Hi folks,
After put up the inquiry,all the way to the local AD for a look.
From my observation,everything is fine except that for Leman collection the case is usually restrict to 40mm and the case construction is double ring case.(that is 2 ring on the outer part of the case)this part kill the look on the watch,that is of course my opinion.It has overall make the watch look tiny furthermore this is a chrono complication.Therefore,has made the watch look small and cramp.
Love the red stitches and red indication on the dial.Oliver mentioned the gold rotor with writen peking-paris,this part look nice and unique.
Finally,i abandoned the idea/intention.
Thanks for all the pictures and information,Oliver!
