<p>The Silver Index Skeleton dial in 30.8 mm — a larger-format skeleton dial designed by Nomods for the Royal Oak 41mm case and the Seikonaut case. Silver indexes frame the full mechanical architecture of the NH70, NH71, or NH72 skeleton movement, providing clear time reading over a background of moving bridges, balance wheel, and rotor. The 30.8 mm diameter is purpose-built for 41 mm case platforms where a 28.5 mm dial would leave an exposed gap. C3 Super-LumiNova on all markers for low-light legibility.</p><h2>Specifications</h2><table><thead><tr><th>Specification</th><th>Value</th></tr></thead><tbody><tr><td>Diameter</td><td>30.8 mm</td></tr><tr><td>Compatible Movements</td><td>NH70, NH71, NH72</td></tr><tr><td>Compatible Cases</td><td>Royal Oak 41mm, Seikonaut</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>Skeleton / open-cut with index markers</td></tr></tbody></table><h2>Compatibility</h2><p><strong>Movements:</strong> Requires a skeleton or open-heart movement — the NH70, NH71, or NH72.

The 30.8 mm diameter fills the larger dial opening of the 41mm case properly — standard 28.5 mm dials would leave an exposed ring around the edge. The silver index markers are machined to the same angular standard as our 28.5 mm Royal Oak dials, scaled up proportionally for the bigger case. Each index carries C3 Super-LumiNova for consistent glow across all twelve positions. The skeleton architecture maximises the visible area of the NH70/NH72 movement while keeping the indexes structurally rigid and precisely aligned.</p><h2>Frequently Asked Questions</h2><div itemscope itemtype="https://schema.org/FAQPage"><div itemscope itemprop="mainEntity" itemtype="https://schema.org/Question"><h3 itemprop="name">What cases fit this dial?</h3><div itemscope itemprop="acceptedAnswer" itemtype="https://schema.org/Answer"><p itemprop="text">The 30.8 mm diameter fits the Royal Oak 41mm case (with the included spacer ring) and the Seikonaut case directly.

<p>The Rose Gold Skeleton dial in 30.8 mm — warm, copper-pink markers over an open skeleton layout designed by Nomods for the Royal Oak 41mm case and the Seikonaut case. The rose gold finish brings a softer warmth than yellow gold, producing an inviting contrast against the steel-toned bridges and rotor of the NH70, NH71, or NH72 skeleton movement visible beneath.

<p>The Gold Index Skeleton dial in 30.8 mm — bold, warm yellow-gold markers over an open skeleton layout designed by Nomods for the Royal Oak 41mm case and the Seikonaut case. The gold finish transforms the angular index markers into luminous accents that catch light from every angle, creating visual depth and warmth against the exposed steel bridges and rotor of the NH70, NH71, or NH72 skeleton movement.

La esfera esqueleto de índices plata en 30,8 mm: una esfera esqueleto de formato grande diseñada por Nomods para la caja Royal Oak 41mm y la caja Seikonaut. Los índices plata enmarcan la arquitectura mecánica completa del movimiento esqueleto NH70, NH71 o NH72, ofreciendo una lectura clara de la hora sobre un fondo de puentes en movimiento, volante y rotor. El diámetro de 30,8 mm está concebido específicamente para plataformas de caja de 41 mm donde una esfera de 28,5 mm dejaría un hueco expuesto. C3 Super-LumiNova en todos los marcadores para la legibilidad con poca luz.
Especificaciones
| Especificación | Valor |
|---|---|
| Diámetro | 30,8 mm |
| Movimientos compatibles | NH70, NH71, NH72 |

| Material | Acero inoxidable con acabado plata |
| Luminiscencia | C3 Super-LumiNova |
| Diseño | Esqueleto / calado con marcadores de índice |
Compatibilidad
Movimientos: Requiere un movimiento esqueleto o de corazón abierto — el NH70, NH71 o NH72. Las secciones abiertas de la esfera están diseñadas para mostrar la arquitectura mecánica del movimiento desde el frente. Los movimientos estándar como el NH35 o el NH36 no mostrarán ningún detalle visible a través de las aberturas del esqueleto.
Cajas: El diámetro de 30,8 mm encaja directamente en la caja Royal Oak 41mm (con el anillo espaciador incluido con la caja) y en la caja Seikonaut. No encaja en la Royal Oak 37mm V2 ni en la Petrichor — estas requieren una esfera de 28,5 mm.

Qué incluye
- Esfera esqueleto de índices plata (30,8 mm)
El movimiento, las agujas, la caja, el anillo espaciador y las herramientas no están incluidos. El anillo espaciador se incluye con la caja Royal Oak 41mm.
Diseñado por Nomods
Esta esfera es un diseño original de Nomods creado específicamente para la plataforma de caja Royal Oak de 41 mm. El diámetro de 30,8 mm rellena correctamente la mayor apertura de esfera de la caja de 41mm — las esferas estándar de 28,5 mm dejarían un anillo expuesto en el borde. Los marcadores de índice plata están mecanizados con el mismo estándar angular que nuestras esferas Royal Oak de 28,5 mm, ampliados proporcionalmente para la caja más grande. Cada índice lleva C3 Super-LumiNova para un brillo uniforme en las doce posiciones. La arquitectura esqueleto maximiza el área visible del movimiento NH70/NH72 manteniendo al mismo tiempo los índices estructuralmente rígidos y alineados con precisión.
Preguntas frecuentes
¿Qué cajas encajan con esta esfera?
El diámetro de 30,8 mm encaja directamente en la caja Royal Oak 41mm (con el anillo espaciador incluido) y en la caja Seikonaut. No encaja en la Royal Oak 37mm V2 ni en la Petrichor, que requieren esferas de 28,5 mm.
¿Qué movimientos son compatibles?
Los movimientos esqueleto NH70, NH71 y NH72. Estos son los únicos movimientos Seiko NH con una arquitectura abierta visible desde el lado de la esfera. Los movimientos estándar como el NH35 tienen una platina maciza y no están diseñados para esferas esqueleto.
¿Puedo usar esta esfera con un NH35?
No. El NH35 tiene un lado de esfera macizo sin detalle mecánico expuesto. Esta esfera esqueleto está diseñada para el NH70, NH71 o NH72, donde los puentes y el volante del movimiento son visibles desde el frente.
¿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 tamaños no son intercambiables. Consulte nuestra guía de tamaños de esfera para la comparación completa.
