Below is a snipit from trc about the Gran Turismo new release.
Copyed over from TRC, the expanation for the movement
"the gen one is using ETA-A07111 movement and only two watch brands are now using this movement and this movement is not sold to third parties like ETA-2836-2, ETA-770 and other ETA movements. So we can only use A7750 to replicate this, at least I see they are observable same in major ways"
it makes sence, and makes me think about the IWC Big pilot as we were wondering if the valranges ETA-A07111 was being copyed to run in the IWCBP. This one factory is not involved or they may have delayed release of this one untill the movement was ready. I still think that we will see the IWCBP with a modded 7750 ticking away inside it, can our experts confirm if a power reserve can be fitted to a 7750?
I know what the post above says but now we see the centre seconds on a 7750 so that is a step closer so just the PR and the date wheel, oh and also an attempt at increasing the PR of the standard 7750 from 2 days upwards.
