Sunburst Sector Dial 28.5mm – Blue / Black / Green

A sunburst sector dial with a radial chapter ring pattern, available in blue, black, and green. The sector design divides the dial face into distinct zones with raised radial lines that catch light at different angles, creating a structured, architectural look that stands apart from both plain sunburst and waffle textures. At 28.5 mm diameter, this dial fits the Royal Oak 37mm V2 and Petrichor 37mm cases. Unlike most dials in our range, the sector dial is compatible with every Seiko NH-family movement — NH35, NH36, NH38, NH70, NH71, and NH72 — making it one of the most versatile dial options available. C3 Super-LumiNova on the markers and hands ensures legibility in low light. Choose between blue sunburst, black sunburst, or green sunburst to match your build.

About the Sector Dial

The sector dial is a vintage-inspired design that references the radial chapter ring layouts popular on dress watches from the 1930s and 1940s. Instead of a uniform dial face, the sector pattern divides the surface into radiating segments that create a distinct visual rhythm around the dial. Each segment catches light at a slightly different angle thanks to the sunburst finishing underneath, so the dial appears to shift between light and dark zones as the wrist moves. The three color options — blue, black, and green — each offer a different character: the blue reads as refined and contemporary, the black is classic and versatile, and the green adds a subtle color accent that only reveals itself in direct light.
