<p>The Silver Index Royal Oak dial in 28.5 mm — a clean, sunburst-finished skeleton dial designed by Nomods for open-heart and skeleton Seiko builds. The silver index markers frame the movement visible beneath, letting the mechanical architecture of the NH70, NH71, or NH72 become part of the dial’s visual design. At just 0.4 mm thick, the dial sits flush inside the Royal Oak 37mm V2 case and the Petrichor case without any modification. C3 Super-LumiNova applied to each index ensures legibility in low light.</p><h2>Specifications</h2><table><thead><tr><th>Specification</th><th>Value</th></tr></thead><tbody><tr><td>Diameter</td><td>28.5 mm</td></tr><tr><td>Thickness</td><td>~0.4 mm</td></tr><tr><td>Compatible Movements</td><td>NH70, NH71, NH72</td></tr><tr><td>Compatible Cases</td><td>Royal Oak 37mm V2, Petrichor</td></tr><tr><td>Material</td><td>Stainless steel with silver finish</td></tr><tr><td>Lume</td><td>C3 Super-LumiNova</td></tr><tr><td>Design</td><td>Index dial for skeleton/open-heart movements</td></tr></tbody></table><h2>Compatibility</h2><p><strong>Movements:</strong> This dial is designed primarily for skeleton and open-heart movements — the NH70, NH71, and NH72.

<p>The Rose Gold Index Royal Oak dial in 28.5 mm — warm, pinkish-gold index markers over an open skeleton layout designed by Nomods for the NH70, NH71, and NH72 movements. The rose gold finish catches light with a softer warmth than yellow gold, adding a refined accent to the exposed mechanical architecture beneath the dial. At 0.4 mm thick, this dial drops directly into the Royal Oak 37mm V2 case and the Petrichor case without modification.

<p>The Gold Skeleton Royal Oak dial in 28.5 mm — an open-cut design with gold-finished markers that lets the full mechanical architecture of the NH70, NH71, or NH72 skeleton movement show through from the dial side.

La esfera Royal Oak de índices plata en 28,5 mm: una esfera esqueleto limpia, con acabado sunburst, diseñada por Nomods para builds Seiko de corazón abierto y esqueleto. Los marcadores de índice plata enmarcan el movimiento visible debajo, dejando que la arquitectura mecánica del NH70, NH71 o NH72 forme parte del diseño visual de la esfera. Con solo 0,4 mm de grosor, la esfera queda enrasada dentro de la caja Royal Oak 37mm V2 y la caja Petrichor, sin ninguna modificación. El C3 Super-LumiNova aplicado a cada índice asegura la legibilidad con poca luz.
Especificaciones
| Especificación | Valor |
|---|---|
| Diámetro | 28,5 mm |
| Grosor | ~0,4 mm |
| Movimientos compatibles | NH70, NH71, NH72 |
| Cajas compatibles | Royal Oak 37mm V2, Petrichor |
| Material | Acero inoxidable con acabado plata |
| Luminiscencia | C3 Super-LumiNova |
| Diseño | Esfera de índices para movimientos esqueleto / corazón abierto |
Compatibilidad
Movimientos: Esta esfera está diseñada principalmente para movimientos esqueleto y de corazón abierto — el NH70, NH71 y NH72. El centro abierto de la esfera revela los puentes, el rotor y el volante del movimiento. Los movimientos estándar como el NH35 o el NH36 no son compatibles, ya que tienen un lado de esfera macizo sin detalle mecánico visible.
Cajas: El diámetro de 28,5 mm encaja directamente en la caja Royal Oak 37mm V2 y en la caja Petrichor. No encaja en la caja Royal Oak 41mm ni en la caja Seikonaut — estas requieren una esfera de 30,8 mm.

Qué incluye
- Esfera esqueleto de índices plata (28,5 mm)
El movimiento, las agujas, la caja y las herramientas no están incluidos.
Diseñado por Nomods
Esta esfera es un diseño original de Nomods — no una pieza de posventa genérica. Los marcadores de índice plata están mecanizados y acabados con precisión para complementar la geometría angular de la caja Royal Oak. Cada índice se ilumina individualmente con C3 Super-LumiNova para un brillo uniforme en las doce posiciones. La arquitectura abierta de la esfera está concebida para enmarcar los puentes y el volante del movimiento NH70/NH72 como un elemento visual deliberado, en lugar de simplemente retirar material. El resultado es una esfera que se integra con el movimiento esqueleto para crear una cara de reloj en capas, tridimensional.
Preguntas frecuentes
¿Qué cajas encajan con esta esfera?
El diámetro de 28,5 mm encaja directamente en la caja Royal Oak 37mm V2 y en la caja Petrichor. No encaja en la caja Royal Oak 41mm ni en la Seikonaut, que requieren esferas de 30,8 mm.
¿Qué movimientos son compatibles?
Los movimientos esqueleto NH70, NH71 y NH72. Estos son los únicos movimientos Seiko con una arquitectura abierta que hace visible el detalle mecánico a través de la esfera. Los movimientos estándar como el NH35 o el NH36 no funcionarán con esta esfera.
¿Puedo usar esta esfera con un NH35?
No. El NH35 es un movimiento automático estándar con un lado de esfera macizo — no hay nada que ver a través de las secciones abiertas de esta esfera. Necesita un movimiento esqueleto NH70, NH71 o NH72, diseñado para verse desde el lado de la esfera.
¿Cuál es la diferencia entre las esferas de 28,5 mm y 30,8 mm?
Las esferas de 28,5 mm encajan en cajas más pequeñas como la Royal Oak 37mm V2 y la Petrichor. Las esferas de 30,8 mm encajan en cajas más grandes como la Royal Oak 41mm y la Seikonaut. Los dos tamaños no son intercambiables. Lea nuestra guía completa de tamaños de esfera para más detalles.
