The Seiko NH71 is a gold-plated skeleton movement that brings a warm, luxurious tone to any skeleton build. Manufactured by TMI (Time Module Inc.), a subsidiary of Seiko Instruments, the NH71 features the same open-worked bridge architecture as the NH70 and NH72, but finished in gold plating that catches light beautifully through a skeleton dial. The 21,600 bph frequency, 24 jewels, 41-hour power reserve, hacking, and hand-winding are identical across the entire NH skeleton family. Choose the NH71 when your build pairs with gold-tone cases or when you want the warmest bridge color available. Specifications Specification Detail Caliber Seiko NH71A Type Automatic Skeleton Frequency 21,600 bph (6 beats per second) Jewels 24 Power Reserve 41 hours Hacking Yes Hand-Winding Yes Date No Skeleton Yes (open-worked bridges) Bridge Finish Gold-plated Stem Position 3 o’clock Rotor Bidirectional Compatibility The NH71 fits every Nomods case: Royal Oak 37 mm, Royal Oak 41 mm, Petrichor, and Seikonaut. Like all skeleton movements, it requires a skeleton dial to reveal the gold-plated open-worked bridges. The warm golden tone of the NH71 pairs particularly well with gold PVD cases and gold-accented dials, creating a cohesive warm-tone aesthetic throughout the build. Dial sizes: 28.5 mm skeleton dials for the Royal Oak 37 mm and Petrichor cases · 30.8 mm skeleton dials for the Royal Oak 41 mm and Seikonaut cases Hands: All Nomods hands are compatible with the NH71 skeleton movement. Gold-tone hands complement the gold bridge finish. Crown sits at 3 o’clock. What’s Included Seiko NH71A skeleton movement (fully assembled with rotor) Stem Movement specification sheet Why This Movement The NH71 is the gold option in the skeleton lineup. Where the NH70 offers neutral silver bridges and the NH72 delivers dark, dramatic contrast, the NH71 brings warmth. The gold-plated bridges glow through a skeleton dial, particularly when paired with a gold PVD case where the bridge color and case color complement each other for a unified luxury aesthetic. Nomods uses the NH71 in premium gold skeleton builds — the Royal Oak Gold Skeleton and similar configurations where the customer wants every visible component to share the same warm tone. Frequently Asked Questions How does the NH71 gold finish compare to the NH70 and NH72? All three are mechanically identical skeleton movements with 21,600 bph, 24 jewels, and 41-hour power reserve. The difference is purely the bridge finish: the NH70 has natural silver bridges, the NH71 has gold-plated bridges, and the NH72 has dark-plated (black) bridges. Choose based on the color scheme of your build — gold bridges pair best with gold cases, silver with silver or gunmetal cases, and dark bridges with black or steel cases. Does the NH71 need a skeleton dial? Yes. The gold-plated open-worked bridges are only visible through a skeleton dial — a dial with cutouts or transparent sections. Installing a solid dial over the NH71 would completely hide the gold bridge finish and waste the premium you paid over a standard NH38 or NH35. Always pair skeleton movements with skeleton dials. How accurate is the NH71 skeleton movement? The factory specification is ±20 seconds per day, identical to the NH70, NH72, and the solid NH35 family. The gold plating and open-worked bridges are cosmetic modifications to the base caliber and do not affect the timekeeping mechanism or accuracy.
