Some candy for the eyes: Longines 13 ZN Cream Dial, Mushrooms pushers.
The train has long gone with this reference. Years have passed, and it is now almost impossible to find and fund one as nice as this 13 ZN:
Everything is magic here. From the patina of the dial, the dial itself, the step bezel, the pushers.
A good example of how a vintage Longines can be magic.
