·I use my chronos for timing tasks at work, as I charge by time spent.
Indeed, this hobby is supposed to be fun I thought. These are all toys in the end, because I could accomplish all that my chronograph does and much more just using my phone. So really if one has a "justifiable need" for one model over another (or for having a watch at all) is kind of irrelevant in the big picture, at least for me. Different strokes...
I use it for long shutter releases (mechanical shutters) - click chrono and cable release at the same time. Very handy for very long release in the multiple minutes range. I did a series of exposures (on film- can’t do it in digital), where I left the shutter open for a series of long exposures (in the hours each range) of the night sky in the open desert of Arizona- you could see the Stars spiraling around the North Star. Speedy timed each of those.
I use mine to time our setlist for my band. Most shows we play are 20-30 mins sets so being on-time and not overplaying is a MUST!
