====== Seiko NH Series ====== The **NH Series** from [[Seiko]] is a line of movements derived from the Seiko 4R.. calibers. Both are manufactured by Time Module (TMI). The key difference lies in their intended use and features: The 4R.. caliber is Seiko’s proprietary caliber for its own watches, while the NH.. calibers are licensed to third-party manufacturers. The NH Series (e.g., NH35, NH36, NH38, NH71) is considered a robust and reliable workhorse that forms the foundation of the modern micro-brand trend. * NH34 -> [[Seiko 4R34]] * NH35 -> [[Seiko 4R35]] * NH36 -> [[Seiko 4R36]] * NH38 -> [[Seiko 4R38]] * NH71 -> [[Seiko 4R71]] {{tag>Movement_manufacturers Movement_manufacturers_Japan Seiko}}
