Description
Classic mid-century navigator sunglasses featuring a robust double-bridge design and signature green glass lenses. These frames represent a fusion of military utility and luxury craftsmanship, utilizing gold-filled metals for durability and luster.
Key Features
Square aviator frame, double-bridge brow bar, green mineral glass lenses, and heritage gold-filled construction.
Color & Finish
Silver-toned metallic finish with visible patina and oxidation. The surface shows a dull luster consistent with aged gold-filled eyewear.
Hallmarks & Stamps
Expected marks on the inner bridge or temple arms including '1/20 12K GF' or 'AO' (American Optical) / 'B&L' (Bausch & Lomb) signatures.
Dimensions Estimate
52-54mm lens width, 140mm temple length, standard men's navigator fit.
Gemstones & Inlays
Green mineral glass lenses (non-precious); acetate/plastic earpieces and nose pads.
Clasp & Closure
Standard screw-hinge temple joints; traditional wire-core paddle earpieces.
Chain & Links
Solid metal frame construction with a double-bridge (top bar) design for structural integrity.
Craftsmanship Details
Precision-stamped metal components with soldered bridge and hinge assemblies. High-quality mineral glass lenses with uniform tinting.
Authentication Indicators
The style of the screw hinges, the thickness of the frame rim, and the specific green tint of the lenses indicate period-correct manufacturing. Absence of modern laser-etching on lenses is consistent with age.
Origin & Maker
Likely USA; common manufacturers included American Optical, Bausch & Lomb, or Randolph Engineering.
Era & Period
Mid-Century / Retro (1960s-1970s). The squared-off aviator 'navigator' shape was a staple of military and civilian pilots during this era.
Age Estimate
Circa 1965-1975 based on the navigator lens shape and the yellowing of the acetate earpieces.
Cultural Significance
Symbolizes the 'Golden Age' of aviation and post-WWII American utility style; famously worn by figures in film and military history like Don Draper characters or real-life Apollo astronauts.
Condition Notes
Fair to Poor. Significant structural damage is visible: one lens is severely cracked. Metal shows oxidation and the plastic earpieces have yellowed significantly with age.
Value Estimate
$20-$50 in current damaged condition due to the cracked lens; if mint, these often retail for $150-$250 based on brand.
Care & Maintenance
Requires lens replacement by a professional optician. Metal frames should be cleaned with a soft microfiber cloth; avoid ultrasonic cleaners due to the cracked lens.
