Seiko Mod Dials

About

24 watch dials in two sizes: 28.5 mm for Royal Oak 37 mm and Petrichor cases, and 30.8 mm for Seikonaut / Nautilus Ultra-Thin and Royal Oak 41 mm cases. Choose from skeleton dials that expose the movement, polished index dials with applied markers, and textured waffle dials with a metallic finish. Skeleton dials require an NH70, NH71, or NH72 movement; solid and waffle dials work with NH35, NH36, and all other NH-series calibers. Movement compatibility: Skeleton dials (cutout center) must be paired with NH70, NH71, or NH72 skeleton movements. Solid dials, index dials, and waffle dials work with any NH-series movement including NH35, NH36, NH38, and NH34 GMT. Dial fit: 28.5 mm dials fit Royal Oak 37 mm V2 and Petrichor cases. 30.8 mm dials fit Seikonaut / Nautilus Ultra-Thin and Royal Oak 41 mm cases. Read the complete dial size guide before ordering. Watch out: Dial size is the number one mistake new builders make. A 28.5 mm dial will not fit a 30.8 mm case opening and vice versa. Always confirm your case platform before choosing a dial. How to Choose Your Dial Size first — this is the most important decision: Measure your case or check the product listing. If you have a Royal Oak 37 mm V2 or Petrichor, you need a 28.5 mm dial. If you have a Seikonaut or Royal Oak 41 mm, you need a 30.8 mm dial. A wrong-size dial will not physically fit, and dials cannot be returned once the protective film is removed. Skeleton vs. solid: Skeleton dials have an open center that reveals the movement’s balance wheel, gears, and bridges. They create a more mechanical, intricate look but require an NH70, NH71, or NH72 movement — standard NH35/NH36 movements have a solid rotor that looks unfinished through a skeleton cutout. Solid dials (index, waffle, sunburst) offer a cleaner, more traditional watch face and work with every movement in the lineup. Color matching: For a cohesive build, match your dial finish to your case and hands. Silver dials pair naturally with silver and gunmetal ca
