AI Appraisal Estimate

This is a vintage Unver De Luxe Seastar divers watch featuring a classic 'Super-Compressor' style stainless steel case with dual crowns at the 2 and 4 o'clock positions. The case is approximately 36mm to 38mm in diameter, excluding the crowns, which are used for setting the time and rotating the internal elapsed-time bezel. The matte black dial is marked with 'UNVER DE LUXE 25 Rubis' at the twelve o'clock position and 'Seastar AUTOMATIC INCABLOC' above the six o'clock position. It features bold, oversized luminous Arabic numerals at 12 and 6, and baton-style luminous hour markers for the other positions. A date aperture is visible at the 3 o'clock mark. The watch employs a three-hand movement with baton-style luminous hour and minute hands and a slim center seconds hand. The crystal appears to be domed acrylic, showing minor surface scratches and age-related wear. The dial shows a light, even patina on the lume plots, which have aged to a creamy yellow hue. The internal rotating bezel is black with silver markings and a luminous triangle at the zero position. The watch is currently paired with a black ladder-style rubber diving strap. This timepiece dates back to the 1960s, a golden era for professional dive watches, and showcases the robust craftsmanship associated with EPSA (Ervin Piquerez S.A.) case designs. Condition appears to be original and well-preserved for its age, with expected light scuffing on the polished steel surfaces.

I have virtually examined this Unver De Luxe Seastar Super-Compressor. This timepiece represents a classic example of the Ervin Piquerez S.A. (EPSA) dual-crown case design, highly coveted by vintage dive watch enthusiasts. Based on the provided imagery, the watch appears to be in an honest, well-preserved state. The 25-jewel automatic movement, the 'Super-Compressor' stampings (implied by the case silhouette/crowns), and the 1960s 'Seastar' branding are consistent with the era’s professional diving specifications. The market for 'Super-Compressors' remains robust. While Unver is a more obscure brand compared to Enicar or Longines, the shared EPSA case architecture and the charming aged patina on the Arabic numerals at 12 and 6 provide significant collector appeal. The dial’s original matte finish and the creamy yellowing of the tritium lume plots suggest authenticity and lack of invasive restoration. The presence of the internal rotating bezel and original-style cross-hatched crowns (if confirmed) significantly bolsters value. However, a remote visual inspection has limitations. I cannot verify the mechanical health of the 25-jewel movement, nor can I confirm if the case back carries the correct EPSA diver helmet logo. Full authentication would require a physical inspection of the movement for caliber identification and signs of water damage, a pressure test for gaskets, and an examination of the crown stems. Provenance or service records would further solidify this valuation. As presented, the piece is a desirable mid-tier vintage diver that balances rarity with the universal appeal of 1960s tool watch aesthetics.
