WHAT IS THE DIFFERENCE BETWEEN THE NH35 AUTOMATIC MOVEMENT AND THE 4R35?
Simple answer? The branding on the oscillating weight (Rotor as some call it). Other than that, they are virtually identical.
“SII” stands for “Seiko Instruments Inc” and is in all technical purposes “Seiko” (Subsidary of Seiko Holdings Corporation).
The Seiko SII NH35 movement is the unbranded version of the Seiko 4R35 movement. Seikos NH35 Movement is known for being a work horse, and is the perfect movement to use in a build that will be passed down generation after generation. Most of Seiko’s older watches came with the very popular 7S26, which is the same base movement as the NH35 minus the hand winding, Hacking, and 3 jewel difference. The Date wheel, and the movement spacer on the 7S26 [black] and 4R35 (NH35) [gray] are fully interchangeable so don’t worry! This makes upgrading your old worn out 7S26 to a new NH35 very simple.
Hacking, handwinding, and the pure reliability of the NH35 will make this the perfect movement for your next modded Seiko, or even to build a watch from scratch! The SII NH35 movement will fit all the cases being sold on Watch-Modz. Our NH35 Movements pair well with our Lumed Day & Date Wheels which also fit 7S26!
Don’t hesitate any longer, Make sure you buy your NH35 Automatic Movement from the most reliable supplier on the market!
