It runs at 21,600 vph with about 41 hours of power reserve, hacks and hand-winds, and has become the default affordable GMT for microbrands.

Owners widely praise the Signum Cuda GMT for its full lume dial, with one source noting "outrageous amounts of lume" that glows for hours, outperforming many more expensive watches. The thermally blued meteorite dial is described as stunning, and the Lapis Lazuli dial is also a point of admiration. The 42.5mm titanium case with a scratch-resistant coating is appreciated for its fit and finish. However, some owners criticize the hands' lume for being significantly weaker than the dial's. One owner reported crystal fogging during kayaking, suggesting a failure of the 200m water resistance, and found the brand unresponsive regarding warranty. The bezel action was initially stiff for one user but improved after oiling. The Signum Cuda GMT is available for around $500. Overall, owners rate the Signum Cuda GMT highly for its exceptional lume and unique dial options, though concerns exist regarding hand lume and water resistance.
