Type
Watch (Luxury Dress/Avant-Garde)
Purity
PVD Coated / Gold-Plated (Non-solid gold). This item is made of hardmetal (tungsten carbide) with a Physical Vapor Deposition (PVD) gold-colored coating rather than solid gold.
Gold Type
Yellow gold-tone PVD coating. The alloy is a simulation of high-carat yellow gold, designed for extreme durability and scratch resistance.
Weight
120 - 150 grams. Due to the high density of the tungsten carbide hardmetal case, this item is significantly heavier than a standard steel watch, though it contains negligible precious metal weight.
Description
A stunning Rado DiaStar featuring the world-renowned oval scratch-proof hardmetal bezel. This piece showcases a striking black dial with a gold geometric starburst pattern, accented by vertical day-date display at 6 o'clock. Its architectural presence and permanent luster make it a staple for collectors of avant-garde horology.
Key Features
Tungsten carbide bezel (virtually scratch-proof), vertical Day-Date complication, rotating Rado anchor logo at 12 o'clock, and unique 'Spider' geometric dial motif.
Color & Finish
Mirror-polished deep yellow gold. The iconic DiaStar finish is a high-gloss, ultra-reflective surface that is virtually impervious to scratches due to the hardness of the base material.
Hallmarks & Stamps
Rado Logo (Rotating Anchor), 'DiaStar' on dial, 'Swiss Made' at 6 o'clock, serial numbers and 'Tungsten Carbide' or 'Water Sealed' typically engraved on the stainless steel case back.
Dimensions Estimate
Approximately 35mm x 42mm case diameter; 12mm thickness. Retro-oval lugless case design fitting standard men's or unisex medium wrist sizes.
Gemstones & Inlays
Synthesized diamond or crystal hour markers. These are typically simulated stones (CZ or high-grade crystals) set in square faceted mounts against a black geometric line-art dial.
Clasp & Closure
Gold-tone stainless steel folding clasp with a sliding adjustment or tiered link system. Features Rado branding on the outer fold.
Chain & Links
Three-row 'NSA' style or brick-link bracelet. The links are flexible, gold-plated stainless steel, designed for comfort and a vintage aesthetic.
Craftsmanship Details
Precision-engineered hardmetal casting and diamond-wheel polishing. Swiss automatic movement (likely ETA 2836-2). Dial features high-quality pad printing and applied faceted indices.
Authentication Indicators
The rotating anchor logo (which should move freely with gravity), the specific mirror-like reflection of hardmetal which differs from the softer glow of solid gold, and the vertical alignment of the day-date wheel.
Origin & Maker
Switzerland; Rado (a division of the Swatch Group). Known as the 'Master of Materials' for pioneering the use of scratch-proof metals.
Era & Period
Modern production inspired by the 1962 original. The geometric 'spider' dial pattern and oval case are classic 1970s Retro-Futurism indicators.
Age Estimate
Likely produced within the last 10-20 years (circa 2000-2020), based on the specific dial pattern and modern date/day complication layout.
Cultural Significance
A cultural icon in South Asia and the Middle East, the DiaStar is often gifted for weddings and major milestones as a symbol of 'everlasting' beauty and success due to its inability to scratch or age.
Condition Notes
Very Good. The hardmetal bezel appears immaculate (as expected). Minor signs of wear may be present on the bracelet links or clasp which are made of softer steel. Grade: Excellent (Case) / Very Good (Bracelet).
Value Estimate
Market value: $450 - $900 USD depending on movement type (Quartz vs Automatic). Note: This item has zero 'melt value' as it is a base metal alloy with a microscopic gold layer.
Care & Maintenance
Wipe with a soft cloth. The bezel needs no polishing. Avoid dropping on tile surfaces, as hardmetal can be brittle and shatter despite being scratch-proof. Mechanical service recommended every 5 years.

Interesting Facts
When introduced in 1962, the Rado DiaStar was the world's first scratch-proof watch. The rotating anchor logo on the dial is actually a functional indicator; it is mounted on a jewel and its movement indicates the automatic movement is functional.
