Integrated smooth fixed bezel, part of the monobloc/monocoque hardmetal case construction. Polished finish with rounded edges.
Crown & Pushers
Small, gold-plated push-pull crown with knurled edge for grip. Non-screw down, keeping with the slim dress watch aesthetic.

Black Milanese/mesh PVD stainless steel strap. While the watch head is gold-toned, it is pictured here on a contrast-heavy aftermarket or optional black mesh strap with a sliding adjustable buckle.
Caseback Details
Solid stainless steel snap-on case back. Typically features the Rado 'Seahorse' emblem, the 8-digit reference number, and 'Water Sealed' text.

Origin & Provenance
Swiss Made. Hand-assembled in Lengnau, Switzerland. Uses an in-house adjusted Swiss ETA quartz movement.
Age Estimate
Circa 1985-1995. The 'DiaStar' branding without the rotating anchor logo (common on automatics) and the specific 6 o'clock date placement are indicative of this era.
Cultural Significance
Rado became a massive cultural icon in Asian and Middle Eastern markets during this period due to the prestige of gold-colored watches that never scratched or faded, symbolizing lasting success.
Condition Notes
Good condition. The case appears remarkably scratch-free (a benefit of hardmetal), though the gold PVD on the crown shows slight wear. The dial is clean. The mesh strap is a later replacement and not original to the gold-toned head. Grade: Very Good.
Value Estimate
Secondary market value: $250 - $450 USD. Value is increased by the presence of the original gold-plated Rado bracelet and original box/papers.
Care & Maintenance
Battery changes every 2-3 years. Check gaskets annually to maintain water resistance. Avoid dropping on hard surfaces like tile, as hardmetal and sapphire are brittle and can shatter even though they don't scratch.
Similar Watches
Longines La Grande Classique, Movado Museum Watch, Omega De Ville Quartz. The Rado stands out due to its much harder case material compared to the more fragile gold plating of its competitors.
Interesting Facts
Rado released the first 'scratch-proof' watch in 1962. The DiaStar line was revolutionary because it stayed looking new for decades, whereas contemporary gold or steel watches would show immediate scratches.
