Baltic Prismic StonevsSignum Cuda GMT

Owners and reviewers widely praise the Baltic Prismic Stone for its striking and unique natural stone dials, with specific mentions of the bloodstone and red agate variants being highlights. The watch is noted for its refined, retro dress watch aesthetic, featuring a well-finished 36mm bi-metal case combining stainless steel and titanium, and a slim profile measuring 9.2mm or 9.5mm thick. The hand-wound movement, either an ETA Peseux 7001 or a La Joux-Perret D100, is generally seen as reliable, offering a 42-hour or 50-hour power reserve respectively. However, some owners find the collection overpriced and the small, recessed crown uncomfortable for winding. The Milanese bracelet is also a point of contention, with some finding it may not articulate well for smaller wrists. Accuracy figures vary, with one owner reporting +1/+2 seconds per day and another around -6 seconds per day.

Owners widely praise the Signum Cuda GMT for its striking Lapis Lazuli and thermally blued meteorite dials, with one owner finding the meteorite dial's light play stunning. The watch is also lauded for its exceptional lume, with one user reporting it "glows for hours and hours" and outperforms many more expensive watches. However, a significant concern raised by multiple owners is the weak lume on the hands, which is noted as being significantly weaker than the dial. One owner reported crystal fogging during kayaking, suggesting a failure of the 200m water resistance, and expressed dissatisfaction with the brand's response and warranty. The bezel action was initially stiff for one owner but improved after oiling. The 42.5mm titanium case features a scratch-resistant coating. Overall, owners are divided, with some praising the unique dials and strong lume while others cite concerns about hand lume and water resistance.
