Measuring precise ages in astronomy is a very difficult task, but star clusters often provide the best opportunities to make age determinations. Eclipsing binary systems in star clusters can produce high-precision measurements of the masses and radii of the two orbiting stars, and an eclipsing binary close to the cluster turnoff can lead to a precise age. We performed a study of the totally-eclipsing binary star V12 in the ( 1.0-1.6 Gyr) open star cluster NGC 6939 using photometry from the Mount Laguna Observatory 1 meter telescope and radial velocities using the 9-meter Hobby-Eberly Telescope. We will present precise masses and radii for the stars, and a new determination of the age of the cluster.
