NH35 vs Swiss Movements
The honest comparison: what a Swiss calibre buys you over a Seiko NH35, and where the difference genuinely does not show on the wrist.
Quick answer: The Seiko NH35 is cheaper, tougher and cheaper to service than Swiss automatics like the ETA 2824 or Sellita SW200, which beat faster (28,800 vph), are better finished and slightly more accurate. Seiko rates the NH35 at −20 to +40 seconds per day (Seiko's official spec).

The Seiko NH35 runs at 21,600 vibrations per hour with a 41-hour power reserve, 24 jewels, hacking seconds and hand-winding. A Swiss ETA 2824-2 or Sellita SW200-1 runs at 28,800 vph with a 38 to 41-hour reserve and 25 or 26 jewels.
The higher beat rate gives Swiss calibres a slightly smoother seconds sweep — eight ticks per second against six. It is visible if you look for it, and invisible if you do not.
Accuracy in Practice
Factory tolerance on the NH35 is -20 to +40 seconds per day, though most examples run far better than that in real use. A standard-grade Swiss 2824 is specified around ±12 seconds, and chronometer-grade versions to -4/+6.
The practical point is that regulation closes most of the gap. A regulated NH35 typically sits within about 10 seconds a day, which is well inside what most owners notice.
Finishing and Feel
Swiss movements are generally better finished — perlage, blued screws, decorated rotors — which matters on a display case back. The winding and hand-setting action also feels more refined. The NH35 is a plainly finished industrial movement designed for durability rather than display.
Servicing and Parts
- NH35: parts are cheap and universally available; a full replacement often costs less than a Swiss service
- Swiss calibres: servicing is more expensive and parts access is tighter, particularly for in-house movements
- Any competent watchmaker can work on either, but the NH35 is the lower-risk long-term ownership proposition
Cost — Where the Difference Really Sits
The movement cost difference is roughly £30 for an NH35 against £120 to £200 for a Swiss automatic. By the time that flows through case, assembly, distribution and brand margin, it is often a £400 to £800 difference at retail.
Which Should You Choose?
Choose Swiss if you want the smoother sweep, the finished movement behind a display back and the pedigree. Choose the NH35 if you want a robust, serviceable automatic and would rather see the budget spent on the case, crystal and bracelet. For a watch you wear daily rather than admire, the NH35 is the more rational purchase.

Frequently Asked Questions
Is the Seiko NH35 as good as a Swiss movement?
It is comparably reliable and far cheaper to service, but less refined. Swiss calibres such as the ETA 2824 beat at 28,800 vph against the NH35's 21,600, are better finished, and are specified to tighter accuracy — though regulation closes most of the accuracy gap.
How accurate is the NH35 compared with an ETA 2824?
The NH35 is rated -20 to +40 seconds per day and the standard ETA 2824-2 around ±12. In practice a regulated NH35 usually runs within about 10 seconds a day, which most owners find perfectly acceptable.
Why do microbrands use the NH35 instead of Swiss movements?
Cost and availability. An NH35 costs around £30 against £120 to £200 for a Swiss automatic, and supply is consistent. That lets a small brand spend more on the case, sapphire crystal and bracelet at the same retail price.
Is a Swiss movement worth paying extra for?
If you value the smoother seconds sweep, decorated finishing behind a display case back and Swiss provenance, yes. If you are buying a watch to wear hard every day, the NH35's low servicing cost and parts availability are the stronger argument.
