Heat-Treated (HT) Blue Dial & Hands
HT Blue Hands, 23% Larger Hour and minute hands now run 23% larger with expanded luminescent surface area, easier to read at a glance, brighter in the dark. Each hand is heat-treated to a deep cobalt blue, achieved through controlled thermal oxidation, not paint or coating.
HT Blue Indexes Every index casing on the dial is finished in the same heat-treated blue, pulling the whole face into a single visual language.
HT Blue Subdial Rings (at 12 and 6 o'clock) The chronograph subdials are framed in heat-treated blue rings, tying the dial architecture together top to bottom.
