SB04-E Pietersite Platinum

Sartory-Billard SB04-E Pietersite Platinum is a 50-piece limited edition that combines natural stone dial craftsmanship with the refined, contemporary proportions of the SB04-E case. Its dial is centred on Pietersite, a natural stone known for storm-like swirling patterns in deep blue, gold and bronze tones. Each dial is individually cut and finished, meaning no two examples are identical. Surrounding the stone centre is a fumé platinum-coated outer ring with sunburst finishing, creating contrast while enhancing the depth and movement of the natural material.

A 0.3 mm sapphire disk sits above the minute dial, carrying diamond-cut metal indexes and the brand’s Y-shaped minute track, printed with white Super-LumiNova BGW9 for blue emission in low light. Slender diamond-cut hands, also filled with BGW9 Super-LumiNova, complete the display. The 39.5 mm stainless steel case measures 10.3 mm thick and 46 mm lug-to-lug, with alternating brushed and polished surfaces, a concave bezel and a screw-down lumed crown. Water resistance is rated to 100 metres.

Power comes from the La Joux-Perret G101 automatic calibre, featuring a tungsten rotor, 24 jewels, 4 Hertz frequency and a 68-hour power reserve. Supplied on a 20 mm curved strap, the SB04-E Pietersite Platinum offers a distinctive balance of independent design, natural dial character and everyday wearability.
