The Evolution 9 geometry retains the brand's signature alternating light and shadow with Zaratsu-finished surfaces.
Ever Brilliant Steel offers nearly twice the corrosion resistance of standard steel and a brighter lustre.
The redesigned bracelet, previously on 37mm models, now features a classic taper and a micro-adjust clasp across the 40mm and 37mm sizes.
The Spring Drive models switch to the 9RB2 movement, which is more accurate (±20 seconds per year) but has a reduced power reserve of 3 days compared to the previous 9RA2's 5 days.
The Evolution 9 design language is a modern interpretation of the 1967 44GS, focusing on legibility and wearing comfort with broader hands and markers.
The use of hairline finishing is expanded, with mirror-polished surfaces strategically placed to stand out more strongly.
Ever-Brilliant Steel has a PREN of over 40, significantly higher than conventional 316L or 904L stainless steel.
The 9RB2 movement achieves its accuracy through refined quartz oscillator processing, IC design, and packaging, with a regulation switch for service technicians.
