{"product_id":"nh38-movement","title":"NH38 Automatic Movement","description":"\u003cp\u003eThe Seiko NH38 strips the date complication entirely, giving you a clean dial with no window cutout. Manufactured by TMI (Time Module Inc.), a subsidiary of Seiko Instruments, the NH38 belongs to the same movement family as the NH35 and NH36 and shares their 21,600 bph frequency, 24 jewels, 41-hour power reserve, hacking seconds, and hand-winding. Choose the NH38 when your build calls for a minimalist dial design where a date window would disrupt the symmetry.\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\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCaliber\u003c\/td\u003e\n\u003ctd\u003eSeiko NH38A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eAutomatic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e21,600 bph (6 beats per second)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eJewels\u003c\/td\u003e\n\u003ctd\u003e24\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Reserve\u003c\/td\u003e\n\u003ctd\u003e41 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHacking\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHand-Winding\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDate\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStem Position\u003c\/td\u003e\n\u003ctd\u003e3 o’clock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRotor\u003c\/td\u003e\n\u003ctd\u003eBidirectional\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe NH38 shares the same physical dimensions as the NH35 and NH36, so it drops into every Nomods case without modification: Royal Oak 37 mm, Royal Oak 41 mm, Petrichor, and Seikonaut.

When you want a dial with unbroken symmetry — no date window cutting into the indices, no day wheel cluttering the layout — the NH38 is the correct caliber. It shares every mechanical attribute with the NH35 except the date disc, so you are not sacrificing reliability or build quality for a cleaner look. Nomods uses the NH38 in builds where minimalist dial design is the priority, particularly in diver-style and field-style watches where the owner wants time-only display.\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 is the difference between the NH38 and NH35?\u003c\/h3\u003e\n\u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\u003cdiv itemprop=\"text\"\u003e\u003cp\u003eThe only difference is the date complication. The NH35 has a date wheel that displays the date through a window at three o’clock. The NH38 has no date mechanism at all, resulting in a cleaner crown operation (one less position to cycle through) and full freedom to use dials without any cutout. Frequency, jewel count, power reserve, hacking, and hand-winding are all identical.\u003c\/p\u003e\u003c\/div\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 use a dial with a date window on the NH38?\u003c\/h3\u003e\n\u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\u003cdiv itemprop=\"text\"\u003e\u003cp\u003eYou can physically install a date-window dial, but there will be no date disc behind the aperture — you will see a blank space where the date number would normally appear.
