Hi,guys, I need your help on deciding between 5013 and 5016. They both are very nice watch. They both have Retrograde date. But 5013 is automatic without tourbillon. Ref. 5016 has tourbillon but manual winding. I would prefer 5013 because of its look and automatic movement. So what do you think? I have to pre-order both watches from the dealer, so I cannot see both watches and try them on personally. Need some thoughts and insights from you. Many thanks in advance.
