Its *Probably* a 32.768kHz crystal, as very few things except low frequency time-keeping crystals are ever in that particular type and size of package, and 32.768kHz is by far the commonest time-keeping crystal frequency.
However as long as the crystal's metal can is still intact, any breakdown of any coating on it or corrosion of the outside of the can is very unlikely to stop it working as the can is hermetically sealed to protect the tuning fork crystal inside it.
I see green powdery residue nearby on the PCB so odds are you've got one or more broken tracks or vias due to corrosion.
