<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.

<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.

Safirglass med ditt valg av Blå AR-, Klar AR- eller Uten AR-belegg, skrukrone og 100 m vanntetthet når den er korrekt montert. Kompatibel med NH35-, NH38-, NH70-, NH71- og NH72-urverk. Inkluderer en mellomring for 30,8 mm urskiver.

Kompatibilitet
Urverk: NH35, NH38, NH70, NH71, NH72 — alle passer uten modifikasjon. Dette dekker standard trevisere-, skjelett- og GMT-konfigurasjoner fra Seiko NH-familien.
Urskiver: 30,8 mm urskiver passer med den inkluderte mellomringen. 31,8 mm urskiver passer direkte uten mellomring. De fleste Royal Oak-urskiver i Nomods-katalogen er 30,8 mm og designet for denne kassen.
Visere: Vi anbefaler et lengre visersett for 41 mm-urskiveåpningen — visere i standardlengde som er designet for mindre kasser kan se underdimensjonerte ut. Se anbefalte deler for denne kassen for testede viseralternativer.

Hvorfor vi valgte denne kassen
Royal Oak 41mm er den mest populære kassen i integrert stil i Seiko-moddingmiljøet, og med god grunn. Den oktagonale bezel-geometrien er skarp og presis, med vekslende børstede og polerte overflater som skaper ekte dybde i skiftende lys. Den polerte minuttringen tilfører en ring av lysstyrke mellom urskiven og bezelen som de fleste ettermarkedskasser i denne prisklassen utelater helt. Vi testet dimensjonal nøyaktighet på tvers av produksjonspartier og bekreftet at kronejustering, glasspassform og pakningstilpasning er konsistente. Dette er en rimelig inngang til et 41 mm Royal Oak-bygg med safirglass og 100 m vanntetthet.
Ofte stilte spørsmål
Hvilke urverk passer i Royal Oak 41mm-kassen?
NH35, NH38, NH70, NH71 og NH72 passer alle uten modifikasjon. Disse dekker standard automatiske, skjelett- og open-heart-konfigurasjoner. Kassen er designet rundt dimensjonene til Seiko NH-urverkfamilien.
Hvilken urskivestørrelse passer i denne kassen?
30,8 mm urskiver passer med den inkluderte mellomringen. 31,8 mm urskiver passer direkte uten mellomring. De fleste Nomods Royal Oak-urskiver er 30,8 mm og designet for å passe med denne kassen.
Er denne kassen vanntett?
Kassen er klassifisert til 100 m vanntetthet når den er korrekt montert med alle pakninger riktig på plass og skrukronen fullt iskrudd. Hvis du planlegger å senke klokken under vann, anbefaler vi å få det ferdige bygget trykktestet av en urmaker.
Hvilket visersett bør jeg bruke med 41mm-kassen?
Vi anbefaler lengre visere designet for større urskiver. Visere i standardlengde bygget for 28,5 mm urskiver vil se underdimensjonerte ut mot 41 mm-urskiveåpningen. Royal Oak-viserne i Nomods-katalogen er dimensjonert for denne kassen.
