Cobalt Rail Dial · Archive Blue is a curated vintage wristwatch prepared for the Collectorium T launch selection. The dial and case were composed around legibility rather than decoration, giving the watch a restrained workshop character.

Its visual identity combines chrome-plated cushion case with woven nylon strap, a graphite, copper and tobacco brown palette, and a compact cushion case with short lugs. Recorded display dimensions are 38 mm case; 19 mm strap. The gallery documents gentle handling wear with no structural loss; one invented geometric maker symbol; no readable lettering. Each image is a separately composed camera view of the same presentation piece. This presentation record is informational only; ownership, maker attribution, certification, scarcity and provenance verification are outside its scope.
