Labradorite Dial in the Signum Cero Watch
The dial is crafted from Labradorite, a feldspar mineral first discovered in Labrador, Canada.
- Base colors: deep blue or purple
- Flashes of gold, yellow, or violet appear at certain angles
- Each dial is completely unique
Collectors who enjoy stone dials may also find the stone dial collector’s guide useful. The Labradorite’s natural optical effect ensures no two watches look alike.
Bronze Case and Patina Development
The CuSn8 bronze case comes in 39.5mm and 42.5mm. Bronze reacts naturally with air and moisture, forming a patina that gives each watch a personal character. Learn more in my bronze watch care guide.
Patina development depends on wear and climate, giving every timepiece a unique story. Collectors often prefer leaving the patina untouched for its aesthetic value.

The Cero offers:
- NH35 automatic with lumed date disc

These movements are widely trusted in microbrand watches (Seiko Instruments). For more details, see the NH35 vs NH38 guide or the automatic watch movement overview.
