{"product_id":"petrichor-37mm-case","title":"Petrichor 37mm Case","description":"\u003cp\u003eThe Silver Petrichor is a Nomods original — not a homage to any existing watch, but a design language we developed from scratch. Inspired by the flowing curves of 1960s and 1970s vintage watchmaking, the Petrichor case features soft, organic lines that set it apart from the angular profiles dominating the mod scene. Machined from 316L stainless steel with a brushed silver finish, fitted with a domed sapphire crystal, and sized at 37 mm for a refined wrist presence. Compatible with NH35 and NH36 movements, this case is ready for your next build.\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\u003e37 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 silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrystal\u003c\/td\u003e\n\u003ctd\u003eDomed sapphire (pre-installed)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMovement Compatibility\u003c\/td\u003e\n\u003ctd\u003eNH35, NH36\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Fit\u003c\/td\u003e\n\u003ctd\u003e28.5 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\u003ctr\u003e\n\u003ctd\u003eBracelet\u003c\/td\u003e\n\u003ctd\u003eIntegrated stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Resistance\u003c\/td\u003e\n\u003ctd\u003eDepends on proper gasket installation during assembly\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 and NH36.

We did not set out to replicate an existing watch — we wanted to create something that felt like it could have come from the golden era of case design in the 1960s and 1970s, when curves were generous and cases hugged the wrist. The domed sapphire crystal is central to this vision: instead of a tall, flat crystal sitting above a deep rehaut, the dome follows the case contour, keeping the overall profile slim. Every case is individually checked for finishing quality — brushing consistency, edge sharpness, and crystal seating — before shipping.\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 Petrichor case?\u003c\/h3\u003e\n\u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\u003cp itemprop=\"text\"\u003eThe Petrichor is designed for the NH35 and NH36 movements.

It does not replicate the Royal Oak, Nautilus, or any other existing watch. The design draws inspiration from the broad aesthetic movement of 1960s and 1970s vintage watchmaking — an era defined by flowing curves and integrated case designs — but the Petrichor’s specific lines, proportions, and details are entirely our own.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2\u003eComplete Your Build\u003c\/h2\u003e\n\u003cp\u003ePair the Silver Petrichor case with these compatible components:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/en-gb\/products\/nh35-movement\"\u003eNH35 Movement\u003c\/a\u003e — the recommended automatic movement for this case\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/en-gb\/products\/royal-oak-skeleton-dial-v1-28-5mm-silver\"\u003eSilver Royal Oak 28.5mm Dial\u003c\/a\u003e — matches the brushed silver case finish\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/en-gb\/products\/waffle-dial-28-5mm\"\u003eSilver-White Waffle Dial (28.5mm)\u003c\/a\u003e — textured dial with a light, clean look\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/en-gb\/products\/royal-oak-hands-v2-silver\"\u003eSilver V2 Hands\u003c\/a\u003e — brushed silver hands to match the case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBrowse Collection\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"\/en-gb\/collections\/petrichor-style-parts\"\u003ePetrichor 37mm Seiko Mod Parts\u003c\/a\u003e · \u003ca href=\"\/en-gb\/collections\/seiko-mod-cases\"\u003eAll Seiko Mod Cases\u003c\/a\u003e · \u003ca href=\"\/en-gb\/collections\/petrichor-case\"\u003ePetrichor Watch Modding Case\u003c\/a\u003e · \u003ca href=\"\/en-gb\/collections\/seiko-mod-petrichor-37mm\"\u003eSeiko Mod Petrichor 37mm\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eNomods is an independent brand.
