Left ☑Contrasting copper tone creates visual interest ☑More apparent case sharpness like CJ said above ☑Date window, for people who like the extra complication (or people of a certain 'vintage' who actually use it) ☑Patina looks more even ☑"Swiss" sign Right: ☑More unified overall colour scheme ☑Dial symmetry (no date window) ☑Doesn't have those weird black markings on dial ☑I actually prefer the right 'shield' logo ☑Hands free of tarnish Not sure if any of the above is due to camera artifact, lighting etc. 55:45 Left... are you buying or deciding which one to sell?
