JULIEN LE ROY QUARTZ TANK WATCH: IDENTIFICATION
A rectangular dress watch featuring a gold-toned base metal case with a stainless steel snap-back. The dial utilizes a minimalist two-tone white and champagne concentric circle design, minimalist baton hands, and a 'QUARTZ SWISS' designation at the six o'clock position. The case measures approximately 22mm in width excluding the crown, fitted with a brown lizard-pattern leather strap exhibiting significant verdigris accumulation at the lug attachment points.

- Standardized markings for mid-tier quartz Swiss-branded timepieces
WATCHMAKER'S ASSESSMENT
Vintage Watchmaker & Horology Specialist
The identification is based on clear dial signatures and case back markings consistent with known period fashion watches. Uncertainty remains only regarding the specific internal caliber (likely ETA or ESA quartz).
KEY EVIDENCE
- 1Quartz Swiss signature on dial denotes a battery-powered movement from the 1980s or later.
- 2Stainless Steel Back marking confirms the mid-case is base metal (likely plated brass).
- 3Verdigris (green corrosion) is characteristic of copper-based alloys used in plating under-layers reacting with salts.
- 4Case geometry and dial design are derivative of the Cartier Tank Must de Cartier series.
UNCERTAINTIES
- •Heavy verdigris may have compromised the integrity of the spring bars or leaked into the movement spacer.
WHAT WOULD IMPROVE CERTAINTY
- →Remove the case back to inspect for battery leakage or movement corrosion.
- →Discard the current strap and clean the lugs with a soft brush to remove verdigris.
- →Test the circuit and coil if a new 364 or 371 battery does not restart the movement.
CONDITION & GRADE
Grading breakdown
Case plating is intact but scratched; the dial appears clean without moisture damage, though the heavy green corrosion at the lugs suggests prolonged exposure to sweat or moisture.
Condition
Significant verdigris buildup at the spring bars and strap ends; the case shows micro-scratching through the plating. The strap is heavily worn and requires replacement for hygienic and aesthetic reasons.
