The Seiko NH70A is one of the most important movements in the affordable luxury watch market. Used by independent watch brands globally — and by Verso Parnell across their entire automatic skeleton range — it represents the right answer to a specific question: what automatic movement can deliver genuine reliability, visible skeleton aesthetics, and long-term serviceability at a price that doesn't inflate the watch beyond its market position?

Why 24 Jewels?
Jewels in a watch movement are synthetic ruby bearings that reduce friction at key pivot points. 24 jewels in the NH70A is a generous count — covering all the critical gear train, escapement, and rotor pivots. More jewels mean less metal-on-metal friction at every rotation, which translates directly to longer service intervals and more consistent accuracy.
The 41-Hour Power Reserve
41 hours means you can take the watch off Friday evening and put it back on Sunday morning and it'll still be running. For a daily-worn watch, this is comfortable — you won't be winding it manually every day. If you leave it for two days, winding through movement for the first 20–30 minutes of wear will rebuild the mainspring charge.
What Hacking Seconds Means
When you pull the crown to set the time, the seconds hand stops instantly. This allows you to synchronise the watch precisely — something not available on older or lower-spec automatic movements. It's a small feature that matters to buyers who take accuracy seriously.
Why It's Inside Every Verso Parnell Skeleton Watch
Verso Parnell chose the NH70A for three specific reasons:
- Skeleton compatibility: The NH70A is designed to be displayed — its architecture works visually when the dial is skeletonised, with clear rotor action and visible gear train.
- Proven reliability: The NH series has accumulated millions of hours of field use across thousands of watch models globally. Failure rates are exceptionally low.
- Long-term serviceability: The NH70A can be serviced in any competent watch workshop anywhere in the world. In the UAE, any qualified watchmaker can work on it.
NH70A vs ETA 2824 vs Miyota 9015
| Movement | Power Reserve | Jewels | Accuracy | Price Segment |
|---|---|---|---|---|
| Seiko NH70A | 41h | 24 | ±45s/day | Entry luxury |
| ETA 2824-2 | 38h | 25 | ±12s/day | Mid luxury |
| Miyota 9015 | 42h | 24 | ±10s/day | Entry-mid luxury |
The NH70A is slightly below the ETA 2824 and Miyota 9015 in rated accuracy, but in day-to-day use the difference is negligible for most wearers — a few seconds per day is invisible unless you're time-synchronising multiple times per week.
Verdict
The Seiko NH70A is the right movement for what Verso Parnell is doing: visible skeleton mechanics at an accessible UAE price point, with reliability that will outlast most buyers' interest in upgrading. It's not an ETA 2892 or a Rolex in-house movement — but at AED 2,100–2,500, it doesn't need to be.
