Longines Flagship Ref. 4027-4 - Natural Patina, Endless Elegance!
The true magic lies in a watch's ability to live time, rather than simply measure it.
This Longines Flagship is the definition of both naturalness and elegance. The magnificent patina on its dial has created a beauty that cannot be willed by human effort, but only time can bestow. Furthermore, the case looks "new," as if it hasn't been worn for years—almost New Old Stock (NOS).
IMPORTANT NOTE: Since this product will be shipped within the European Union, you will not pay customs duties if you are within the EU.
This combination gives it a unique, unparalleled appearance.

This caliber represents the purest form of the "thin yet powerful" mechanical architecture developed by Longines in the late 1960s and early 1970s.
Its design is notable for its minimal bridge structure and wide balance ring.
It is precise, quiet, durable, and capable of years of trouble-free operation.
Design and Dial
What makes this Flagship model special is its natural dial patina.
This watch likely sat unused in a dark drawer or box for many years.
The result: a unique surface tone created by the subtle effects of sunlight, weather, and time.
The wood grain texture on that blue background almost looks like "frozen time."
This kind of patina cannot be reproduced with paint, chemicals, or craftsmanship. This dial, which reflects light differently from every angle, creates a sense of depth that lives on, like brushstrokes in a painting.
Therefore, the owner of this watch will not only own a Longines watch, but also a unique work of art painted by the hands of time.
Case and Form
The case perfectly reflects the elegant refinement of Longines from that era.
Its brushed surfaces and polished bezel line diffuse light exceptionally.
Its slender profile makes it both comfortable and aesthetically pleasing.
The embossed Longines logo on the crown is an elegant yet characteristic touch.
This watch is one of the most refined examples of the "neoclassical minimalism" movement of the 1970s.

The Story of the Flagship Series
Introduced in 1957, the Longines Flagship series is one of the brand's most established mechanical lineages.
Flagship means "flagship" - and this name perfectly defines the collection's place in the brand's heritage.
During the 1960s and 1970s, the Flagship became the face of Longines, with its classic design, elegance, and durability.
The reference 4027-4 is one of the thinnest and simplest hand-wound variants in this series.
With its minimalist dial and slender case, it is considered the "quiet face of Swiss elegance."
