{"product_id":"royal-oak-41mm-case","title":"Royal Oak 41mm Case","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e41 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLug-to-Lug\u003c\/td\u003e\n\u003ctd\u003e51 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThickness\u003c\/td\u003e\n\u003ctd\u003e12.6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e316L Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eBrushed mid-case, polished rehaut and bezel bevels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrystal\u003c\/td\u003e\n\u003ctd\u003eSapphire (Blue AR \/ Clear AR \/ No AR)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Resistance\u003c\/td\u003e\n\u003ctd\u003e100 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Fit\u003c\/td\u003e\n\u003ctd\u003e30.8–31.8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLug Width\u003c\/td\u003e\n\u003ctd\u003e22 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrown\u003c\/td\u003e\n\u003ctd\u003eScrew-down, included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eMovements:\u003c\/strong\u003e NH35, NH38, NH70, NH71, NH72 — all drop in without modification.

The octagonal bezel geometry is sharp and precise, with alternating brushed and polished surfaces that create real depth under changing light. The polished rehaut adds a ring of brightness between the dial and bezel that most aftermarket cases at this price skip entirely. We tested dimensional accuracy across production batches and confirmed that crown alignment, crystal seating, and gasket fit are consistent. This is an affordable entry into a 41 mm Royal Oak build with sapphire crystal and 100 m water resistance.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv itemscope itemtype=\"https:\/\/schema.org\/FAQPage\"\u003e\n\u003cdiv itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\"\u003e\n\u003ch3 itemprop=\"name\"\u003eWhat movements fit the Royal Oak 41mm case?\u003c\/h3\u003e\n\u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\u003cp itemprop=\"text\"\u003eThe NH35, NH38, NH70, NH71, and NH72 all fit without modification.
