The NH35 and Miyota 8215 occupy similar territory: both are date-equipped automatic movements used in accessible mechanical watches. Neither choice automatically makes a complete watch better. Case construction, regulation, dial and hand fitting, water resistance, and quality control still matter.
The most useful comparison starts with what the manufacturers publish and then looks at the movements inside the same watch. DailyTime Store's CORGEUT 6033 offers both NH35 and 8215 variants with the same 40mm case, sapphire crystal, 100M rating, dial colors, and bracelet format. That removes many of the distractions found when two unrelated watches are compared.
The short answer: the NH35 offers 24 jewels and a slightly slimmer published movement height, while the current 8215 specification offers 21 jewels, stop-seconds, hand winding, and a lower price in the CORGEUT 6033. Your best choice depends on which differences you value and how much of the budget you want to put into the movement option.
NH35 vs Miyota 8215 specifications
The NH35 figures below come from Time Module Inc.'s NH35 product page. The 8215 figures come from Miyota's official 8215 page. These are movement specifications, not promises about the performance of every finished watch.
| Specification | TMI NH35 | Miyota 8215 |
|---|---|---|
| Display | Three hands and date | Three hands and date |
| Frequency | 21,600 vibrations per hour (3Hz) | 21,600 vibrations per hour |
| Stop-second device | Yes | Yes |
| Jewels | 24 | 21 |
| Published movement height | 5.32mm | 5.67mm |
| Published origin | Japan or Malaysia | Made in Japan |
| Additional maker-listed details | Full reference list and technical documents are available from TMI | Automatic and hand winding, quick date setting, approximately 42-hour running time, and -20 to +40 seconds/day |
TMI's public product summary does not display an accuracy tolerance or running time beside the NH35. Rather than fill those cells from memory, this comparison leaves them out and links to the manufacturer's technical documents. Specifications can also vary by reference and production configuration, so confirm the exact movement documentation when sourcing for a commercial project.
What the shared specifications mean on the wrist
Both use the same published frequency
Both manufacturers list 21,600 vibrations per hour. That means the basic beat rate does not give either movement an automatic advantage in seconds-hand motion. The finished impression also depends on the hand, dial markers, movement condition, and how closely you look.
Both current specifications include stop-seconds
A stop-second device halts the seconds hand when the crown is pulled to the time-setting position. This makes it easier to synchronize the watch to a reference time. TMI lists the feature for the NH35, and Miyota's current official page lists it for the 8215 as well.
This is worth checking against current documentation because older discussions of the 8215 may describe earlier specifications. For a buying decision today, the manufacturer's current page is the better reference.
Jewel count is not a simple quality score
The NH35 has 24 jewels and the 8215 has 21. Jewels are low-friction bearing points used at selected locations in a mechanical movement. A higher number can reflect a different design, but three additional jewels do not prove that the complete watch will be more accurate, more durable, or better assembled.
Compare jewel count as one design fact, not as a ranking system. Regulation, lubrication, shock history, magnetism, and service condition can have a much more immediate effect on a watch you actually wear.
The movement-height difference may not change the watch case
TMI lists the NH35 at 5.32mm high, while Miyota lists the 8215 at 5.67mm. That difference can matter when a watch is being engineered around a movement. It does not necessarily make one finished watch visibly thinner than another.
In the CORGEUT 6033, both movements are options within the same 40mm watch model. Choose based on the complete watch specification and fit, not the movement height alone.
A direct price comparison in the CORGEUT 6033
As checked on August 21, 2026, all six movement-and-dial variants of the CORGEUT 6033 Automatic Watch were available for sale. The NH35 option was US$102.90 and the 8215 option was US$76.90 in Ice Blue, Black, and Silver. That is a US$26 difference within this model.
The shared product specification lists a 40mm stainless steel case, stainless steel bracelet, sapphire crystal, luminous hands or markers, date display, and 100M water resistance. Those are properties of the finished watch, not of the movement. Selecting the NH35 instead of the 8215 does not itself change the crystal or water-resistance rating.
Prices and availability can change. Check the product page before ordering rather than treating the figures in this article as a standing quotation.
Which movement should you choose?
Choose the NH35 option when:
- you specifically want the TMI NH35 architecture;
- the 24-jewel specification matters to your brief;
- the slightly lower published movement height is relevant to a future design discussion; or
- you are comfortable paying the current premium in the 6033.
Choose the Miyota 8215 option when:
- the lower current price in the 6033 is a priority;
- you want Miyota's published automatic and hand-winding specification;
- the maker-listed approximately 42-hour running time suits your needs; or
- you prefer the movement's made-in-Japan specification.
For an everyday buyer, there is no need to turn the decision into a contest between logos on the rotor. Decide whether the movement preference is worth US$26 in this particular watch, then evaluate the case size, dial, bracelet, crystal, and complete price.
What microbrand and small-batch buyers should check
A movement decision for a branded project has more consequences than a single retail purchase. The movement affects the case and dial engineering, hand specifications, date position, stem and crown arrangement, sourcing, servicing plan, and target price. A prototype should confirm the entire assembled watch rather than the movement name alone.
DailyTime Store supports base-watch logo customization and small-batch projects, subject to model and process availability. It does not follow that every retail model or movement can be turned into a full private-label production program. Share the intended quantity, budget, logo positions, and schedule through the custom service brief before treating a retail option as a production platform.
For a one-piece branded sample, the custom logo watch service can be used to submit authorized artwork and confirm whether the selected base watch is eligible.
Frequently asked questions
Is the NH35 better than the Miyota 8215?
Not in every watch or for every buyer. The NH35 has 24 jewels and a lower published movement height. The current 8215 specification lists 21 jewels, automatic and hand winding, stop-seconds, and approximately 42 hours of running time. The quality of the finished watch and its regulation still matter.
Does the Miyota 8215 stop the seconds hand?
Yes. Miyota's current official 8215 page lists a stop-second device. Older online discussions may refer to earlier versions or older published specifications.
Which movement has the smoother seconds hand?
Both makers publish a frequency of 21,600 vibrations per hour, so beat rate alone does not separate them here.
Which option is cheaper?
In the CORGEUT 6033 on August 21, 2026, the 8215 variant was US$76.90 and the NH35 variant was US$102.90. That comparison applies to this product at that time, not to every watch using either movement.

The practical verdict
The NH35 and Miyota 8215 share the core features most buyers need: three hands, a date display, an automatic format, a 21,600-vibration-per-hour frequency, and stop-seconds in their current published specifications. The NH35 brings 24 jewels and a slimmer listed movement height. The 8215 costs less in the CORGEUT 6033 and comes with a clear maker-published running-time specification.
Choose the movement after choosing the watch, not instead of choosing the watch. The case, crystal, fit, water resistance, assembly, and current price are the parts you will live with as a complete product.
