alvieri WMO Switcher

I was inspired by this beautiful Alvieri Kickstarter project: https://www.kickstarter.com/projects/alvieriwatches/alvieri-elegant-watch-with-a-really-lively-dial/description, but I wanted to put a WatchMaker spin on it. Everything but +Terry Zahn's watch hands is WatchMaker. Current weather condition tracks across the window in proportion to sunrise/sunset. Maths courtesy of a +Paul Hurst code that I recycled from one of my older faces. Tap center to toggle current temp and today's weather (forecast icon, high and low temps) and then forecast for the next two days. Tap the date indicator to cycle through colors choices.
