A Swiss-made bronze diver with a natural pietersite stone dial—known for its swirling, storm-like chatoyance. The Pearl Diver “Pietersite” pairs a compact 40 mm case and 46 mm lug-to-lug with double-domed sapphire, 200 m water resistance, and the Swiss Sellita SW200-2 b automatic (no date). Raised 3D C3 X2 ef GL lume blocks keep the dial legible after dark.

Why it’s special
Pietersite stone dial
Pietersite’s layered fibers create dramatic movement under light. Expect natural variation—veining and color bands make each dial one-of-one.
Patina-friendly bronze
CuSn8 bronze mellows with wear, adding character. A Grade 2 titanium caseback keeps skin contact comfortable.
Swiss 3D lume blocks

FAQs
Is every pietersite dial unique?
Yes—patterning and color vary with each natural stone dial.
Can I swim or snorkel with it?
Yes—rated to 200 m. Always ensure the crown is fully screwed down before water exposure.
Which sapphire/insert should I choose?
Double-domed sapphire is a classic diver look; box-shaped top-hat adds vintage presence. Bronze inserts patinate; ceramic stays crisp.
