Description
The Rado DiaStar is one of the most polarizing and recognizable designs in horology. Launched in 1962 as the world's first scratch-proof watch, it utilizes tungsten carbide to ensure the watch looks new decades after purchase. This specific model features the iconic champagne dial with a vertical day-date, a hallmark of the DiaStar's 'Space Age' design language. Its metallic lustre and faceted crystal give it a distinct architectural presence on the wrist.
Key Features
Scratch-proof Hardmetal case, faceted sapphire crystal, swinging anchor logo (which rotates based on the watch's orientation), and the unique vertical 6 o'clock day-date display.
Dial Description
Champagne/Gold-tone dial with a vertical Day-Date window at 6 o'clock. Features 11 applied crystal or cubic zirconia hour markers (omitting 6), gold-tone baton hands, and a swinging anchor logo at 12 o'clock.
Case Material
Hardmetal (Tungsten Carbide) scratch-proof bezel/top case with a stainless steel inner chassis. The case exhibits a mirror-polished, faceted finish that is highly scratch-resistant.
Crystal Type
Faceted Sapphire Crystal. The crystal features longitudinal facets that create a unique play of light, reflecting the geometric lines of the case.
Bezel Details
Integrated Hardmetal bezel, fixed, sloped oval design, mirror-polished. It is designed to be 'scratch-proof' and virtually indestructible under normal wear.
Crown & Pushers
Small, recessed push-pull crown at 3 o'clock, often signed with the Rado anchor logo; designed to maintain the sleek aerodynamic profile of the oval case.
Bracelet or Strap
Two-tone (Silver/Gold) Novavit-style or link bracelet, stainless steel with PVD gold plating on the center links. Features a folding clasp with a spring-loaded comfort extension.
Caseback Details
Solid stainless steel screw-down caseback, typically featuring the Rado 'Seahorses' or 'Water-Sealed' engraving and the reference/serial numbers.
Movement Type
Automatic, ETA 2836-2 or similar, 25-28 jewels, 28,800 bph, approximately 38-40 hour power reserve, featuring a day-date complication with vertical alignment.
Water Resistance
Typically rated for 30m (3 ATM). It is splash-resistant but not recommended for swimming or diving, especially as gaskets age.
Origin & Provenance
Swiss Made. Produced in Lengnau, Switzerland. The movement is a Swiss ETA, typically modified or regulated for Rado.
Age Estimate
Modern production, likely 2010s to present. The 'The Original' series maintains the 1962 DNA but uses modern sapphire and updated ETA movements.
Cultural Significance
A massive cult classic, particularly in South Asia, the Middle East, and among retro-futurist design enthusiasts. It represents a shift in the 1960s toward using industrial materials in luxury watchmaking.
Condition Notes
Visual condition appears 'Good' to 'Very Good.' The Hardmetal case appears free of scratches (as expected), though the gold PVD plating on the bracelet links shows minor signs of potential wear. The crystal facets appear sharp. Overall Grade: 8.5/10.
Value Estimate
$500 - $900 (Secondary Market); MSRP for modern versions typically ranges from $1,200 - $1,500 depending on diamond/crystal accents.
Care & Maintenance
Recommended service every 5–7 years. While the case is scratch-proof, it is brittle; a hard impact on a stone floor can shatter the tungsten carbide. Avoid dropping. Clean with a soft cloth to maintain the mirror finish.

Interesting Facts
The DiaStar was the first watch to use tungsten carbide and sapphire crystal together. The 'swinging' anchor on the dial is not just a logo; it is mounted on a jewel and rotates to indicate that the watch has a mechanical movement rather than quartz.
