A Personal Favorite

Covered previously, but still a fave.  This is the Brellum Wyvern 5 Days.  Sometimes, something just hits you with a visceral sucker punch, and this one does that for me.

I love the dial.  Simple, but bold enough to read.  And the power reserve is a fun bit of splash with a touch of red to indicate you're low on juice.

The movement is a bit special -
