I completely agree with this. The PRS68 jarred for me not only because it sat uncomfortably with where I thought the strengths of the Timefactors lay: it seemed very odd for a British company to be producing a Smiths-branded homage to a very Japanese diver's watch. But also (and I'm being frank here), aside from the case, I thought the execution deeply flawed. The dial, hands and bezel insert appeared to have been modeled in the style of the dodgy third party parts that plagued so many 6105's that had been 'restored' by backstreet Philippine eBay sellers in the late noughties. I would encourage Eddie to shelve any plans for a 68 revival but if a smaller version remains on the cards, then why not model it around the first 6105 (i.e. the one that was actually produced from 1968 and not the one that appeared in 1970).
i.e This one:

The earlier model (6105-8000) has a 40mm case already and there would be no peril associated with down-scaling what was deliberately intended to be an expansive cushion case in the later 6105-8110. In spite of all that, I still don't think it's a good idea!
