{"product_id":"sunburst-sector-dial-28-5mm","title":"Sunburst Sector Dial 28.5mm – Blue \/ Black \/ Green","description":"\u003cp\u003eA 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.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e28.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Movements\u003c\/td\u003e\n\u003ctd\u003eNH35, NH36, NH38, NH70, NH71, NH72\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Cases\u003c\/td\u003e\n\u003ctd\u003eRoyal Oak 37mm V2, Petrichor 37mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStyle\u003c\/td\u003e\n\u003ctd\u003eSunburst sector (radial chapter ring)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor Options\u003c\/td\u003e\n\u003ctd\u003eBlue, Black, Green\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLume\u003c\/td\u003e\n\u003ctd\u003eC3 Super-LumiNova\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrown Position\u003c\/td\u003e\n\u003ctd\u003e3 o’clock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eMovements:\u003c\/strong\u003e This sector dial is compatible with the full range of Seiko NH-family movements: NH35, NH36, NH38, NH70, NH71, and NH72.

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.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv itemscope itemtype=\"https:\/\/schema.org\/FAQPage\"\u003e\n\u003cdiv itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\"\u003e\n\u003ch3 itemprop=\"name\"\u003eWhat cases fit this dial?\u003c\/h3\u003e\n\u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\u003cp itemprop=\"text\"\u003eThe 28.5 mm diameter fits the Royal Oak 37mm V2 case and the Petrichor 37mm case directly.
