Visual Description
The Ref. 2378 is the Pasha in stainless steel — the version that transformed Genta's 1985 gold design into an accessible daily-wear sports watch. The 38mm round case retains every signature detail: the screw-down crown cap with cabochon sapphire on a security chain, the rotating calibrated bezel, and the sapphire exhibition caseback showing the Cal. 191 movement through eight screws.
The silver guilloché dial carries the Pasha's characteristic geometry: a square minute chapter ring centered within the circular case, with printed black Arabic numerals at 12, 3, 6, and 9. A date aperture sits between 4 and 5 o'clock. Blued steel lozenge hands with luminous inserts provide legibility, while the inner minutes ring adds a layer of technical detail to the dial's composition. The integrated steel bracelet matches the case in both material and finishing — a mix of brushed and polished surfaces that handle daily wear better than the all-gold first series.
Reference Significance
The Ref. 2378 is the model that proved the Pasha concept at scale. The first-series gold references (820901, 820903) established the design, but gold-only production limited the Pasha to a niche audience. Steel changed the economics: the 2378 brought Genta's design below the precious-metal threshold and into competition with the broader luxury sports watch market.
The Cal. 191 — a 27-jewel automatic with 42-hour power reserve and rhodium-plated finishing — gave the steel Pasha genuine mechanical credibility. This was not a quartz concession to a lower price point; it was a fully specified automatic movement with decorative finishing visible through the exhibition caseback. The 2378 demonstrated that Cartier could deliver mechanical substance in steel, not just gold.
For collectors, the steel 2378 represents the most practical and representative vintage Pasha. It is the version most people wore, the version that built the model's reputation, and the version that remains most available on the secondary market.
Historical Context
The 1990 introduction of steel Pasha models marked Cartier's full commitment to the luxury sports watch category. The Santos had opened the door to steel in 1978, but the Santos was Cartier's own design. The Pasha was a Gérald Genta creation — and producing it in steel placed Cartier in direct competition with Genta's earlier work for Audemars Piguet and Patek Philippe. The Royal Oak and Nautilus were both born in steel; now Genta's Cartier design would compete on the same terms.
The Ref. 2378 also marked the beginning of the Pasha's expansion into multiple complications and sub-lines. Through the 1990s, the Pasha family grew to include chronographs, GMT variants, the Grille, and the smaller Pasha C. The 2378 remained the foundation — the standard three-hand automatic from which all variations departed.
What to Look For
The Ref. 2378 is well-documented and relatively straightforward to authenticate. Confirm the Cal. 191 movement through the sapphire caseback — it should be a 27-jewel automatic with rhodium plating and the characteristic oeil-de-perdrix (bird's eye) decorative pattern. The reference number should be engraved on the caseback.
The crown cap is the most common point of damage on surviving examples. Check the cabochon sapphire for chips or cracks, verify the security chain is original (consistent link size and finish), and confirm the screw-down function works smoothly. The rotating bezel should click firmly — worn or loose bezels indicate heavy use and potentially water ingress.
On the bracelet, check for excessive stretch between links — the integrated design means replacement is expensive and sourcing original-specification bracelets for 1990s production is increasingly difficult. The fold-over clasp should close securely with the Cartier logo intact and unabraded.
Water resistance should not be assumed on any 30-year-old watch regardless of original specification. Have the seals tested before any water exposure.
