mainspring
« on: February 24, 2013, 09:50:43 AM »
Hi guys. I have a Tissot Veloci-T automatic chronograph that using ETA C01.211. I just wondering how the mechanical chronograph function get its power to work? Does it using the same mainspring that power the watch small second? Or the chronograph function has its own mainspring?
