watchOS and iOS Timers

When doing something like laundry, I like to put a timer on my phone. But when I put it on my phone, my Apple Watch won't sync up. In the leaked image of the Apple Watch Series 4, the Timer complication is visible. This is nothing new, but I'm hoping Apple would make the obvious choice to have timers set on iPhone sync up to timers on Apple Watch. This would let a user set a timer on their phone, and look at their watch to see it ticking down on the main watch face. Hopefully, this small change makes its way into watchOS 5.
