Dimensions
Standard men's mid-century size; approximately 34-36mm diameter excluding crown; weight approximately 30-45 grams including case and non-precious metals.
Description

Material & Composition
Stainless Steel back; base metal (likely chrome-plated brass) for the main case body. Note: This item contains no silver content.
Finish & Decoration
Machine-polished stainless steel back with circular brushing; stamped central logo featuring a diver/skier figure; chrome-plated lugs and mid-case with significant pitting and wear.
Hallmarks & Stamps
Stamped: 'STAINLESS STEEL BACK', '100% WATERPROOF', 'ANTIMAGNETIC'. No hallmarks for silver purity (like 925 or a lion passant) are present.
Construction Details
Machine-stamped screw-down case back; die-cast or machined base metal case; integrated lugs for spring bars.
Functional Features
Threaded screw-back for water resistance; knurled crown for mechanical adjustment; antimagnetic shielding properties noted.
Handle & Grip Details
Knurled winding crown (likely plated base metal) located at the 3 o'clock position; original attachment to a strap via the lug holes.
Craftsmanship Details
Purely industrial machine-made production; limited hand-finishing; functional rather than artisanal execution.
Authentication Indicators
Markings are consistent with inexpensive 1960s tool watches; wear patterns show base-metal exposure (proving it is not solid silver); absence of any precious metal hallmarks.
Origin & Manufacturing
Likely Switzerland, Japan, or Hong Kong; typical of mass-production horology exports from the mid-20th century.
Era & Period
Mid-Century Modern (c. 1950s-1970s); characterized by the rise of 'tool watches' and the use of stainless steel over precious metals.
Age Estimate
Circa 1960-1975 based on the 'waterproof' terminology (later replaced by 'water resistant') and the diver/skier graphic style.
Cultural Significance
Represents the democratization of 'sports watches' for the general public following the prestige of brands like Rolex and Omega in the mid-century.
Condition Notes
Fair/Poor. Significant corrosion and pitting on the lugs; scratches on the case back; plating loss; the crown is heavily worn. Structural integrity is intact but cosmetically degraded.
Value Estimate
Minimal market value ($5 - $20 USD); primarily valued for parts or as a low-end vintage curiosity rather than silver content.
Care & Maintenance
Avoid chemicals or silver polish as they will strip remaining chrome plating; clean with a soft dry cloth; keep away from moisture due to compromised seals.
Similar Pieces
Generic vintage Timex, Seiko, or Caravelle sports watches. Distinct from silver luxury watches which would bear the .925 or .800 hallmarks on the inner or outer case back.
Interesting Facts
The use of '100% Waterproof' was largely banned in ಹಲವು jurisdictions by the early 1970s due to consumer protection laws, dating this piece before that regulatory shift.
