The Miyota caliber 2453 is a quartz movement with 0 jewels. It is considered a replaceable movement.

Similar Calibers:

Miyota caliber  2415 and 2405 are similar to the 2453, with the main difference being that the 2415 has a normal size date window at 3:00, and the 2405 has a day/date at 3:00. The 2453 has a wide date.

Wide Date:

Watches with the caliber 2453 will feature a wider-than-usual date window at 3:00 with a wide font. Although this appears to be unique design by the brands using this movement, it’s actually already designed like this from Miyota.

Calendar Variations:

The Miyota 2453 is available in two configurations. They are identical with exception to the color of the date wheel and text.

  • 2453-20A – White background with black text
  • 2453-20X – Black background with whit text

The minimum wholesale order when buying from Miyota is said to be 1,000 pieces per each style. What’s interesting is that the white model appears to be readily available, but the black background date wheel model has a lead time of about 2 months. This makes sense as we rarely see 2453 powered watches with a black date wheel.


Miyota states the accuracy of this 2453 movement to be +/-20 seconds/month.

Power Reserve:

The 2453 has a battery life of 3 years. This movement also has a hacking function which can serve as a power saving feature. Pulling out the crown/stem to time setting position can reduce the power being used if you’re not going to wear the watch for a while. Be careful storing your watch with the stem pulled out!

Crown/Stem Removal:

Miyota calibers such as the 2453 do not have an arrow to indicate the location of the release button for stem removal. There are several peg-like shapes sticking out of the movement that appear to be buttons, but they are actually there to hold parts of the movement in place. Instead, you will be looking for a small indentation, which you will press down with your tweezers to allow for the stem to be released.

The crown should be pressed in to 0 position, but thanks to the fool-proof design, when you pull the crown out, the indentation is hidden to prevent releasing the crown in the incorrect position. Follow the video below:
