Quartz Tier: Precision Chronograph
#8: Miyota 6S21 – Analog Chronograph
The Miyota 6S21 powers affordable analog chronograph watches, delivering stopwatch functionality without the complexity and cost of mechanical chronograph movements.
Specifications:
- Type: Quartz chronograph
- Subdials: 3 (hours, minutes, seconds)
- Height: 5.55mm
- Battery Life: Approximately 3 years
- Accuracy: ±20 seconds per month
- Movement Cost: $15-25
Why it ranks #8: The 6S21 serves a specific purpose: enabling affordable chronograph watches. Mechanical chronographs require complex movements costing hundreds of dollars; the 6S21 delivers similar functionality for a fraction. For Daytona-style aesthetics without mechanical complexity, quartz chronographs like the 6S21 make practical sense.
Alternative consideration: For chronograph styling, some watch builders choose the Seiko VK63/VK64 meca-quartz movements instead. These combine quartz precision with mechanical-feel chronograph pushers, creating a hybrid experience. Companies like SKYRIM WRIST use VK63 in their Daytona-inspired collection ($315), prioritizing the satisfying tactile feedback of meca-quartz over pure quartz operation.
Best for: Affordable chronograph watches, Daytona-style designs on limited budgets, buyers who prioritize function over mechanical purity.

Frequently Asked Questions
Which Miyota movement is best?
The Miyota 9015 is objectively Miyota's best movement, offering 28,800 vph frequency, hacking, hand-winding, and slim 3.90mm profile. It matches or exceeds many Swiss movements in specifications while costing $45-70 at movement level. For buyers prioritizing features and quality within the Miyota family, the 9015 is the clear choice.
Is Miyota 9015 worth the upgrade over 8215?
Yes, significantly. The 9015 adds hacking (seconds hand stops for precise time setting), hand-winding (restart without shaking), higher frequency (smoother sweep, better accuracy), and slimmer profile (enables elegant case designs). The $25-45 cost difference at movement level translates to meaningful daily-use improvements.
Which Miyota movements have hacking?
Only the 9-series movements include hacking: 9015, 9039, and 90S5. All 8-series movements (8215, 821A, 82S7, 8N24) lack hacking, meaning the seconds hand continues running when setting time. This is the primary reason enthusiasts prefer 9-series or alternatives like the Seiko NH35.
Are Miyota movements reliable?
Yes. Miyota operates under Citizen, bringing decades of Japanese manufacturing expertise. Both budget 8-series and premium 9-series movements run reliably for years with standard maintenance. The difference lies in features and finishing, not fundamental reliability. Service intervals of 5-7 years are typical for properly maintained Miyota automatics.
Miyota or Seiko: which movement is better?
It depends on the comparison. The Miyota 9015 offers advantages over Seiko NH35 (higher frequency, slimmer profile), but costs more. The Seiko NH35 matches 9015 features (hacking, hand-winding) at near-8215 pricing, making it better value for most applications. For slim dress watches, 9015 wins; for overall value, NH35 often makes more sense.
Conclusion: Know What You're Getting
Miyota's movement lineup spans from flagship 9015 to workhorse 8215, with meaningful differences at each tier. Understanding these differences prevents disappointment:
- 9-series (9015, 9039, 90S5): Complete features, premium performance, justifiable for $300+ watches
