Who was able to think to such a result?

: Really interesting watch. The catalog states it is property
: descendants of Ronnie. It would be interesting to know more
: about the provenance of the watch, particularly when it was
: presented to him by Jack Heuer.

: I have never seen this dial in this case, but it is possible that
: it came out the Heuer factory like that, as we have seen quite a
: few regular 1153 steel Carreras with the cotes de Geneve 'oval
: sub' dials. I believe these are accepted as correct watches.

: That's why I'd be interested when it was given to RP; if it was
: later in the production history of the 1158 then it is more
: likely the watch came out the factory like that.

: Really interesting watch; how many actual F1 driver 1158s are in
: collectors hands?

: I also love those milanese bracelets, they are amazing 'in the
: metal'.
