1959 · Calibre Longines 291 · Ref. 9001-5
Longines’ in-house automatic, from the era when the manufacture outsourced nothing. The enamelled medallion on the case back is intact — an increasingly rare thing.

A unique piece — available at the workshop
A 1959 Conquest, calibre 291, the automatic movement Longines still built entirely in-house. I disassembled everything, replaced the hairspring and the rotor bearings, then regulated it in five positions: ±7 seconds a day.
The enamelled medallion on the case back is intact, which is becoming rare on these Conquests. The steel case was repolished by hand, respecting the curved flanks. New crystal, original untouched dial, new gold-tone leather strap.
