Found a buyer for the Ultra. Replaced it with a Garmin Instinct 2x. 22 days of battery on a 55% charge out of the box. I like that.

Jarringly different aesthetics and design. Kinda bumps the GShock out of the lineup, but leaves room for my field watch and two others.

A Garmin Instinct watch on a wrist showing 22 days of battery life remaining.
