The Sartory-Billard SB04-E Pietersite Platinum is a limited edition of just 50 pieces, with deliveries starting from July 2025. This distinctive 43.5 mm watch features a mesmerizing dial made from Pietersite, a natural stone known for its swirling patterns and storm-like appearance. With deep blues, gold, and bronze hues, the dial evokes a storm frozen in time, and each dial is completely unique.

Surrounding the dial is a platinum-coated outer ring with a sunburst texture and soft gradient, highlighting the dynamic character of the Pietersite. The watch features a sapphire disk with applied hour markers, including a faceted and polished metal inner ring, diamond-cut indexes, and the signature Y-shaped design in Super-LumiNova® BGW9, inspired by the Eiffel Tower and the founder’s Parisian heritage.

The slender, diamond-cut hands are linearly brushed and filled with BGW9 Super-LumiNova®, creating a playful interplay with light and a sense of depth and elegance. The concave bezel creates an optical illusion that makes the case appear slimmer and brings the dial closer to the wearer. The case combines polished and brushed surfaces with refined faceted edges.

The SB04-E is powered by a high-quality automatic movement, combining craftsmanship with technical perfection. The screw-down crown features circular brushing and is filled with glowing BGW9 Super-LumiNova®, ensuring water resistance up to 100 meters.

This model is fitted with a 20 mm wide grey-blue ostrich leather strap, giving the watch an elegant and unique look.

The Pietersite dial is responsibly and sustainably crafted in Germany. This makes each SB04-E not only a technical masterpiece but also a personal artwork that captures the power and beauty of nature.
