The Miyota 8315: An Exceptional Powerhouse in the Realm of Automatic Movements

When it comes to the world of automatic movements, the Miyota 8315 really steals the show. This Japanese gem comes from Miyota, a division of the esteemed Citizen Company. What sets it apart? Well, it's got an impressive running time of up to 60 hours. That's right - this little powerhouse can keep ticking for two and a half days non-stop!​1​​2​.

Let's dive into some specs. The Miyota 8315 comes in at 11 1/2''' in size and 5.67mm in height. It rocks with a rhythm of 21,600 vibrations per hour and uses 21 jewels to keep everything moving smoothly. As for its precision, you can expect it to keep time within a range of -20 to +40 seconds per day​1​.

But it's not just about the specs, the 8315 is also a joy to use. With both automatic and hand winding capabilities, a quick date setting feature, and a stop second device, it's got all the functions you need wrapped up in one sleek package. Plus, it sports a date window at the 3H position, with a neat square shape, a crisp white background, and bold black letters. It's all in the details, right?​1​​2​.

One of the standout features of the Miyota 8315 is its compatibility. Based on the 8200 series framework, it plays well with most caliber 82XX dials, hands, and cases. This includes crowd favorites like the Miyota 8215​2​. It's basically an upgraded version of the 821A, complete with a shiny new mainspring and available in both silver and gilt versions. Talk about a glow-up!​2​.

The user-friendliness of the 8315 is also worth noting. It's got three crown positions for manual winding, date setting, and time setting. The best part? In the time setting mode, you can stop the seconds hand for precise time-setting. Now that's a feature you won't find in every movement out there!​2​.

The price tag for the Miyota 8315 won't break the bank either, with individual replacements ranging from $85 to $89.95 USD. That's quite a steal for such a high-quality movement​2​.
