Actor Chris Pratt spotted wearing a Cartier

Chris Pratt was recently photographed with a Cartier Santos de Cartier Diver on his wrist — reference W7100056 — a steel-cased sports watch that sits in an interesting and often underappreciated corner of the Cartier catalog. For a brand synonymous with the Tank and the Ballon Bleu, the Santos Diver is a quiet statement of intent: proof that Cartier can build a tool watch with genuine depth, not just visual polish.

The W7100056 is the 42.6mm stainless steel version of the Santos de Cartier Diver, water-resistant to 300 meters — serious dive watch territory by any standard. It runs on the Cartier Calibre 1904 MC, an in-house automatic movement with a 48-hour power reserve and a 28,800 vph beat rate, developed after Cartier invested heavily in movement manufacturing during the 2010s to reduce reliance on ETA. The case features the signature Santos octagonal bezel with exposed screws, here rendered in a sportier, more angular form than the standard Santos, with a unidirectional rotating bezel and screw-down crown. The bracelet integrates Cartier's QuickSwitch and SmartLink systems for easy strap changes and on-the-fly sizing.

From a collector's standpoint, the Santos de Cartier Diver W7100056 occupies a nuanced position. Cartier's sports watches have historically been overshadowed by Swiss sport watch titans, but the Santos family has enjoyed a significant rehabilitation in collector circles since the redesigned 2018 Santos line reintroduced the QuickSwitch system and sharper proportions. The Diver extends that momentum into genuine tool-watch functionality, and its relative scarcity compared to the standard Santos makes it a more distinctive wrist presence.

Chris Pratt's watch choices tend to skew toward robust, legible sport watches — consistent with the outdoorsman and action-hero persona he has cultivated both on screen and publicly. The Santos de Cartier Diver fits that profile without leaning on the obvious Rolex or Panerai defaults, suggesting either a deliberate collector's choice or a well-informed recommendation.

At a UK list price of approximately £6,650 — translating to roughly $8,300 USD at current exchange — the W7100056 sits at an accessible entry point for a genuine in-house Cartier sport watch. Grey market values have tracked close to retail, reflecting steady rather than speculative demand. For collectors looking past the usual suspects, the Santos de Cartier Diver remains a disciplined and undervalued choice.
