1960s Shanghai 555 15-Day Mechanical Wall Clock

• Original vintage Shanghai 555 mechanical wall clock, featuring a 15-day movement for less frequent winding. • Constructed with a wooden glazed case, typical of mid-century clock designs. • Fully functional: keeps accurate time, winds normally, and chimes on the hour and half-hour. • Includes original pendulum and winding key for complete operation. • Shows age-related wear consistent with 57 years of ownership, with no cosmetic restoration. • A rare surviving example of a 1960s Chinese mechanical clock with documented Nigerian provenance.
