FWIW, my local AD believes that almost all of the current F1 collection is going to be shortly discontinued - as evidenced by the fact most models are now on clearance sale at major retailers.
My prediction is that we’ll see the return of the Formula One at some point this year, possibly to coincide with the start of the new F1 season. I would guess they’ll be heavily inspired by the originals but in a larger case size, quartz movements, and made from some kind of carbon composite case (like the Tissot Sidderal) to offer an ‘F1’ inspired link without actually making the watches out of stainless steel. Expect to see plenty of collaborations with various brands/drivers/events in the future based on these models.
I would guess an £800 £1000 price point as a result - lower than the current range, but not MoonSwatch cheap. The three hand Carrera will become the new entry point to mechanical TH ownership going forward.
TAG Heuer’s range is now a pretty expensive one compared to five years ago, and I think it badly needs a recognisable, desirable entry-point to the brand. A revitalised Formula One will give it just that.
