Automatic or quartz? It is one of the first decisions any watch buyer faces, and the answer depends entirely on what you value. Neither is objectively "better" β they serve different purposes and appeal to different tastes. Here is what you need to know.
How Quartz Watches Work
A quartz watch uses a battery to send an electrical current through a tiny quartz crystal. The crystal vibrates at a precise frequency (32,768 Hz), and a circuit counts those vibrations to keep time. The result is exceptional accuracy β typically within Β±15 seconds per month.
Quartz movements are the backbone of the Paul Rich Frosted Star Dust and Signature collections. They are reliable, accurate, and require minimal maintenance beyond an occasional battery change every 2β3 years.
How Automatic Watches Work
An automatic (self-winding) watch is powered by a mainspring that is wound by the natural motion of your wrist. A weighted rotor spins as you move, transferring energy through a series of gears to the mainspring. No battery needed β just regular wear.
The Paul Rich Astro collection uses high-quality automatic movements, including the NH70 movement in our skeleton models. These movements are visible through the open dial, turning the engineering into a visual feature.
Head-to-Head Comparison
| Feature | Quartz | Automatic |
|---|---|---|
| Accuracy | Β±15 sec/month | Β±20β30 sec/day |
| Power source | Battery (2β3 years) | Wrist movement |
| Maintenance | Battery changes | Service every 5β10 years |
| Thickness | Typically thinner | Often thicker |
| Second hand | Ticks once per second | Sweeps smoothly |
| Price | Generally lower | Generally higher |
When to Choose Quartz
- You want a grab-and-go watch that is always accurate
- You rotate between multiple watches and do not want to reset them
- You prefer a slimmer profile on the wrist
- You want the best value at a given price point
When to Choose Automatic
- You appreciate mechanical engineering and craftsmanship
- You enjoy the ritual of wearing a watch daily to keep it running
- You want a sweeping seconds hand (that smooth, flowing motion)
- You like the idea of a watch that does not need batteries
Paul Rich Offers Both
We design watches in both categories because both have their place:
- Quartz: Frosted Star Dust, Star Dust, Signature, Frosted Signature
- Automatic: Astro (Day & Date, Classic, Skeleton), Motorsport
Some models β like the Moissanite Frosted Star Dust II β are available in both quartz and automatic variants, so you can choose the movement that fits your lifestyle.
