We have good documentary evidence for the 110.253 B reusing the barrel Carrera's CdG dial. The 110.253 G and 110.255 have bespoke dials. But now this is the second time I have seen a 110.253 with the correct handset using a fumé dial. Using the F dial wouldn't require anything over and above the B dial in terms of handset, so I'm starting to lean towards these being genuine, just not documented in sales literature.

Two samples isn't really definitive (though it is as many as I have seen of the silver "yachting" Carrera, in slightly different circumstances - one is a bespoke dial, the other a Heuer-performed dial transplant between two generations of Carrera) so I'll ask if people could have a look through their photo archives and see if they turn up any more examples. To be specific, what I'm looking for are late second gen Carreras, preferably also showing caseback, with the brown/smoke/fumé Côtes de Geneve dial. If I get enough, it should make for a definitive answer on whether they left the factory as 110.253 Fs or have had a dial transplant somewhere along the line.

Thanks, Mark
