<p>The Silver Royal Oak 41mm is the largest integrated-design case in the Nomods lineup — bold wrist presence without the price tag of a full build. CNC-machined from 316L stainless steel with an octagonal bezel, polished rehaut, and brushed mid-case, this case captures the finishing language of luxury integrated-bracelet sports watches. The 41 mm diameter sits confidently on wrists 17 cm and above. Sapphire crystal in your choice of Blue AR, Clear AR, or No AR coating, screw-down crown, and 100 m water resistance when assembled correctly. Compatible with NH35, NH38, NH70, NH71, and NH72 movements.</p><h2>Specifications</h2><table><thead><tr><th>Specification</th><th>Value</th></tr></thead><tbody><tr><td>Diameter</td><td>41 mm</td></tr><tr><td>Lug-to-Lug</td><td>51 mm</td></tr><tr><td>Thickness</td><td>12.2 mm (11.6 mm without crystal)</td></tr><tr><td>Material</td><td>316L Stainless Steel</td></tr><tr><td>Finish</td><td>Brushed mid-case, polished rehaut and bezel bevels</td></tr><tr><td>Crystal</td><td>Sapphire (Blue AR / Clear AR / No AR)</td></tr><tr><td>Water Resistance</td><td>100 m</td></tr><tr><td>Dial Fit</td><td>30.8–31.8 mm</td></tr><tr><td>Lug Width</td><td>22 mm</td></tr><tr><td>Crown</td><td>Screw-down, included</td></tr></tbody></table><h2>Compatibility</h2><p><strong>Movements:</strong> NH35, NH38, NH70, NH71, NH72 — all drop in without modification.

<p>The Rose Gold Royal Oak 41mm brings a warm, refined finish to the largest integrated-design case in the Nomods catalog. The rose gold coating over 316L stainless steel catches light with a subtle pink-gold warmth that pairs naturally with rose gold dials and hands. At 41 mm with a 51 mm lug-to-lug span, this case delivers bold wrist presence while the 12.2 mm thickness keeps the profile controlled. The octagonal bezel features brushed flats and polished bevels, with a polished rehaut that frames the dial. Sapphire crystal in Blue AR, Clear AR, or No AR, screw-down crown, and 100 m water resistance. Fits NH35, NH38, NH70, NH71, and NH72 movements.</p><h2>Specifications</h2><table><thead><tr><th>Specification</th><th>Value</th></tr></thead><tbody><tr><td>Diameter</td><td>41 mm</td></tr><tr><td>Lug-to-Lug</td><td>51 mm</td></tr><tr><td>Thickness</td><td>12.2 mm (11.6 mm without crystal)</td></tr><tr><td>Material</td><td>316L Stainless Steel with rose gold finish</td></tr><tr><td>Finish</td><td>Brushed mid-case, polished rehaut and bezel bevels</td></tr><tr><td>Crystal</td><td>Sapphire (Blue AR / Clear AR / No AR)</td></tr><tr><td>Water Resistance</td><td>100 m</td></tr><tr><td>Dial Fit</td><td>30.8–31.8 mm</td></tr><tr><td>Lug Width</td><td>22 mm</td></tr><tr><td>Crown</td><td>Screw-down, included</td></tr></tbody></table><h2>Compatibility</h2><p><strong>Movements:</strong> NH35, NH38, NH70, NH71, NH72 — all drop in without modification.

The Royal Oak 41mm Rose Gold uses a coating process that holds up through daily wear. The rose gold shade was selected to complement the warm champagne tones of the NH72’s bridges, so skeleton builds look cohesive from bezel to movement. Even with an NH35 and a solid dial, the rose gold case adds warmth that natural steel cannot replicate. The polished rehaut provides a bright ring of contrast against the rose gold surfaces, adding depth to the dial window.</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 movements fit the Royal Oak 41mm case?</h3><div itemscope itemprop="acceptedAnswer" itemtype="https://schema.org/Answer"><p itemprop="text">The NH35, NH38, NH70, NH71, and NH72 all fit without modification.

