Description
A classic example of late-20th-century Swiss luxury sports design. This Longines Conquest features a utilitarian stainless steel construction elevated by a two-tone gold-plated finish on the bracelet center links and bezel. The piece balances durability with mid-tier luxury aesthetics.
Key Features
Distinctive 'Conquest' branding on the case back, winged hourglass logo, and the contrast between the dark steel plating and the gold-tone accents.
Color & Finish
Two-tone aesthetic featuring brushed and polished grey-black treated steel with high-polish yellow gold-colored center links. The case back shows a circular satin finish with significant scratching.
Hallmarks & Stamps
Stamped 'STAINLESS STEEL', 'Conquest', '21480680' (Serial Number), and the Longines winged hourglass logo along with the 'S' symbol often associated with Sapphire crystal or specific regional market stamps.
Dimensions Estimate
Case diameter approximately 33-35mm (Mid-size/Unisex); bracelet width approximately 18mm.
Gemstones & Inlays
None visible on the exterior; likely contains synthetic ruby jewels within the internal quartz or mechanical movement.
Clasp & Closure
Integrated folding deployment clasp, likely a hidden butterfly or single-fold style typical of 1990s Longines Conquest models.
Chain & Links
Three-row oyster-style link bracelet with integrated lugs. Center links are gold-toned while outer links are dark-treated steel.
Craftsmanship Details
Machine-stamped case back, PVD-coated steel bracelet links, and a Swiss-made quartz or automatic movement. Durable construction designed for daily wear.
Authentication Indicators
Alignment of the serial number and 'STAINLESS STEEL' stamp is consistent with Longines factory standards of the period. However, the heavy wear on the gold plating confirms this is not solid gold.
Origin & Maker
Switzerland; Longines (Compagnie des Montres Longines Francillon S.A.)
Era & Period
Late 20th Century / 1990s (Neo-Vintage)
Age Estimate
Circa 1990-1998, based on the font style of the 'Conquest' script and the serial number range.
Cultural Significance
Represents the 'Executive' watch style of the 1990s, where two-tone watches were considered the ultimate symbol of corporate success and versatility.
Condition Notes
Fair to Good. Visible heavy surface scratches on the case back and significant 'brassing' (wear-through of the gold plating) on the bracelet links, exposing the base metal underneath.
Value Estimate
$150 - $350 USD. The value is based on the brand name and horological utility; there is zero scrap gold melt value as the item is steel-based.
Care & Maintenance
Avoid abrasive polishing cloths which will further remove the thin gold plating. Clean with a soft damp cloth. Avoid immersion in water as gaskets may have perished with age.
