Urgos Helical Hairspring Balance Unit – Rare NOS (New Old Stock)
This is an original Urgos helical hairspring balance unit, a rare and hard-to-find component for high-quality clock restorations. Urgos, a renowned German clock movement manufacturer, ceased operations in the late 1990s, making these original floating balance units even more valuable. With no more in production, remaining new old stock (NOS) units like this one are highly sought after by collectors and clockmakers.
