Subdial (minutes) on Chrono keeps running but Chrono not engaged? Is this an issue?

Moreover, anyone who’s sent their watches in recently should have this new spring and therefore the issue won’t occur again. Hope this helps guys!

Great info. I got my 26240 almost a year ago but haven’t had any issues, so we’ll see.
Could be more accurate so maybe I’ll send it in to have that addressed and mention this.
