The Cartier Santos de Cartier reference WSSA0055 is a limited edition luxury sports watch initially designed for the Middle Eastern market. This large model features a 39.8mm wide and 47.5mm lug-to-lug stainless steel case, distinguished by a black amorphous diamond-like carbon (ADLC) coated bezel. The most striking element of this timepiece is its emerald green dial, which utilizes applied Hindu-Arabic numerals rather than the traditional Roman numerals synonymous with the collection. The watch is protected by a scratch-resistant sapphire crystal and an octagonal crown set with a green faceted synthetic spinel, ensuring water resistance up to 100 meters.
Internally, the watch is powered by the Manufacture Caliber 1847 MC, an automatic movement that provides a power reserve of approximately 40 to 42 hours. Its primary complications are focused on timekeeping and a date display, which is positioned at 6 o’clock and features a custom date wheel with matching Arabic numerals. For versatility, the timepiece is equipped with Cartier’s QuickSwitch interchangeability system, allowing users to easily swap between the included black rubber strap and a deep green alligator leather bracelet.
General reviews of the WSSA0055 highlight its bold and culturally significant design, often praising the dynamic nature of the green dial as it shifts from bright emerald in sunlight to a brooding dark green indoors. Enthusiasts appreciate the matte finish of the ADLC bezel as a sporty alternative to the typical high-polish steel versions which are often cited as scratch magnets. While the large size provides a significant wrist presence, the curved case and integrated strap system are noted for maintaining the exceptional comfort the Santos line is known for. Some minor criticisms occasionally mention the relatively standard 40-hour power reserve compared to newer movements in the industry, but the watch is overall regarded as a highly collectible and conversation-starting piece due to its limited availability and unique aesthetic.
