: I purchased a Heuer watch from a discount
: jeweler in 1980. It has a tachymeter inside
: and can measure up to 30 minutes total stop
: time. The large stop hand is bright orange.
: I found one similar on this web site with a
: Champion spark plug emblem. I believe it to
: be a calculator, but am not sure. Tell me
: what I have. Thanks

Would you post some pictures [or email 'em to me] so we can help out. I am unaware of any Champion labeled Calculator models, does it have a "whiz-wheel" or Slide-Rule bezel or ???
