Description
The Rado Starfire is a quintessential example of 1970s Swiss experimentalism. With its bold, architectural case and unique vertical day-date, it captures the 'Space Age' design language of the time. The dial is notable for shifting the traditional logo positions—placing the signature swinging anchor at 9 o'clock—creating a balanced, asymmetric aesthetic that is highly sought after by vintage Rado collectors.

Swinging anchor logo (indicating an automatic movement), Starfire flame emblem, vertical day-date complication, and integrated bracelet design.
Dial Description
Charcoal grey/slate matte dial with white printed minute track. Applied gold-tone faceted indices at 12, 6, and 9. Vertical day-date window at 3 o'clock. Features the swinging Rado anchor logo at 9 and the Starfire 'Flame' logo at 3.
Case Material
Stainless steel with a polished hooded lug finish and brushed flanks. Many models from this era also featured Rado's signature wolfram (tungsten carbide) scratch-resistant coating, though this appears to be the standard steel version.
Crystal Type
Raised boxed acrylic or mineral crystal. Slight edge distortion visible, typical of 1970s vintage crystals.
Bezel Details
Fixed, integrated into the monobloc style case. Polished finish with no markings.
Crown & Pushers
Recessed signed Rado crown at 3 o'clock. Push-pull operation for time setting and quick-set day/date function.

Water Resistance
Originally 30m (Splash resistant). Currently not recommended for any water contact due to age-related gasket degradation.
Origin & Provenance
Swiss Made. Manufactured in Lengnau, Switzerland. Uses an outsourced Swiss ETA base movement modified for Rado.
Age Estimate
Circa 1970–1975 based on the dial logo, T-Swiss Made-T tritium marking, and geometric case shape.
Cultural Significance
Rado was one of the first brands to move away from traditional round cases toward industrial, durable designs, helping define the 'funky' aesthetic of high-end Swiss watches in the 1970s.
Condition Notes
Very Good vintage condition. Minimal rounding of the case edges suggests light polishing. Crystal appears clear. Lume on hands and indices shows consistent age-related patination/darkening.
Value Estimate
$350 - $650 USD depending on bracelet tightness and movement health. Rare dial colors or 'New Old Stock' (NOS) condition can command higher prices.
Care & Maintenance
Water resistance should be assumed at zero for vintage pieces regardless of original rating. Service every 5-7 years to prevent movement wear and dry gaskets.

Interesting Facts
The 'Swinging Anchor' logo at 9 o'clock contains a tiny ruby jewel; it is not just for decoration—it is mounted on a pivot and rotates as the wearer moves, symbolizing the automatic rotor inside.
