Have noticed a few watches where the first third of the dial is highlighted, enough to make me suspect there is a functional reason and not just fashion. Hopefully someone can educate me on its purpose? Is there a reason to highlight the first 20 seconds of a minute (the second numbers also being accented)? I thought I saw this on other brands, but when I search now I just see a few Seikos. Hopefully it is not some big 4:20 joke inside joke? A pictures below.
