Okay, this mod is attached to me, not to Ruby, but it will be on board when ever I'm riding!
Just got this new Citizen chronograph.
Chronographs have been a part of racing tech for as long as cars & tracks have been around. This Citizen (model AT8124-83E if you're interested) is a quartz chrono accurate to 1/20th sec, and boasts a scratch-proof sapphire crystal and a tachometer bezel. It also synchronizes with the atomic tower each night and has a perpetual calendar good through the year 2100. Solar powered so it never needs a battery change.
Old-guy awesome! 🤠
