The Singer Divetrack SR401 is a highly specialized mechanical dive chronograph built around an unusual display: its chronograph hours, minutes and seconds sit at the center, while time is shown around the dial’s periphery. Singer pairs that layout with three color-coded zones it calls Chill, Dive and Fly. The concept is distinctive, but it does not replace a dive computer, decompression planning or aviation guidance.
What makes the Singer Divetrack different?
Singer Reimagined describes the SR401 as an “Automatic 24H Central Chronograph.” Instead of arranging conventional chronograph subdials across the face, its AgenGraphe movement centralizes the chronograph display: jumping hours and minutes, plus sweeping seconds. The regular time indication is peripheral. Singer presents the arrangement as a way to make elapsed time and its dive-oriented dial zones the focus of the watch. Singer’s SR401 product page
The design grows out of a specific question about reinterpreting the dive watch. On Singer’s collection page, Co-Founder and Creative Director Marco Borraccino says: “The Divetrack began with a question: how do you elevate one of the most iconic tool watches ever created? The answer was not by revisiting the past, but by engineering the future. The Divetrack is our most radical expression yet – purposeful, powerful and poetic.” Singer’s Divetrack collection page
How Singer’s Chill, Dive and Fly zones are intended to work
Singer divides the 24-hour dial into three zones tied to a dive-day narrative. These are the manufacturer’s intended interpretations, not a stand-alone safety system or substitute for professional dive and flight guidance. Singer’s Divetrack collection page

The concept gives the dial a clear thematic logic, but divers should use appropriate dive planning tools and follow applicable safety guidance. The watch’s Fly zone should not be used to determine when a particular person can safely fly after diving.
