{"product_id":"seiko-mod-petrichor-37mm-skeleton","title":"Petrichor 37mm Skeleton","description":"\u003cp\u003eMonochrome silver from case to bracelet — the Petrichor 37mm Silver skeleton is the most understated watch in the Petrichor range. The NH72 automatic movement is visible through both the open skeleton dial and the exhibition caseback, giving you two viewing angles on the same mechanics. A domed sapphire crystal adds optical depth, curving light across the exposed bridges and gears beneath. At 37 mm across and 11.6 mm thick, this is a deliberately slim build — vintage sizing with a modern skeleton heart. Brushed 316L stainless steel, integrated bracelet, 100 m water resistance. Fully assembled.\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\u003eMovement\u003c\/td\u003e\n\u003ctd\u003eSeiko NH72 (skeleton, automatic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Reserve\u003c\/td\u003e\n\u003ctd\u003eApprox. 41 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Material\u003c\/td\u003e\n\u003ctd\u003e316L Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Finish\u003c\/td\u003e\n\u003ctd\u003eBrushed silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Accents\u003c\/td\u003e\n\u003ctd\u003eSilver hands and indexes (monochrome)\u003c\/td\u003e\n\u003c\/tr\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\u003eThickness\u003c\/td\u003e\n\u003ctd\u003e11.6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrystal\u003c\/td\u003e\n\u003ctd\u003eDomed sapphire\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\u003eCaseback\u003c\/td\u003e\n\u003ctd\u003eExhibition (display)\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\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis is a fully assembled watch.

The silver monochrome variant is the purest expression of that design: no two-tone contrast, no color accents, just brushed steel and the raw mechanics of the NH72 movement as the only visual feature on the dial. The domed sapphire crystal was chosen specifically because its curved surface catches and bends light, adding depth to the skeleton dial that a flat crystal cannot replicate. At 37 mm with an 11.6 mm thickness, the Petrichor sits closer to vintage dress watch proportions than most modern skeletons — intentionally designed to wear quietly on the wrist while revealing everything through the glass.\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\"\u003eIs 37 mm too small for a men’s watch?\u003c\/h3\u003e\n\u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\u003cp itemprop=\"text\"\u003e37 mm is a classic men’s watch diameter — the same size worn by most dress watches throughout the 20th century.

It also catches light from more angles, producing reflections that change as you move your wrist. Flat sapphire is flush with the bezel and offers a cleaner, more utilitarian look. The Petrichor uses domed sapphire because the added depth complements the layered architecture of the NH72 skeleton movement.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\"\u003e\n\u003ch3 itemprop=\"name\"\u003eCan I swap the movement or dial on the Petrichor?\u003c\/h3\u003e\n\u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\u003cp itemprop=\"text\"\u003eYes.
