: I'd say it would be pretty much impossible to put hard numbers
: against these nowadays, though we can of course generalise.

: The white on black date wheel is only ever shown on CHNs, and I've
: only ever seen it on this model, so we can make a reasonable
: assumption that it is restricted to CHNs only - Ss and CHs are
: always shown with the "traditional" black on white
: date wheel.

: Once we do that, we can look at CHNs in the catalogues. First shown
: in 1970, the CHN makes an appearance with the white on black
: date wheel and continues to do so until the 1977 catalogue. It
: remains on sale for a couple of years at that point. I doubt
: annual production of 1158s was particularly smooth and certainly
: later on, I expect there were more or less made to demand so
: production may have been tailing off by the time the date
: wheel changed.

: Certainly, given the black wheel ran from 1970 to 1976 and the
: white only 1977 and 1978, maybe a year longer if a customer
: asked very nicely, it's probable that the majority have black
: date wheels.

: : The pulso seems extremely rare

: Very definitely. Heuer were proud of the pulsometer invention, but
: it's not something that would have been useful for, or perhaps
: appealed to, their customers. Certainly not as much as the Tachy
: version, with its links to glamorous motor racing rather than
: the more prosaic taking of pulses! Perhaps nowadays it would be
: a case of you get what you're given, but Heuer made the choice
: available to the customer... and from what I've seen, those
: customers stayed away from pulsometers in droves. Which makes
: them all the rarer and more desirable today. I can't see any
: watch dealer taking a pulse watch on spec and expecting to sell
: it, I reckon these were made to special order.

: While we're on the subject of rare first generation Carreras, the
: first execution Tachy on a black dial is another rare bird. I've
: long lost count of how many red-scaled silver dialled Tachys
: I've seen, but black Tachys I can count on the fingers of one
: hand. Never seen a Deci or Pulse black dialled first execution
: watch; I'm doubtful they exist but would love to see one if they
: do.

: how many panda dials have we seen,

: A fair few. Some have been Carrera 30s, and I find that a less
: desirable movement (the Valjoux 7730) than the venerable Valjoux
: 92 in the Carrera 45, regardless of whether the dials contrast
: or not. With panda dials, it pays to look closely - I'm not
: convinced that all of them are as they should be, or as they
: originally were.

: There are quite a few uncommon Carreras dotted around the range.
: 73655 S, 110.255, 110.571 in addition to those above are some
: examples of watches that are harder to find than their siblings.
: Yachting markings 1153 in a silver dial, rather than blue? I've
: seen a grand total of precisely one.
