Description

It features the highly sought-after 12-6-9 'Explorer' dial layout paired with a rugged dive bezel. Its design borrows heavily from high-end dive watches of the era but was intended for the recreational consumer market.

Matte black dial with 12-6-9 Arabic numeral layout (Explorer style); printed luminous baton indices; date window at 3 o'clock; Broad Arrow style hour hand and baton minute hand; printed 'T-SWISS MADE-T' for tritium use.
Case Material
Base metal (brass or nickel-plated) with integrated chrome plating; features brushed lug tops and polished sides with visible wear on the plating edges.
Crystal Type
High-domed acrylic/hesalite; shows significant surface scratching and minor crazing typical of aged plastic crystals.
Bezel Details
Bidirectional friction-fit bezel with black aluminum insert; 60-minute countdown/dive scale; significant fading/wear on the 0-20 segment and silvering at the edges.
Crown & Pushers
Unsigned oversized 'Big Crown' style; push-pull type (non-screw-down); generic knurling for grip.
Bracelet or Strap
Aftermarket flat-link stainless steel 'expansion-style' or H-link bracelet with straight end-links; brushed finish with significant gaps between links.
Caseback Details
Solid screw-down stainless steel caseback; typical engravings likely include 'Stainless Steel Back', 'Swiss Made', and 'Waterproof'.
Movement Type
Manual-wind or low-jewel automatic Swiss ebauche (likely EB, BF, or Ronda pin-lever movement); frequency estimated at 18,000 bph.
Water Resistance
Originally 5 ATM (50 meters) / 'Waterproof'; currently 0 ATM. Not suitable for even light splashes without a full pressure test and gasket replacement.
Origin & Provenance
Swiss Made; assembled in Switzerland using outsourced ebauche movements and generic cases (likely a Monnin or similar contract case).
Age Estimate
Circa 1968-1974; based on the transition from 'Waterproof' to 'Water Resistant' terminology and the tritium dial markings.
Cultural Significance
Represents the 'Skin Diving' craze of the 60s when SCUBA became a hobby; these watches were sold in department stores and sporting goods shops rather than just jewelry boutiques.
Condition Notes
Fair to Good; the case shows plating loss and brassing. The bezel insert is heavily worn. The dial and hands are remarkably well-preserved with a pleasing cream-colored lume patina. Crystal requires polishing.
Value Estimate
$150 - $350 USD depending on the specific movement grade and functional accuracy. Value is primarily in the 'vintage look' and dial condition.
Care & Maintenance
Avoid all water contact as vintage seals have likely failed. Service the movement every 5-7 years. Use PolyWatch to buff the acrylic crystal. Keep away from strong magnets.
