SEIKO Presage SSA447 Special Features
CONCEPT
Seiko Presage welcomes a new series that captures the vintage feel of a Seiko milestone watch combined with the traditional watchmaking skills for which the Presage collection is renowned.
The new Seiko Presage “Style60’s” series design takes its inspiration from the Crown Chronograph introduced in 1964. With contemporary earth tone colors, the watches combine the vintage design of the 1964 creation with contemporary elements to create a series with a retro feel perfect for modern times.
The Crown Chronograph was Seiko’s and Japan’s first wristwatch equipped with a stopwatch function.
The watch had several new revolutionary functions
and marked the beginning of Seiko’s chronograph wristwatch manufacturing.
Style
The new series incorporates the Crown Chronograph’s characteristic box-shaped glass, faceted indexes, and sharp hand designs. The inner circular area of the dial and the outer area with indexes are applied different finishing techniques, creating enhanced legibility, and a warm vintage feel with varying expressions depending on the angle of view.
Case design
The gently rounded case is slightly slanted inward to ensure comfort on the wrist.
The lugs are carefully polished to a mirror finish giving the watches a sharpness to their overall calm and gentle appearance, creating the perfect balance of modern and vintage.
While the original Crown Chronograph did not incorporate a date window, the series offers new creations with a calendar function.
SEIKO Presage SSA447 History
Presage. The product of a century and more of experience
In 1913, Seiko made its first mechanical watch. 1956, Seiko made its first automatic watch. 1958 Seiko created its shock resistant system, Diashock, to preserve precision when the movement is subject to impact. 1959, Seiko invented the Magic Lever spring winding mechanism, and in 1964, it started producing balance springs in-house, utilizing its own specially developed alloy, Spron. 1967, Seiko created Japan’s first hi-beat caliber. 1969, Seiko made the world’s first automatic chronograph with vertical clutch and column wheel systems and in 2014 Seiko’s mechanical watchmaking skills were rewarded with a prize at the Grand Prix d’Horlogerie de Genève for its hi-beat caliber.
For over a century, Seiko has developed and refined its mechanical watchmaking skills. Today, all this experience comes together in a new, all-mechanical, collection named Presage. Presage has already been successful in Japan and selected other markets for some time. Now Presage goes global and takes center stage as Seiko’s leading mechanical watch collection.
Presage: A wide range of calibers, designs and tastes
Presage is a collection of broad appeal. It comprises 60 models and uses the full range of Seiko’s mechanical calibers, from the accessible 4R, through 6R to the exclusive 8R. Highlights include the 6R27 multi-hand power reserve model and a series using an entirely new version of the 4R57 caliber. This new caliber is Seiko’s first ever with a center power reserve indicator, and is available in a series of five designs, including a limited edition. Every Presage watch has 10 bar water resistance and a sapphire crystal.
Japan is a land with a long and unbroken cultural history and therefore values tradition very highly. Long-lasting beauty and long-lasting performance express the deep desires of Japanese culture and are therefore at the heart of Japanese craftsmanship. Both in design and manufacturing values, Presage belongs firmly in this tradition and offers the very highest levels of reliability and durability over time. Each Presage watch is built to last for generations.
