: I know I should have researched it first before buying it ..

: The case size is advertised as 40mm. All the case size I found on
: “on the dash” site is 42.5mm ... And the color of the hands
: (vs the markers - orange / red), I could not find like that on
: the site.

: Can anyone shed some light on this ? Thanks

Thank you all for all your responses. The watch somewhat works. Thinking if I should return it. I runs but the reserve power is only like 40 min and the chronograph runs for about a minute and stops. A local watch maker quoted $850 for main spring, gaskets (back and crystal), crown (I thought the crown is only cosmetic but he told me its also functional )….Do you know of a trustworthy watchmaker that services Heuer ? Thanks again
