Dial Typography, Lume Application & Clasp Mechanics

Pay close attention to the transitions between brushed and polished surfaces along the case flanks and bracelet center links; each edge is hand-finished after CNC milling. A colorless anti-reflective sapphire crystal seals the dial against dust and moisture.
