The Conquest reimagined
1. Longines Conquest Heritage Central Power Reserve.

Model launched to honour collection’s 70th anniversary

To mark the 70th anniversary of its emblematic Conquest collection, Longines is presenting its Conquest Heritage Central Power Reserve inspired by an iconic model from the late 1950s.

An evocation of daring and creative spirit, the Conquest collection was the first Longines watch line to have its name protected – in 1954 by the Swiss Federal Intellectual Property Office in Bern, Switzerland.

Self-winding and water-resistant, the Conquest line has always been associated with the world of sports and achievement.

Symbolising this spirit of conquest, the collection was expanded in 1959 to include a model with a one-of-a-kind power reserve indicator, consisting of two rotating discs located in the centre of the dial.

To mark the 70th anniversary of the Conquest collection (1954-2024), Longines is reimagining this classic with the new Conquest Heritage Central Power Reserve.

The striking tribute feature, invented by Longines and used exclusively by the brand, places the power reserve indicator on the central uncoiling disc.

2. The double discs spin to indicate the power reserve.

In the shape of a baton widened at the top, it indicates the movement’s depletion level on the external coiling disc, graduated from ‘64’ to ‘0’.

It reveals the balance of power-reserve hours available, or in other words, the watch’s remaining running time.

(The power reserve is a measure of how long this stored energy, produced by winding a spring, will enable the mechanical watch to tell the time without rewinding.)

Rewinding can be done either by turning the crown or moving the wrist, causing the coiling disc to rotate.

The aesthetics of the dial thus change continuously, creating an original poetic effect of the passage of time.

3. L896.5 calibre powers the watch.

This innovative mechanism echoes the long history of Longines watches with rotating discs, such as the hour-angle models developed for the aeronautical industry in the late 1920s.

Available in champagne, anthracite or black, the three-part dial of the Conquest Heritage Central Power Reserve is edged on its fixed part by 12 yellow gold-coloured, rose gold-coloured or silver-coloured applied facetted hour markers.

In keeping with the characteristic circles motif of the Conquest collection, a fine circular thread carries the facetted hour markers and separates the minute track on the fixed dial.

Another feature of this model is that the date is displayed at 12 o’clock in a date window decorated with a trapezoid-shaped applique.

Like the hour markers which colours they adopt, the unusual skyscraper-style hour and minute hands are coated with SuperLumiNova.

Demonstrating the watchmaking expertise and timeless elegance of the winged hourglass brand, the Conquest Heritage Central Power Reserve is powered by the new exclusive Longines L896.5 calibre, visible via the transparent screw-down case back.

4. The many components that make up the watch.

Equipped with a silicon balance-spring and innovative components, this self-winding mechanical movement offers a magnetic resistance up to 10 times greater than the ISO764 benchmark standard.

The completely redesigned 38mm steel case, with alternating satin-finished and polished surfaces, is topped by a box sapphire crystal with multi-layer anti-reflective treatment on both sides.

The lugs have also been redesigned for optimum ergonomics and comfort.

The Conquest Heritage Central Power Reserve is available with black or grey leather straps, fitted with a new steel pin buckle, in common with the latest models in the Conquest Heritage line.

Backed by centuries of watchmaking expertise, Longines equips all its automatic timepieces with cutting-edge movements which features include a silicon balance-spring.

Silicon is not only lightweight and corrosion-resistant, but also unaffected by normal temperature fluctuations and magnetic fields.

Its unique properties boost the watch’s precision and longevity and allow Longines to guarantee these models for five years.
