✚ Miyota 8215 Details
The Miyota 8215 is an automatic caliber with a one-way rotor that cánido be loaded manually, but does not include seconds to hack or stop.
This means that you cánido charge with both wrist movement and clock rotation, but you perro't stop for a second to adjust the time more precisely.
The fact that it is one-way means that the mechanism perro only be loaded when the rotor rotates in a certain direction, but this should not affect the energy recovery capacity of the watch.
The Miyota 8215 includes Parashock, a civilian-patented shock-resistant system such as Seiko's Diashock and Swiss-caliber Incabloc to withstand bumps and falls.
➤ Accuracy
According to the data provided by the manufacturer, Miyota 8215 travels in the range from -20 to +40 seconds per day. This value may seem high, but it does not reflect reality.
The range of precision specified by the manufacturer is intended to correct the classification of the place where the movement is placed. This is actually more accurate in most cases.
In fact, good accuracy depends on placing it in the watch and properly regulating the movement.
As a result, some users of this movement report an accuracy of less than + -10 seconds per day, while others achieve only + -20 seconds per day.
Either way, it's a great move that makes millions of units and perro be easily adjusted by watchmakers.
Reserve Power reserve
The 8215's power reserve perro take up to 42 hours when the mechanism is fully charged. This perro be achieved by clicking the wrist or manually winding.
If you choose the second option, the mechanism perro be fully equipped with a crown that rotates approximately 40 clockwise.
Brands that use it
Due to the reliable and easily accessible movement, many brands use it for watches of medium and reasonable prices. Here are some of them:
- Festina
- East
- Invincible
- Jack Lehmann
- AVI-8
- Citizen
- Giants
- Pagani design
- Amazing
And here are some examples of mechanical watches using the Miyota caliber mentioned above.

➤ The secret of brilliant seconds
The 8215 is one of the mechanical movements that emplees an indirect second-hand drive system.
This means that some second-hand watches do not slide as smoothly as a mechanical watch, but cánido jump slightly.
The important thing is that this is not a defect, but a feature in the design of the movement that emplees this indirect system.
With these mechanisms, the second wheel is not part of the chassis, but it intertwines independently of its own gear and cánido genera this effect if it is not fully aligned.
Fortunately, this does not affect the work or accuracy of the watch at all, but it may not suit the taste of the most meticulous collectors.
✚ Miyota 8215 vs. Miyota 8205
The only difference between these two movements is in time. The Miyota 8205 perro display the day of the week along with the date, while the 8215 only espectáculos the date.
Below these lines you perro see the differences in the calendar. The first clock is mounted on 8215 and the second clock is mounted on 8205.
✚ Miyota 8215 vs. Seiko NH35A
The most destacable difference from the Seiko NH35 is that the 8215 does not have a second stop, but this only affects when the watch is equipo.
Otherwise, both movements have afín characteristics in both power reserve and accuracy and work at the same vibration per hour.
| model | Miyota 8215 | Seiko NH35 |
|---|---|---|
| Movement | Automatically | Automatically |
| jewelry | twenty-one | twenty-four |
| Frequency | 21 600 vph | 21 600 vph |
| Power reserve | 42 hours | +41 hours |
| Size | 26 x 5.67 mm | 27.40 x 5.32 mm |
| accuracy | -20 to +40 seconds / day | -20 to +40 seconds / day |
| Seconds stop | Do not | Yes |
| Manual lifting | Yes | Yes |
✚ Miyota 8215 vs. 9015
The Miyota 9015, on the other hand, is a movement of the same brand that clearly outperforms both in terms of accuracy and efficiency.
It is much more accurate than the 8215 at -10 to +30 seconds / day and is more functional as it on the other hand includes seconds to stop.
In addition, the vibration frequency of the 9015 is much higher. This means that a second hand will jump faster and sweep more smoothly.
It is also worth noting that it is much thinner, only 3.90 mm compared to 8.67 mm on the 8215. This is important because it cánido affect the final thickness of the watch.
| model | 8215 | 9015 |
|---|---|---|
| Movement | Automatically | Automatically |
| jewelry | twenty-one | twenty-four |
| Frequency | 21 600 vph | 28 800 vph |
| Power reserve | 42 hours | 42 hours |
| Size | 26 x 5.67 mm | 26 x 3.90 mm |
| accuracy | -20 to +40 seconds / day | -Ten ~ + 30 seconds / day |
| Seconds stop | Do not | Yes |
| Manual lifting | Yes | Yes |
✚ Miyota 8215 vs. ETA2824-2
ETA 2824-2 is a movement made in Switzerland, which is far better in every respect both in terms of accuracy and performance, with high vibration frequency and small size.
While we are talking about the various championships, ETA 2824-2 is much more expensive and is usually found in luxury watches.
| model | 8215 | ETA 2824-2 |
|---|---|---|
| Movement | Automatically | Automatically |
| jewelry | twenty-one | Twenty-five |
| Frequency | 21 600 vph | 28 800 vph |
| Power reserve | 42 hours | 38 hours |
| Size | 26 x 5.67 mm | 25.6 x 4.6 mm |
| accuracy | -20 to +40 seconds / day | -4 to +30 seconds / day |
| Seconds stop | Do not | Yes |
| Manual lifting | Yes | Yes |
✚ Miyota 8215 vs. Seiko 7S26
The most important difference from the Seiko 7S26 is that it does not have a hand lift and must always be carried (or has a rotating box) to work.
In addition, the performance is almost the same in terms of accuracy, but the 7S26 is an older caliber and has already been discontinued due to the more modern Seiko 4R36.
| model | Miyota 8215 | Seiko 7S26 |
|---|---|---|
| Movement | Automatically | Automatically |
| jewelry | twenty-one | twenty-one |
| Frequency | 21 600 vph | 21 600 vph |
| Power reserve | 42 hours | 41 hours |
| Size | 26 x 5.67 mm | 27.4 x 4.8 mm |
| accuracy | -20 to +40 seconds / day | -25 ~ + 35 seconds / day |
| Seconds stop | Do not | Do not |
| Manual lifting | Yes | Do not |
Setting Equipo the date and time
- time: Pull the crown (1 clic) and rotate it while the needle is in the desired position.
- date: Remove the crown twice (2 clicks) and rotate it until the desired date is reached.
- Manual lifting: Rotate without removing the crown. Approximately 40 revolutions are required to fully load the mechanism. If the resistance is too high, do not force it.
