The Longines Conquest Heritage Central Power Reserve line masterfully honors the rich historical legacy of the Swiss brand. The two models are L1.648.4.92.2 and L1.648.4.92.6, they perfectly blend classic 1950s styling with modern watchmaking technology.
Specification

The durable stainless steel case houses this unique mechanical design. The case measures 38mm in diameter, lug-to-lug distance is 45.6mm, and it has a thickness of 12.3mm.
Alternating satin-brushed and polished surfaces decorate the sleek metal exterior. This careful finishing technique enhances the elegant silhouette of the watch.

The case features a classic polished bezel. A prominent crown rests on the side of the watch. This crown proudly bears the relief-engraved winged hourglass emblem.
A screw-down transparent case back secures the inner mechanism. This window allows watch enthusiasts to view the beautiful automatic movement inside. The entire structure offers reliable water resistance up to 50 meters.
A highly durable box-shaped sapphire crystal protects this intricate dial arrangement. The glass features multi-layered anti-reflective coating on both sides for superior clarity.
Dial

A gorgeous light blue opaline dial serves as the face of these new models. This specific color choice offers a refreshing and contemporary appearance.
The opaline texture provides a smooth and slightly matte finish under bright lighting. This delicate finish highlights the sophisticated sector layout of the dial.
Rhodium-plated skyscraper hands smoothly indicate the hours and minutes. Longines fills these hands with bright Swiss Super-LumiNova for nighttime reading.

Twelve applied faceted rhodium-plated indexes mark the hours around the edge. A unique trapezoidal date window sits prominently at 12 o’clock.
At the very center lies the main attraction of the entire timepiece. Two rotating discs work together to display the power reserve.
A slender baton indicator on the inner disc points to an outer scale. This scale tracks the stored energy from 0 to 64 hours. Watch owners can watch the discs move dynamically throughout the day.
Movement

The exclusive Longines Caliber L896.5 powers the advanced wrist watch. This self-winding mechanical movement beats at a frequency of 25,200 vibrations per hour.
The advanced caliber contains 21 jewels to minimize mechanical friction. It utilizes a monocrystalline silicon balance spring to improve timekeeping precision.
This advanced material provides excellent resistance against disruptive magnetic fields. The mechanism stores an impressive power reserve of up to 72 hours. This 3-day power capacity easily outlasts the 64 hour scale on the dial.
The remaining eight hours act as a performance buffer for optimal torque. Fine horological decorations like perlage and Geneva stripes embellish the movement components.
