Abstract: New extensive differential uvby photometry at the Danish SAT telescope, and high-resolution spectroscopy at ESO, SAAO and Mt. John Observatory reveal that HD 123335 (HR 5292) is an eclipsing SB2 consisting of two sharp-lined B-type stars in an eccentric orbit (e = 0.735, Porb = 35.44735 deg). The slowest rotating component (Prot = 61.46 deg) is a chemically peculiar (CP) star of the type He-weak SrTi.
