I'll never understand what gives that species of Japanese horologists such an unusual sense of visual layout. If you thought TokyoFlash's watches were bugged out, check out the Seahope line of watches, designed by company founder Yasushi Kimura.
Said Kimura of his motivations, quoted in the now-sadly-defunct PingMag,
Simply put, people like light and illuminations - it just enhances any accessory; especially in Japan, where it gets dark so early.
For example, mobiles are just so part of our daily lives now and they have become very accessorized in trying to be unique and user-friendly with their displays. I think watches are just another accessory and LED lights give off an illumination everyone enjoys. The lights are like those small insects in the night, those bugs that can light up.
