Seiko's third-party supply version of the 4R35, sold to external watch brands and modders worldwide. Adds hacking and hand-winding over the 7S26 it effectively replaced. The NH35 has become the default automatic movement for watch modding and microbrand watches, thanks to its low cost, reliability, and wide availability of compatible parts including dials, hands, and cases in the Seiko-compatible format.

The community take
Owners widely praise the Addiesdive Automatic Diving Watch Diver's 200M (H3AC) for its excellent value, robust Seiko NH35 movement, and 41mm case size that fits well on average wrists. The case finishing is noted as good for the price, featuring a brushed and polished combination. However, some owners question the actual diving water resistance and warranty reliability, while one owner reported poor power reserve and a stiff screw-down crown. The seconds hand is criticized by some as looking cheap, and the bezel action is described as rotating too easily with a hollow sound. On balance, owners rate the Addiesdive Automatic Diving Watch Diver's 200M (H3AC) highly for its impressive value and reliable movement at its price point.
