Nodus
Nodus is an American watch brand and development company in Los Angeles, established in 2017. It states that watches are assembled, regulated and tested in its local workshop, with an international supply chain. US assembly therefore does not mean that every component was manufactured in America.
Its development work includes the Nodus Extension Module, or NEM, a quick-adjustment mechanism for bracelet clasps. The maker describes pressing down with one hand while the other slides the bracelet in or out. NEM identifies a clasp mechanism, rather than a watch movement.
Establish the model and version before describing a used watch's movement, materials and functions. A particular clasp or technology should not be assumed across every Nodus watch. Record whether the bracelet is original or a later replacement.
