Seiko NH35 Modified Movement Moon Phase

We take the legendary Seiko NH35 movement—renowned worldwide for its reliability—and elevate it with thoughtful custom modifications. First, we integrate a sophisticated calendar and moon phase complication at the 6 o’clock position. As a result, this addition brings both practical utility and poetic charm to your watch. The moon phase window gracefully tracks lunar cycles, while the date display keeps everyday life in perfect sync.

We equip this modified NH35 with four dedicated hands. Therefore, you enjoy precise separation of hours, minutes, seconds, and complication functions. For instance, the central hands handle standard timekeeping, while the dedicated sub-dial hand indicates the moon phase progression. Consequently, reading the dial becomes intuitive and effortless, even at a glance.

The NH35 shines through its clean, understated aesthetic. We preserve its signature simplicity—crisp bridges, balanced layout, and uncluttered finishing.It features 24 jewels, a 41-hour power reserve, and hacking seconds for precise setting. Moreover, its robust construction withstands daily wear with proven Japanese reliability.

We specialize in tailoring the NH35 to your exact preferences. You can add calendar and moon phase functions, choose custom rotor engraving, select finishing styles, or incorporate other complications. Our in-house experts work closely with you throughout the process. As a result, your modified Seiko NH35 becomes a truly personal masterpiece—blending legendary reliability with bespoke sophistication.
