I think I would agree with Mark on this and leave the original dial. I think the provenance of it would weaken with a redial, after all I've not seen a decent Heuer redial yet! and with Heuer's it's all about the dials.............I doubt it would be too hard to find a genuine replacement, get the watch up and running (depends on the level of water damage to the movement) with a few other cosmetic bits and then ponder on getting the McLaren lettering put on the replacement dial. The nice big clear photo of the other watch in the original thread shows the sizing, placing and font clearly so I think it could be replicated well. I would then keep the original dial tucked away in its current state.

Time for a WTB over on Chronotrader for a dial and a few other bits to bring this one back, unless we can round some up on here? I've got a correct inner bezel so will drop Adam a message.
