Sevan - Skin diver 20 atm. Automatic - No reserve price - Men - 1960-1969

We are exceptionally proud to offer an investment-grade masterpiece of retro maritime horology: a massive, highly robust Sevan Automatic "Skin Diver" 17 Jewels gentleman's tool watch from the turn of the 1970s. This professional-grade timekeeper stands out with an incredibly rare 20 ATM factory-tested depth rating, an all-stainless steel monoblock-style case, and a pristine Swiss movement inside.

The Professional 20 Atmospheric Tool & Historical Context:
During the golden era of scuba diving exploration, specialized Swiss houses created "Skin Diver" watches engineered for extreme underwater duty. This premium specimen represents the absolute pinnacle of that era, explicitly stamped on its heavy caseback as "100% Waterproof Tested – 20 ATMOSPHERES". Offering an impressive 200-meter depth legacy, this watch far exceeds standard 5 or 10 ATM recreational dive watches of the period, making it a sensational addition to any high-end sports watch collection.

The Elite Swiss ETA 2522 Mechanical Engine:
Beneath the caseback ticks a masterclass in Swiss engineering: the high-grade Swiss Manufacture Caliber ETA 2522 with automatic winding. Stamped cleanly beneath the balance wheel along with the factory shield logo, this 10.5 Ligne movement features a classic silver-toned nickel/rhodium-plated factory finish with crisp graining. Equipped with an advanced bidirectional self-winding rotor and a premium Incabloc shock-absorption system, the mechanism is factory-clean and free of modern intervention.

The Tactical Matte Dial & All-Steel Oversized Presentation:
Unlike common mid-century sports watches manufactured from plated base metals that corrode, this watch boasts a heavy, solid stainless steel utility case measuring a prominent, highly modern 38 mm in diameter (excluding the crown) and an impressive 47 mm lug-to-lug. The unpolished housing features sharp contours, minor superficial hairline markings from careful historical wear, and a correct metal diver bezel that rotates smoothly in both directions.

The original matte deep charcoal/black dial is in a flawless state of preservation. It features high-visibility applied luminous markers displaying a vibrant, authentic green tritium-aged coloration. The layout is completed by clean silver baton hands and an aesthetically balanced date window framed at the 6 o'clock position, which advances regularly. The acrylic crystal is in absolute top condition, free of any scratches.

Technical Status & Documented Caseback:
The reverse is sealed via its original massive, polished stainless steel screw-down caseback, deeply engraved around the rim with All Stainless Steel, Antimagnetic surrounding the technical model reference 59289.
• Operational Status: The watch is in fully operational, excellent running condition. The automatic module works efficiently, it self-starts instantly upon the slightest crown movement, and ticks continuously with strong amplitude. The calendar mechanism engages correctly and flips the date wheel regularly.
• Timekeeping & Warranty Disclaimer: Due to the antique, 50+ year-old nature of this mechanical dive watch and its undocumented modern service history, standard periodic variances typical for historical calibers are to be expected. Sold strictly without modern service records, performance guarantees, or modern pressure testing certifications.
• Strap: Paired with a brand-new, unworn 18 mm high-quality smooth black leather strap equipped with a matching stainless steel buckle that perfectly mirrors the rugged utility aesthetic of the steel housing.

Please keep in mind that these historic mechanical wristwatches are described according to their condition verified during cataloging and are sold in their current authentic state without any documented service history. The watches are currently running and functional, however, no specific daily timekeeping accuracy, power reserve, or water resistance can be guaranteed due to the age of the movement, historical lubricants, wear on vintage parts, and external factors such as temperature/pressure changes, shocks, or changes in position during transport and wear. Timekeeping variations typical for vintage mechanical watches are to be expected and do not constitute a defect. This piece is sold primarily as a collectible and investment item. For daily use and to ensure optimal reliability, a professional service and adjustment by a watchmaker are highly recommended.
