Yep, I've had both MK2 & MK3 C60s to compare to the latest Aquis, although I only handled the MK3 briefly before returning it.
The Aquis is definitely better than the MK2 in quality imo. At first glance and handling it may not appear entirely obvious, but it's something I picked up on more with ownership/frequent wear.
Re. the MK3, in terms of build quality, there is very little (if any) discernible difference with the Aquis. CW have done a solid job with it, although I haven't lived with a Mk3 for an extended period so the above may apply.
I didn't attempt to wear the MK3 bracelet due to the return, but if it's anything like as comfortable and well screwed (sorry pinned
) together as the Oris, they've done really well.
For me though, build quality is just one measure when judging watches. All subjective of course, but if I were to compare aesthetics, comfort to name a few more, the Oris wins quite comprehensively imo.
That said, CW changed the game when it comes to pricing and will always take some beating. I feel even the current C60 represents incredible vfm.
Lets be honest though, if CW were a traditional manufacturer with AD networks, large-scale advertising/sponsorship etc, we'd probably be talking similar prices to the Aquis, so it should be there or thereabouts.
As it is, a MK3 is £695 on bracelet with the ever-present 100off, whereas the Aquis can be sourced new on bracelet from an AD for less than £1100 now.
Is it worth ~£400 more? Can't answer for anybody else, but the answer is a yes from me.
I've posted this photo elsewhere, maybe even twice before, but everyone loves a pretty picture and it's all relevant ...