<p>The Rose Gold Royal Oak 41mm brings a warm, refined finish to the largest integrated-design case in the Nomods catalog. The rose gold coating over 316L stainless steel catches light with a subtle pink-gold warmth that pairs naturally with rose gold dials and hands. At 41 mm with a 51 mm lug-to-lug span, this case delivers bold wrist presence while the 12.2 mm thickness keeps the profile controlled. The octagonal bezel features brushed flats and polished bevels, with a polished rehaut that frames the dial. Sapphire crystal in Blue AR, Clear AR, or No AR, screw-down crown, and 100 m water resistance. Fits NH35, NH38, NH70, NH71, and NH72 movements.</p><h2>Specifications</h2><table><thead><tr><th>Specification</th><th>Value</th></tr></thead><tbody><tr><td>Diameter</td><td>41 mm</td></tr><tr><td>Lug-to-Lug</td><td>51 mm</td></tr><tr><td>Thickness</td><td>12.2 mm (11.6 mm without crystal)</td></tr><tr><td>Material</td><td>316L Stainless Steel with rose gold finish</td></tr><tr><td>Finish</td><td>Brushed mid-case, polished rehaut and bezel bevels</td></tr><tr><td>Crystal</td><td>Sapphire (Blue AR / Clear AR / No AR)</td></tr><tr><td>Water Resistance</td><td>100 m</td></tr><tr><td>Dial Fit</td><td>30.8–31.8 mm</td></tr><tr><td>Lug Width</td><td>22 mm</td></tr><tr><td>Crown</td><td>Screw-down, included</td></tr></tbody></table><h2>Compatibility</h2><p><strong>Movements:</strong> NH35, NH38, NH70, NH71, NH72 — all drop in without modification.

The Royal Oak 41mm Rose Gold uses a coating process that holds up through daily wear. The rose gold shade was selected to complement the warm champagne tones of the NH72’s bridges, so skeleton builds look cohesive from bezel to movement. Even with an NH35 and a solid dial, the rose gold case adds warmth that natural steel cannot replicate. The polished rehaut provides a bright ring of contrast against the rose gold surfaces, adding depth to the dial window.</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 movements fit the Royal Oak 41mm case?</h3><div itemscope itemprop="acceptedAnswer" itemtype="https://schema.org/Answer"><p itemprop="text">The NH35, NH38, NH70, NH71, and NH72 all fit without modification.

<p>The Black PVD Royal Oak 41mm is the stealth option in the 41 mm range — the same sharp octagonal bezel geometry and polished rehaut as the silver version, now in a matte black PVD coating over 316L stainless steel. The black finish absorbs light across the brushed mid-case while the polished bezel bevels and rehaut provide controlled reflections that define the case shape. At 41 mm diameter with a 51 mm lug-to-lug span, this is a large, commanding case that wears dark and low-key. Sapphire crystal in Blue AR, Clear AR, or No AR, screw-down crown, and 100 m water resistance.

<p>The Black PVD Royal Oak 41mm is the stealth option in the 41 mm range — the same sharp octagonal bezel geometry and polished rehaut as the silver version, now in a matte black PVD coating over 316L stainless steel. The black finish absorbs light across the brushed mid-case while the polished bezel bevels and rehaut provide controlled reflections that define the case shape. At 41 mm diameter with a 51 mm lug-to-lug span, this is a large, commanding case that wears dark and low-key.

Compatible con los movimientos NH35, NH38, NH70, NH71 y NH72.

Por qué elegimos esta caja
El Royal Oak 41mm es la caja de estilo integrado más popular de la comunidad del modding Seiko, y por buenas razones. La geometría octogonal del bisel es nítida y precisa, con superficies que alternan cepillado y pulido y crean profundidad real bajo una luz cambiante. El rehaut pulido añade un anillo de brillo entre la esfera y el bisel que la mayoría de las cajas de posventa a este precio omiten por completo. Hemos probado la precisión dimensional en varios lotes de producción y confirmado que la alineación de la corona, el asiento del cristal y el ajuste de las juntas son constantes. Esta es una entrada asequible a un build Royal Oak de 41 mm con cristal de zafiro y 100 m de resistencia al agua.
Preguntas frecuentes
¿Qué movimientos encajan en la caja Royal Oak 41mm?
Los NH35, NH38, NH70, NH71 y NH72 encajan todos sin modificación. Estos cubren configuraciones automáticas estándar, esqueleto y de corazón abierto. La caja está diseñada en torno a las dimensiones de la familia de movimientos Seiko NH.
¿Qué tamaño de esfera encaja en esta caja?
La mayoría de las esferas Royal Oak de Nomods son de 30,8 mm y están diseñadas para combinarse con esta caja.
¿Es esta caja resistente al agua?
La caja está clasificada para 100 m de resistencia al agua cuando se ensambla correctamente, con todas las juntas bien asentadas y la corona roscada completamente enroscada. Si planea sumergir el reloj, recomendamos que un relojero realice una prueba de presión del build terminado.
¿Qué juego de agujas debo usar con la caja de 41mm?
