A few months back, APs new CEO mentioned that there will be a "re-imagining" of the then 42mm Royal Oak Offshore Chronograph line...
During the recent SIHH2014, they finally released pics and specs.
These 4 models are the "reimagined" ones...

Stainless steel slate grey dial with black subdials on black hornback strap. (New Black Themes?)

Stainless steel ivory/cream dial with chocolate subdials and brown hornback strap. (New Safari?)

Stainless steel black dial and subdial with red accents on grey hornback with red stitching. (Racing dial?)

Stainless steel blue dial with white subdials and yellow (according to AP spec sheet) accents on blue rubber strap. (Some are calling it the new navy and some calling it the royal blue)
Changes are welcomed in these 4 models.
Most people have been screaming for display casebacks. They delivered, all the new 42mm ROOs are fitted with sapphire display backs.
Some ppl (like me) are skeptical of the rubber pushers and crowns... replacement costs... durability and etc.
Again, they delivered... Now all the crown and pushers are ceramic.
Hands are now faceted for better legibility... looks to be the same like the hands fitted on the 44mm Offshores.
Crownguards are redesigned and now look more modern and up to date... just something about those lines.
What they did not do is fit the these new 42mm Offshores with ceramic bezels.
Thinking about it logically, i think it's a wise choice.
If they do fit these models with a ceramic models, it will push the price around the 44mm offshore range.
They keep the all stainless steel setup and keep the pricing around the same as the current (now previous) ROO 42mm range so that the entry cost for potential 1st time buyers is not too stiff (as if it's not already stiff... lol)
Those who still want a 42mm Offshore with ceramic bezels still have a choice (albeit limited) in the Limited Editions like the Doha LE, Ginza 7 LE, Sebastian Buemi LE and so on...
Some are also requesting it's time AP made a fully integrated chrono instead of the current modular setup using the caliber 3120 as the base... well... it didn't happen.
For obvious reasons I guess?
Launching a new in house integrated chrono movement will push prices high up again...
I think the best way for them to introduce new movement is with the 44mm Offshores first (since theyy are already expensive to begin with) and gradually trickle down the 42mm range.
I am quite excited with the release but these are not something that can be bought on a whim...
My current fav looks to be the Racing Dial ROO...
What about you guys?
