The movementMiyota 8215, in plain words
The movement, in plain words
Berny lists the Miyota 8215 for the AM138M-L.
How it runs. An automatic that also winds by hand through the crown. Wearing it keeps it running.
Beat. It beats 21,600 times an hour, 6 a second, so the seconds hand sweeps in small steps.
Off the wrist. It runs for about 42 hours once fully wound. Take it off on Friday evening and it will have stopped by Sunday around midday.
Setting the time. The seconds hand stops when you pull the crown out, so you can set it to the second.
Accuracy. Miyota's figure is -20 to +40 seconds a day.
On your wrist40 mm across, 12 mm thick, on a wrist your size
How it sits on your wrist
Set your wrist circumference to compare the 40 mm case with a schematic wrist. The ellipse estimates wrist width and shape. It cannot predict your fit.
17.0 cm6.7 in around
This wrist model is about 56 mm across. The case spans 71% of that estimated width. The lug span ends 4.3 mm inside each model edge.
Wrap a strip of paper round your wrist just below the bone, mark where it meets and measure it.
How tall it stands
The side view uses listed dimensions. Case shape and lug curve are schematic.

What owners report
Owner reports. Each covers one watch, so read them as things to check rather than a verdict.
From owners1 report
Owner describes a sterile C3-green mesh-bracelet example. They found the full-dial lume even and persistent and the mesh substantial for the price. That specific C3 variant is not proven identical to the current silver selector.
