I am trying to decide between a typexxi 3810 ti and a type xxi 3810st The st comes equipped with 584q/2 with silicon pallets and a flat silicon balance spring where is the titanium version comes with the caliber 584/Q1 I prefer the titanium version for overall looks however is there a huge advantage to the q 4 caliber? Thank you in advance for your comments. Best regards, Tony
