Exposed Engineering

We took the rulebook of the garage and applied it to the wrist. Strip away what isn't load-bearing, keep what makes the machine work. The Edge Tech has no traditional dial, no hidden surfaces, no decoration covering the structure. Just the radiating bridges, the visible gears, and the Caliber BB-77S doing its job at 28,800 vph. What you see is what runs it.

The design started on the drawing board the same way a chassis does. We mapped the load paths, identified the components that had to be there, and questioned everything else. The hexagon case came out of that work, six sides giving the structure rigidity and a footprint that fits the movement without wasted space. The radiating bridges aren't decoration laid on top, they're the framework that holds the architecture in place, machined to do a job and shaped so you can see them doing it.

Removing the dial wasn't a styling choice, it was a structural one. A traditional dial covers the part of the watch that's actually interesting. We took it out and let the Caliber BB-77S take the front of the watch instead. The gear train, the barrel, the balance wheel, all of it on display. The exhibition caseback does the same job from the other side, showing the bi-directional rotor as it winds the movement.

Engineered by Subtraction

We built the EDGE Tech for the people who care about how things work. The engineers, the strategists, the ones who spend their time on tolerances and weight figures most people never think about.

The spec sheet reflects that: double-sided sapphire with anti-reflective coating, 100m water resistance, screw-in steel crown, integrated bracelet, and a black silicone strap. Both come with quick-release pins, so swapping between them takes seconds.

Nothing but the Chassis

Three references, same build, three different moods.

The A7 takes its cue from the hot end of the workshop. An industrial bronze tone runs across the 43mm hexagon case, brushed, polished, and chamfered in 316L stainless steel, with the same warm, lived-in quality you find on milled alloy components and heavy-duty precision tooling.

The C5 carries a light champagne gold finish across the 43mm hexagon case in 316L stainless steel, brushed, polished, and chamfered, with the kind of warm metallic surface you see on laboratory instruments and motorsport heat-shielding foils.

The 6D goes stealth. A matte black finish over the 43mm hexagon case, brushed, polished, and chamfered, the same anti-glare treatment used on race-cockpit instruments and prototype-class telemetry housings to absorb light and hold a low profile under high-contrast track conditions.

Inside Steller Engineering

We shot the Edge Tech where it belongs, in the workshops of Steller Engineering in the UK. Steller operates at the highest level of motorsport engineering, building and restoring race machines with the kind of precision tooling and tolerances most workshops never touch. Their team opened the doors so we could photograph the collection alongside the components they engineer every day. The setting matched the watch: calculated, exact, and built around the pursuit of performance.

Huge thanks to the Steller team for the access and the hospitality.
