The Cartier Santos Galbée (Reference 187901) is a highly collectible vintage timepiece originally introduced in 1987. It is celebrated for updating the classic, rigid Santos layout with a curved, ergonomic case shape designed to wrap comfortably around the wrist.

  A "Tropical" Roman dial variant means the original cream or white watch face has naturally aged over decades due to UV exposure and humidity, oxidizing into a highly desirable, unique caramel, toffee, or golden patina.

• The Dial: Features classic black painted Roman numerals with a railroad-track minute track. True to Cartier heritage, a "secret signature" text is integrated into the VII or X numeral.

• The Hands: Traditional blued steel sword hands.

• The Crown: Octagonal steel crown set with a faceted blue synthetic spinel or sapphire cabochon.

• Crystal: Scratch-resistant sapphire crystal.

• Clasp: Fitted with a concealed, integrated folding butterfly clasp.

• Brand & Model: Cartier Santos Galbée 

• Reference Number: 187901 

• Case Dimensions: 29mm width (32mm including crown) x 41mm lug-to-lug length. It is considered a "large" model for its era but wears as a sleek unisex dress watch today.

• Thickness: A remarkably slim 6.5mm to 6.7mm, allowing it to easily slip under shirt cuffs. 

• Materials: Two-tone construction featuring a stainless steel case and integrated bracelet accented by an 18k yellow gold bezel and gold bracelet screws. 

• Movement: Low-maintenance Swiss Quartz movement with a quick-set date function. 

• Complications: Hours, minutes, seconds, and a date window at the 6 o'clock position.
