Deep, rich yellow gold with a high-polish mirror finish on the bezel and bracelet center links, and a contrasting brushed/satin finish on the outer bracelet links and case lugs.
Hallmarks & Stamps
Usually located on the case back, interior of the clasp, and between the lugs. Expected marks: '750' in a scales symbol, Helvetia head, or St. Bernard's dog head (Swiss assay), and maker's logo.
Dimensions Estimate
Case diameter approx. 26mm to 28mm (Lady size); lug width 13mm; bracelet length adjustable via removable links.

Aftermarket/Custom setting: Round brilliant-cut diamond pave dial and bezel; 4 rectangular/baguette-cut red rubies positioned at 12, 3, 6, and 9 o'clock as cardinal markers.
Clasp & Closure

Craftsmanship Details
High-precision milling for the case and bracelet links; aftermarket stone setting shows tight pavé work with hand-finished prongs on the bezel rubies.
Authentication Indicators
Weight is the primary indicator; genuine 18k gold is remarkably heavy compared to plated brass. Markings should be sharp/deep, not rounded or cast-looking. Ruby color depth and diamond fire are also critical for authenticity.
Origin & Maker
Likely Swiss-manufactured base (comparable to Rolex Datejust specifications) with aftermarket gemstone customization performed by a jewelry atelier.
Era & Period
Contemporary/Modern, reflecting the aesthetic of the Late 20th to Early 21st Century (1990s-today) luxury custom watch market.
Age Estimate
Estimated production circa 1995–2015 based on the bezel design and bracelet link profile.
Cultural Significance
Represents the 'Power Watch' era of the late 20th century, where timepieces transitioned from tools to status symbols and functional jewelry.
Condition Notes
Very Good; the gold shows minor hairline scratches (swirls) typical of soft 18k gold wear. Stones appear secure, though cleaning is needed to restore brilliance to the pavé.
Value Estimate
$12,000 - $18,000 (Secondary Market); value is derived from the net weight of gold (approx. $4,000-5,000 in melt) plus the considerable premium for movement, stones, and brand prestige.
Care & Maintenance
Clean with a soft brush and warm soapy water only; check gemstone prongs biannually. Avoid chlorine which causes 'stress corrosion cracking' in gold alloys over time.
