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 community take
Owners talk.
Owners report the Undone Aquadeep Signal Automatic delivers solid build quality and reliability, with the NH35 movement earning consistent praise within the microbrand community for its dependable performance. The 43mm case and 500m water resistance appeal to those seeking a capable dive watch at accessible pricing. However, customer service and warranty handling have emerged as a significant pain point — one owner faced a falsely claimed delivery and order cancellation refusal, while another experienced water ingress that was not honored under warranty, contrasting sharply with owners who express genuine affection for the brand and maintain collections of its watches. Overall, the Aquadeep Signal Automatic is valued by its supporters for reliable timekeeping and finishing at the price, though prospective buyers should be aware of inconsistent post-sale support.
