In terms of general appearance, this watch has not changed much compared to the old model; Spacious dial, elegant willow leaf-shaped hour and minute hands and Arabic numeral hour markers... Classic design never goes out of style. Chronograph counters are located at the six and twelve positions, adding a holistic balance and layered feel to the dial; vertical layout adds lightness and elegance to the dial surface. Arabic numeral bar signs are crafted with a highly textured engraving. The "6" and "12" signs covered by the meters reveal a splashing personality and liveliness, rather than disrupting the holistic aesthetic. The dense marking lines on the inside of the bezel give a design feel reminiscent of a precision measuring instrument and reveal the lineage of the Portuguese maritime chronograph.
