0S10 found in a Locman Italy Sport chronograph watch. There was no plastic movement holder and the pushers reached from the case to the movement.

Here is another example of a caliber 0S10 found in a Skagen watch. Also no movement holder needed and the case was designed so that the pushers can reach the movement buttons to operate the chronograph stopwatch feature.

Seems there is no way to ‘reset’ the chronograph minute ‘sub hand’ or the ‘Hour Sub hand’ (to zero). the only thing that can be RESET is the sweep second hand. this seems strange?? anyone have other info on this?

that is correct. the ONLY hand that can be ‘reset’ to ‘ZERO’ (12 o’clock position) is the Sweep second hand (pull crown out to 2nd position and using button A move hand in clockwise motion until it’s pointing at 12 o’clock). however the ‘SUB DIAL hands” (for chrono minutes and Chrono Hours) cannot be moved and are NOT pointing at the 12 o’clock position. how is this accomplished? the Miyota manual does not provide this… Read more »

Sometimes you can try in different crown positions. So pull it out one click to the date setting position (position 1) and try the top and bottom buttons. If that doesn’t work, try it again in time setting mode (position 2). These directions are more geared towards Ronda movements, but might be worth checking out: https://www.keepthetime.com/blog/how-to-set-an-invicta-chronograph-back-to-zero/

Yes, that is the same conclusion I found. only the sweep second had can be reset (strange). I wonder in the factory how it’s done? that’s what I was looking for the ‘factory’ short cut. maybe shorting some pads on the back of the movement? Not sure. thanks

Instructions from Casio for this caliber (they call it Module 2328) do specify how to reset the hour and minutes on the chronograph.

It is used in the AMW330 and MSY-501 models, amog others. Unfortunately mine seems to be damaged (which is how I found this forum) and I cannot test this.

I found a way to do this without dismantling! At the 2nd crown position, press and hold button A to speed up the Chronograph seconds. Continue holding and the Chronograph minutes will advance…. slowly but surely. Once it reaches 12 (slowly press A for accuracy), press button B to fix the minute hand position, then push the crown back. Try this when the minute hand advances 5minutes first before commuting to hold long hold. Hope… Read more »

Anybody know if there is an automatic movement this size that would take the same hands from the Miyota Caliber No. OS10? I’m curious if I can do a movement swap in a Jack Mason chronograph I have. Does Miyota make an automatic chrono movement? I ask this before I’ve done much digging, so my next step is to start looking for movements with the same dimensions. I’m only looking at Miyota movements because I’m… Read more »

Gentlemen, the question arose how to ‘reset’ the chronograph minute ‘sub hand’. OK it´s a while since but the info may be of future interest. I posted an inquiry directly to Miyota how to accomplish this but did not get any answer yet. Obviously there is no feature to ‘electrically’ reset the minute sub hand. Here is the solution that worked for me: Dismantle the movement from the watch case, then GENTLY push the minute… Read more »

I figured out how to calibrate the minute hand. It is not so simple as just pressing the ‘B’ button in time-setting mode. You have to press ‘A’ so that the stopwatch seconds hand advances, and then that allows you to press ‘B’ to advance the minute hand. The B button cannot be pressed without pressing A first. So once you calibrate the minute hand you can adjust the seconds back to 0. If only… Read more »

Ok never mind, that was just a fluke. After fiddling with the buttons the stopwatch minute hand fell off.

Did you get it out? Be careful prying, I did that once and it chipped the edge of the paint on the dial. Luckily it was covered by an internal bezel, but still I wasn’t pleased about it at all. Try to flip the case over on your hand and try to see if the movement falls into your hand. That’s how I usually do it. It needs to be exactly a round circle for… Read more »

These are a the workhorse movement for Miyota. You’ll find them in thousands of watches, from $10 fashion watches to $200+ “sub-lux” monsters. Reliable under normal circumstances, but highly susceptible to becoming magnetized, slowing them to a crawl. Losing five minutes a day on one with a brand new battery… even though the other seven in my stable with the same movement have been within one minute for months. Nothing to write home about, pretty… Read more »

If new battery doesn’t fix it then it probably needs oiled or something junked up the gearing. Does it slow down at a certain time each day and are you running the chronograph? Check the connections too and make sure the battery connection does’t have junk on it.
