The Tudor Big Block marked a major milestone for the brand as the first self-winding chronograph produced under the Wilsdorf umbrella, arriving nearly a decade before the venerable Rolex Daytona ref. 16520. For anyone with medium to larger sized wrists, the 40mm case is chunkier at 14.5mm in height and makes for a great off the beaten path choice for anyone looking for a high quality vintage chronograph.

This particular example, circa '93 features a silver "Panda" dial and is the rarest variant of the model with bi-directional rotating bezel. It has remained in stunning neo-vintage condition with a mint dial showing no lume loss whatsoever. The bezel insert also has no notable wear. The case has seen some light polishing in the past but still retains thick, even lugs with some chamfer still visible. It retains a correct 78360 with P9 date code and correct 589 end links. It remains tight, retaining full links (13). For the discerning collector, this piece also has punched warranty papers and both boxes. We are thrilled to offer this outstanding example in the shop.
