Singer specifies 300-meter water resistance, a unidirectional 60-minute bezel and a Grade 5 titanium case. Its “Chill,” “Dive” and “Fly” zones are intended as elapsed-time and caution indications—not replacements for dive planning or safety procedures.
What is the Singer Divetrack SR401?
Singer Reimagined calls the Divetrack its first committed dive-watch project and describes it as “The ultimate tool watch.” The model name on the current product page is Singer Divetrack SR401. Its unusual feature is the way it separates chronograph and ordinary time: the chronograph is read from the center, while the time of day appears around the dial’s perimeter. Singer Reimagined’s Divetrack SR401 product page supplies the specifications below; they are manufacturer-published details, not independently measured results.
How does the central chronograph work?
The automatic AgenGraphe movement puts its 24-hour chronograph indication at the center of the watch. Singer describes the hours and minutes as jumping indications and the seconds as sweeping. Ordinary time is displayed separately at 6 o’clock on a peripheral indication. That layout gives the Divetrack a different reading logic from a conventional chronograph with small subdials.
Singer lists 479 movement parts, 56 jewels, a Swiss lever escapement and a 72-hour power reserve. These are published specifications; the reviewed product information does not establish independent verification of the movement’s performance or reserve.

What do the Chill, Dive and Fly markings mean?
Singer’s collection page divides the central counter’s 24-hour scale into three intended-use zones:
| Zone | Indicated period | Singer’s stated intent |
|---|---|---|
| Chill | 0–6 hours | Guides the surface interval for nitrogen release. |
| Dive | 6–18 hours | Indicates a window for safe re-entry into the water. |
| Fly | 18–24 hours | Marks a cautionary threshold before air travel. |
These descriptions explain Singer’s intended indications, not a substitute for dive tables, a dive computer, decompression procedures or medical advice. Singer’s collection page does not establish that the markings can determine an individual diver’s safe return to the water or readiness to fly. Singer’s Divetrack collection page also carries co-founder and creative director Marco Borraccino’s brand-positioning statement: “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.”

What is specified for diving?
Singer specifies a marine-grade 316L stainless-steel bezel with a unidirectional 60-minute ring made from ceramised aluminium, with Super-LumiNova indications. The crown screws down at 4 o’clock. A start/stop pusher at 2 o’clock has a red-guard ceramic-coated protector, and the reset pusher is at 10 o’clock. A helium release valve sits at 8 o’clock.
The brand states water resistance of 300 meters (1,000 feet) / 30 ATM and describes the Divetrack as designed as a professional diving instrument in its official FAQ. The reviewed Singer pages do not establish independent water-resistance testing or a particular certification standard, so those claims should be understood as Singer’s specifications and characterization.

Straps and fit considerations
Singer lists two strap options: an adjustable black rubber strap and a diving technical textile strap with Velcro fastening. Both are listed at 22 mm, with a stainless-steel folding buckle. That width alone does not establish that a generic 22 mm strap will fit: the reviewed product information does not confirm compatibility with arbitrary straps, attachment geometry or buckles. Check fit and hardware compatibility before buying a replacement.

What the Divetrack’s specifications do—and do not—tell you
The Divetrack’s unusual central display, diving-oriented hardware and three named zones make its concept clear: it combines chronograph timing with indications Singer associates with time between dives and before flying. The numbers and features here describe what Singer publishes, not proof of real-world performance. The reviewed information does not provide a hands-on assessment, independent test results or a directly comparable alternative, so it cannot establish how the watch wears or performs against other dive chronographs.
