The Panthère de Cartier collection was introduced in 1983 as a direct evolution of the brand’s signature square-case designs, with this reference W25029B5 representing the small 22mm version in a steel and yellow gold configuration. This particular model features the collection’s defining design elements: a square case with rounded corners measuring 22mm in both width and height, creating a perfectly symmetrical profile. The case and bracelet combine polished stainless steel with 18k yellow gold accents, utilizing Cartier’s signature two-tone construction method where the gold elements are integrated into the bracelet links and case bezel rather than being surface treatments. The white dial maintains the classic Cartier aesthetic with black Roman numerals, blued steel sword-shaped hands, and the hidden signature at the seven o’clock position. The bracelet employs the collection’s characteristic link design that provides both flexibility and security, with a concealed deployment clasp that maintains the clean visual lines.
This timepiece is powered by Cartier’s caliber 057 quartz movement, which provides reliable timekeeping with minimal maintenance requirements. The movement operates with a precision of ±15 seconds per month and features a battery life of approximately 42 months. As a time-only watch, it maintains focus on the essential function of hours and minutes without additional complications, which aligns with the collection’s original purpose as an elegant daily wear piece. The sapphire crystal provides scratch resistance while maintaining excellent legibility. The case back is solid stainless steel, consistent with the model’s positioning within Cartier’s offerings during its production period. Water resistance is rated to 30 meters, suitable for accidental splashes but not for swimming or submersion.
This example presents in mint condition with no visible signs of wear on the case, crystal, or bracelet. The two-tone finish retains its original polishing without any scratches or desk-diving marks. The bracelet shows no stretch and the clasp mechanism functions precisely. As noted, this watch does not include original papers or documentation, which is common for examples of this age that have been through multiple owners. The Panthère de Cartier in this steel and gold configuration has become increasingly sought-after among collectors due to the current market preference for integrated bracelet designs from this era. Its limited production run and the specific combination of materials make this reference particularly collectible within the vintage Cartier market. The value of these pieces has shown consistent appreciation, especially for examples in this condition level, making it both a wearable timepiece and a solid addition to any serious collection of important twentieth-century watch designs.
