Hi John,
there were two versions on these with angled and flat subdials, ask for numbers between the lug and bridge should be Heuer Leonidas signed.
Case looks original, Gübelin was a retailer.
All in all watch looks good and legit.
If you have my book a panda dial is shown on page 141/142 with the angled recessed subdials.
If it is the halem/primetime one I have even seen it in metal at the munich show and it was recently serviced.
Cheers

: Morning

: Just came across this watch listed on Chrono 24 - I am hoping to
: buy a dato 12 white on white to complete the set.

: Looking at it it appears to be a Dato 12 but when I compare the
: image with the images on "on the dash" this looks like
: the Clebar version as the sub dials are inset.

: Curiously though the watch is branded as a Heuer not a Clebar. Can
: anyone enlighten me?

: Also is Gubelin a retailer well known here?

: Many thanks
