Founders Edition · Limited First Series
An understated 39mm mechanical dress watch featuring a dial cut from natural honed Jerusalem limestone. Every dial carries a grain formed over millions of years—no two watches are alike.
Sunlit Jerusalem limestone arches at golden hour—the inspiration behind every Sionne dial.
The Material
For centuries, the architecture of Jerusalem has been defined by its local pale-cream limestone—a stone that shifts from soft ivory in the morning to warm gold at dusk.
Rather than painting or stamping a metal dial, we slice thin veneers of natural pale-beige limestone and hone the surface to a soft, non-glossy matte finish. Framed by a slender polished bezel and minimalist baton markers, the stone remains the sole centerpiece.
Proportions
Inspired by mid-century dress watches, the 39mm case is sculpted with brushed flanks and a slender mirror-polished bezel that slips effortlessly beneath a shirt cuff.
Paired with a supple espresso-brown Italian calfskin strap and a true no-date mechanical movement, nothing interrupts the harmony of the stone dial.
The Founders Collection
Crisp architectural contrast between cool brushed-and-polished surgical steel and the organic warmth of honed pale-beige Jerusalem stone. Powered by the ultra-thin Japanese Miyota 9039 automatic caliber.
Finished in warm yellow gold PVD with matching golden Dauphine hands and applied markers that echo the sunlit tones of Jerusalem stone. Powered by the Swiss-made Sellita SW200-1b automatic caliber.
