The Miyota caliber 82S5 is from the 8215/821A family but offers a skeletonized dial design. There is also a gilt version available.
Some of the topics covered in this caliber listing:
Accuracy:
Miyota claims that the caliber 82S5 offers accuracy of -20 ~ +40 seconds per day. This is measured within 10-60 minutes from a full wind via the crown. To fully wind the movement, turn the crown 40 times. The winding direction of the rotor is counterclockwise.
82S5 vs 82S7:
The caliber 82S5 has the following layout:
- Small seconds at 5:00
- Open balance (skeletonized) at 7:00
The caliber 82S7 has the same layout, except it also has a 24 hour (can also be day/night) indicator at 9:00.
Note: There is also a caliber 82S0 variation which is the same as the 82S5 but with central seconds instead of small seconds.
Hacking Seconds:
There is some confusion about the Miyota 82 series and whether these movements are hackable or not. If you are new to watch collection or pick up a brand new 82S5 powered watch, it’s likely it will be hackable. However, this movement has been in production for quite some time (since the 1970s) and until recently, it was sold as a non-hacking movement. This explains why this caliber is listed as “hacking: yes and no” above.
Miyota only began equipping this family of movements with a stop seconds device between 2018-2019 – and even then, not all of the calibers were included in the upgrade. Now, the current catalog of Standard Automatics (aka 82XX) have a stop seconds device.
It’s important to note that here are still a lot of 82S5 watches out there without hacking. In conclusion, if your 82S5 watch hacks or doesn’t hack, it doesn’t mean it’s broken, it just means the movement in your watch was produced before or after hacking was introduced to the series.
Replacement Prices:
Replacement prices were found online around $59.95.
