Why It Stands Out
The Conquest Heritage Central Power Reserve occupies a specific and credible position in the mid-range Swiss market. It carries a genuine technical provenance, one rooted in a 1959 Longines reference that was the first to place a power reserve display at the centre of the dial on rotating discs. That is not a styling decision; it is a documented piece of Longines engineering history.
For GCC collectors who value traceability in a watch’s story, this matters. The 2026 edition does not reinvent; it extends a line established for the Conquest collection’s 70th anniversary in 2024, adding a light blue opaline dial that reads as contemporary without abandoning the vintage architecture underneath.
Heritage & Lineage
The Conquest collection launched in 1954, Ref. 9001, and was the first Longines line to have its name protected by Switzerland’s Federal Intellectual Property Office in Bern. The 1959 Conquest Automatic, Ref. 9028, introduced the central rotating-disc power reserve, a display that Longines invented and has used exclusively ever since.
The current Central Power Reserve traces a direct line through the 2014 60th-anniversary re-issue (Ref. L1.611.6.70.4) and the 2024 70th-anniversary edition (Ref. L1.648.4.78.2) before arriving at the 2026 variant. The continuity across those references is deliberate and legible to anyone who follows the collection. Ahead of events such as Watches and Wonders, that kind of consistent evolutionary narrative is precisely what distinguishes a collection from a one-off release.
Movement & Materials
The calibre L896.5 is a self-winding movement running at 25,200 vph across 21 jewels. Its silicon balance-spring makes it resistant to magnetic fields under ISO 764, and Longines backs it with a five-year guarantee. Autonomy reaches 72 hours, giving practical buffer for weekend removal.
The 38 mm case is finished in alternating satin-brushed and polished surfaces. A box sapphire crystal with multi-layer anti-reflective coating on both sides keeps glare away from the light blue dial, which is populated by 12 applied, facetted rhodium-plated indexes and skyscraper-style hands filled with Super-LumiNova. The trapezoid-framed date aperture at 12 o’clock is a period-correct detail that ties the dial’s geometry together.
Design & Mechanics
The central power reserve is the dial’s organising principle. The outer disc, graduated from 64 to 0 hours, rotates continuously as the mainspring unwinds. A baton-shaped indicator marks the remaining energy, its movement visible in real time. The Fondation Haute Horlogerie has long cited the power reserve as one of the complications that bridges legibility and craft, and Longines’ rotating-disc interpretation delivers exactly that: information presented visually, not just numerically.
The two strap configurations serve different expressions of the same watch. The stainless-steel bracelet, fitted with a double-folding safety clasp, a push-piece opening, and an integrated micro-adjustment system, reads as a sports-dress piece suited to Gulf business and social settings. The grey alligator strap with heritage pin-buckle shifts the register towards vintage dress, amplifying the 1959 reference point.
Market Position
Within the Swatch Group portfolio, Longines occupies the accessible luxury segment. The Conquest Heritage Central Power Reserve competes on the strength of its technical specificity: a complication with a documented in-house origin, housed in a case size (38 mm) that suits a broad range of wrist profiles prevalent across the GCC market.
The light blue dial broadens the palette deliberately. It positions the 2026 release as a distinct purchase alongside the existing editions rather than a replacement, which keeps resale logic intact for existing holders. For the collector building a focused Longines sub-collection, references L1.648.4.92.6 (bracelet) and L1.648.4.92.2 (strap) each occupy a clear and non-overlapping role.

Frequently Asked Questions
What movement powers the Longines Conquest Heritage Central Power Reserve?
The watch is powered by the exclusive Longines calibre L896.5, a self-winding mechanical movement with a silicon balance-spring. It operates at 25,200 vibrations per hour, offers a power reserve of up to 72 hours, and carries ISO 764 magnetic-field resistance.
What case size does the 2026 Conquest Heritage Central Power Reserve use?
The case measures 38 mm in diameter and 12.30 mm in thickness, crafted in stainless steel with alternating satin-brushed and polished finishes. Lug-to-lug distance is 45.60 mm, with a lug width of 19 mm.
How does the central power reserve display work on the Conquest Heritage?
The function uses two rotating discs positioned at the centre of the dial. A baton-shaped indicator moves across an outer disc graduated from 64 to 0 hours, giving a continuous, intuitive reading of remaining power reserve. The mechanism was first used by Longines on a 1959 Conquest reference.
What strap and bracelet options are available for the 2026 edition?
The watch is offered in two variations: one with a stainless-steel bracelet featuring a double-folding safety clasp with micro-adjustment, and one with a grey alligator strap secured by a heritage pin-buckle. Both share the same light blue opaline dial.
What is the water resistance of the Longines Conquest Heritage Central Power Reserve?
The watch offers water resistance up to 5 bar, equivalent to 50 metres, making it suitable for everyday wear and incidental water exposure.
