Signature is our modern take on the iconic Calatrava watches from the 1930s to 1960s, built around their most collectible traits: jumbo cases, Breguet numerals, and spade hands. Custom heat-blued hands, deep engraved details, and a manual-winding Sellita SW210-1b movement bring vintage character together with modern refinement. Vertically brushed dials and a sapphire exhibition back complete the design.
