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 praise the Undone Party2gether for its 40mm size, 316L stainless steel case, and reliable NH35 movement. However, the watch is criticized for its Lexan polycarbonate crystal, which is seen as a downgrade from sapphire, and the standard black PVD coating is noted as potentially scratching easily. On balance, owners consider the Undone Party2gether a respectable collaboration for its price point, with the main drawbacks being the crystal material and PVD durability.
