Hii,.....I owned GP wwtc BMW Oracle ltd edt in Steel with rubber strap. Love the watch and have no issue with the rubber strap its comfortable trust me. I dont see any scratch on the strap. The wwtc is beautiful, easy to use and a very practical watch if you are a frequent traveller that jumps from one time zone to another or you have your love ones staying in another timezone. Anyways, I just love the dial like u said it reminds u of PP5110. JLC also has a similar watch but its way too big and the dial is not as nice as GP wwtc or BMW oracle wwtc. I prefer the steel case than the titanium coz its heavier than the titanium. But if u want comfortable try the new Piaget polo 45 its in titanium & the strap is rubber its the most comfortable rubber strap I've ever worn with micro adjustment but not a traveller watch, GMTor time zone indicator.
