Miyota 82S0 — Purpose-Built for Skeleton Dials
The Miyota 82S0 is specifically engineered for open-heart and skeleton watch designs — parts of the dial-side bridge are removed, allowing a view of the balance wheel and other moving components directly from the front of the watch. This is the key distinction from the 8215 and 8205, which are conventional automatics with fully covered dial-side bridges. The 82S0’s open architecture means the movement IS the dial display — the oscillating balance wheel, gears and bridges are the primary visual content.
As of mid-2019, Miyota integrated a hacking mechanism into the 82S0 — the seconds hand stops when the crown is pulled out for time-setting. Confirm from the production date whether the specific AM198M unit includes hacking.
Full confirmed specifications: 21 jewels, 21,600 vph, approximately 42 hours power reserve, automatic and hand-winding, stop second device, 5.67mm height.
3D Open-Heart Dial Architecture
The AM198M’s “3D” designation refers to the multi-layer physical relief of the open dial — not a printed effect. The balance wheel oscillates in real time through the front aperture; the layered bridges and plates create depth and shadow at different angles. The outer dial elements (raised markers, large minute numerals) frame the open movement view.
The combination of the Miyota 82S0’s exposed balance wheel viewed from the front and the sapphire exhibition caseback presenting the rotor from the rear creates a watch that shows the movement from both sides simultaneously.
Nylon vs Leather — AM198MNY and AM198M
The AM198MNY suffix indicates a multi-colour nylon strap — high-density woven fabric with a centre stripe pattern. The nylon creates a sport-casual character appropriate for the bold mechanical dial aesthetics. The AM198M uses a textured leather strap with stitched edges — a more formal presentation of the same case.
Sapphire Both Sides
Sapphire front and sapphire exhibition caseback. Both surfaces are Mohs 9 scratch-resistant. The caseback presents the Miyota 82S0 rotor in motion. Combined with the open-heart front dial, the AM198M has visible mechanical motion from both front and back.
BERNY AM198M vs LOBINNI 16067 NH39 Skeleton
Both are skeleton automatics at 42–43mm in the range:
| Feature | AM198M (this page) | LOBINNI 16067 NH39 |
|---|---|---|
| Movement | Miyota 82S0 (skeleton-specific) | Seiko NH39 (no-date skeleton) |
| Skeleton type | Open-heart — partial front view | Partial open-work + honeycomb |
| Colour accents | Orange, mint green, gold | Red, blue, green, yellow |
| Case | 42mm / 12.5mm | 43mm / 10mm |
| Strap | Nylon or leather | Leather only |
Choose AM198M for the Miyota 82S0 open-heart balance wheel view, nylon strap options and mint green / orange accent dial colours. Choose LOBINNI 16067 for the NH39 Seiko movement, thinner 10mm profile and the partial honeycomb dial architecture.
Who Is the BERNY AM198M For?
The AM198M is built for:
- Open-heart skeleton buyers who want the balance wheel visible through the front dial on a Miyota-specific skeleton caliber
- Mint green or orange dial buyers — AM198M-MGN and AM198M-ORG are uncommon colour options in the automatic skeleton category
- Nylon strap skeleton buyers who want the casual fabric strap on an open-heart automatic
- Sapphire-both-sides skeleton buyers who want maximum scratch protection on both viewing surfaces
How It Compares
vs. LOBINNI 16067 NH39 — See comparison table above.
vs. Bonest Gatti BG9960 Gravity — BG9960 uses RTC-13 at 45mm yellow acrylic with full skeleton. BERNY uses Miyota 82S0 at 42mm steel with open-heart. Full skeleton vs open-heart — different degrees of movement exposure.
vs. BERNY AM093M Skeleton — The sibling BERNY skeleton at 40mm. Compare case size and dial architecture between the two before selecting.
