Description
An elegant example of Swiss precision and avant-garde metallurgy, this Longines Conquest combines the lightweight strength of aeronautical-grade titanium with the luxury of 18K yellow gold.

Two-tone finish: Matte charcoal-grey titanium contrasted with high-polish yellow gold middle links and bezel accents. The dial features a sunburst grey-to-black finish.
Hallmarks & Stamps
Longines logo and 'Quartz' on dial; likely 'Titanium 750' or 'Titanium/Gold' stamped on the case back or the fold-over clasp. Swiss Made marking at 6 o'clock position.

Three-piece horizontal link construction; outer links in matte titanium, center links in polished 18K yellow gold. Pins are internal and friction-set.
Craftsmanship Details
Precision Swiss assembly; high-tolerance fit between dissimilar metals (titanium and gold); vacuum-sealed case construction for water resistance (usually 3 ATM).
Authentication Indicators
Alignment of the Longines winged hourglass logo; crispness of the 'Quartz' serif font; quality of the link articulation; matte texture consistent with sandblasted titanium rather than painted steel.
Origin & Maker
Switzerland; Longines (Compagnie des Montres Longines Francillon S.A.).
Era & Period
Late 1980s to early 1990s (Neo-Vintage). Reflects the 'Bold Gold' transition into tech-forward materials like titanium.
Age Estimate
Circa 1988-1995. This specific 'Conquest' design language was a hallmark of Longines' high-end quartz catalog during this period.
Cultural Significance
Represents the 'Executive' style of the 1990s where thin, quartz-powered luxury watches were preferred over bulky mechanical pieces as a symbol of modernity and efficiency.
Condition Notes
Very Good. The titanium shows typical light scuffing (typical for the material). Gold links appear well-preserved without significant thinning. Dial and hands show no signs of oxidation.
Value Estimate
$400 - $700 USD. Value is based primarily onブランド (brand) and collectible appeal rather than melt value, as the gold weight is decorative.
Care & Maintenance
Avoid ultrasonic cleaners as they can loosen links; clean with a soft toothbrush and warm soapy water; requires battery replacement every 2-3 years; titanium can be professionally re-blasted if heavily scratched.
