Water Resistance
Originally rated for 3-5 ATM (30-50m), but should be considered 'not water resistant' today due to age and gasket perishability.
Origin & Provenance
French assembly with Swiss-made movement parts. France (likely Morteau or Besançon region) manufacturer.
Age Estimate
Circa 1970–1975 based on the case shape, dial typeface, and '25 Rubis' (Jewels) designation.
Cultural Significance
Represents the 'Space Age' design movement in horology where traditional round dress watches were replaced by bold, geometric, and experimental steel shapes.
Condition Notes
Good vintage condition. The case shows honest wear with softening of the brushed edges. The acrylic crystal has light scratching. Dial and hands appear well-preserved without significant oxidation. Grade: Very Good (Vintage).
Value Estimate
Market value: $150–$350 USD. Value is driven by the aesthetic appeal of the blue dial and the stainless steel case rather than brand prestige.
Care & Maintenance
Mechanical service recommended every 5-7 years. Avoid water as vintage seals are likely degraded. Keep away from strong magnets. Clean bracelet with a soft dry cloth.

Interesting Facts
ARP was one of many smaller European brands that vanished during the 'Quartz Crisis' of the late 70s. These brands often used the same high-quality Swiss internals as more famous houses but at a fraction of the cost.
