I feel very fortunate to have acquired one of the last Octa chronos in production. The technical look on the dial face appealed to me immediately. I use it every day - for the time when I can really use a chrono to make life easier. This ranges between stirring a soup, although well below high-vapor conditions, taking a strenuous walk from A to B and back, and pre-heating my vacuum tube equipment. In short a chrono, by any definition, is there to be used!
It has a function. It is a utility.
However, it does require practise to distinguish the elapsed minutes. The jumping minutes on the Datograph are ideal, if "only" for 30 minutes. And the Octa Chrono does not have a totalizer for 12 hours. But 1/100 sec is completely meaningless to me.
So, when the time comes, I just reach for another watch. If there is none within reaching distance, I could live with this all day, all night long. Or months. Just look at the beautiful calender and where the window is placed!
Then look at the Octa Calendrier.
Look at the Chronomèter Souverain...
All of which I wear and enjoy.
And of course, there are the others - if not from F.P. Journe!
