On my Ultra, when I lift my wrist for using my compass, or for timing an event, the display goes dim after 15 seconds or so - very aggravating. The only way I've found to keep it bright is to keep rotating the dial toward me (a brief turn every couple of seconds). When I'm using my Ultra for these events, I'm not concerned with battery longevity, I'm only concerned with what I'm doing at the time. Is there a non-invasive way to keep the brightness at a high level until I lower my wrist?
