<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. Includes a spacer ring for 30.8 mm dials.</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. Includes spacer ring for 30.8 mm dials.</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.

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. Includes spacer ring for 30.8 mm dials.</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.

<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. Fits NH35, NH38, NH70, NH71, and NH72 movements. Includes a spacer ring for 30.8 mm dials.</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 black PVD coating</td></tr><tr><td>Finish</td><td>Matte black PVD, 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.

Le diamètre de 41 mm repose avec assurance sur les poignets de 17 cm et plus.

Compatible avec les mouvements NH35, NH38, NH70, NH71 et NH72. Inclut une bague d'espacement pour les cadrans de 30,8 mm.

Pourquoi nous avons choisi ce boîtier
Le Royal Oak 41mm est le boîtier au style intégré le plus populaire de la communauté du modding Seiko, et ce pour de bonnes raisons. La géométrie octogonale de la lunette est nette et précise, avec des surfaces alternant brossées et polies qui créent une réelle profondeur sous une lumière changeante. Le rehaut poli ajoute un anneau de clarté entre le cadran et la lunette que la plupart des boîtiers d'après-vente à ce prix omettent entièrement. Nous avons testé la précision dimensionnelle sur plusieurs lots de production et confirmé que l'alignement de la couronne, le logement du verre et l'ajustement des joints sont constants. C'est une entrée abordable dans un build Royal Oak 41 mm avec verre saphir et étanchéité 100 m.
Questions fréquentes
Quels mouvements s'adaptent au boîtier Royal Oak 41mm ?
Les NH35, NH38, NH70, NH71 et NH72 s'adaptent tous sans modification. Ils couvrent les configurations automatique standard, squelette et cœur ouvert. Le boîtier est conçu autour des dimensions de la famille de mouvements Seiko NH.
Quelle taille de cadran s'adapte à ce boîtier ?
Les cadrans de 30,8 mm s'adaptent avec la bague d'espacement incluse. Les cadrans de 31,8 mm s'adaptent directement sans la bague. La plupart des cadrans Royal Oak Nomods font 30,8 mm et sont conçus pour s'associer à ce boîtier.
Ce boîtier est-il étanche ?
Le boîtier est étanche à 100 m lorsqu'il est assemblé correctement, avec tous les joints bien en place et la couronne vissée entièrement engagée. Si vous prévoyez d'immerger la montre, nous recommandons de faire effectuer un test de pression du build terminé par un horloger.
Quel jeu d'aiguilles dois-je utiliser avec le boîtier 41mm ?
Nous recommandons des aiguilles plus longues conçues pour les grands cadrans. Les aiguilles de longueur standard conçues pour des cadrans de 28,5 mm paraîtront sous-dimensionnées face à l'ouverture de cadran de 41 mm. Les aiguilles Royal Oak du catalogue Nomods sont dimensionnées pour ce boîtier.
