Seiko
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 Unimatic Modello Quattro UC4 Classic Time Only features a robust 40mm black DLC case, 13.7mm to 13.9mm thick, with drilled lugs and a fixed steel bezel that balances beefiness with wearability. Reviewers note improved crown action and refinement over earlier models, with a flat sapphire crystal. Its sandwich dial reveals Super-LumiNova BG W9 beneath cut-out indexes, paired with a Seiko NH35A automatic movement. While the movement is considered robust and reliable, one reviewer expressed a preference for a Sellita caliber given the watch's heft. On balance, reviewers find the Unimatic Modello Quattro UC4 Classic Time Only to be a well-refined and wearable tool watch with a distinct military character.
