Crown & Pushers
Small, fluted push-pull gold crown, properly sized for the case diameter to maintain a streamlined profile.
Bracelet or Strap
Vintage gold Milanese / Mesh bracelet with a folding jewelry clasp. The tight weave suggests a high-quality manufacture popular during the mid-20th century.
Caseback Details
Solid, snap-on caseback. Likely features gold hallmarks (e.g., Helvetia head) and serial numbers on the interior rather than the exterior.
Movement Type
Manual / Hand-wound mechanical movement. Likely an IWC in-house Caliber 41 or Caliber 43, known for their high-quality finishing and reliability in small formats.
Water Resistance
None. Rated as 'not water-resistant'. Moisture and humidity should be strictly avoided to protect the vintage movement and dial.
Origin & Provenance
Swiss Made. Manufactured in Schaffhausen, Switzerland. Features an in-house movement.
Age Estimate
Circa 1955-1965. The use of the full 'International Watch Co.' text rather than the later 'IWC' logo and the stylized Arabic numerals support this dating.
Cultural Significance
Represents the height of the mid-century 'Cocktail' era where a watch was an essential accessory for formal attire and high-society social gatherings.
Condition Notes
Good to Very Good vintage condition. Dial shows some spotting/patina (typical for age). Case appears well-preserved with light surface wear. Bracelet shows no significant kinks or fraying.
Value Estimate
$1,200 - $2,500 USD. Value is heavily driven by 'melt value' of the gold and the desirability of the IWC brand name.
Care & Maintenance
Mechanical service recommended every 5-7 years. Avoid all water contact as gaskets have likely perished. Clean the gold mesh with a soft jewelry cloth to prevent oil buildup.
Similar Watches
Vintage Omega Ladymatic, Rolex Orchid, or Patek Philippe Calatrava Ladies. These alternatives offer similar sizes but IWC is often preferred by those valuing 'engineer-focused' provenance.
Interesting Facts
During this era, IWC was one of the few brands that insisted on manufacturing high-grade mechanical movements for women's watches rather than using cheaper, generic movements, making these highly respected by horologists.
