Wifi Lorar V2.1 - Crystal Specs

I’m trying to work out the amount of error on the clock timing for this board. My understanding is that the onboard RTC is driven from an external SMD 32 Mhz crystal which I can see from the schematics (connected into 32K_XP).

I’m looking for the frequency stability figure of this crystal - this doesn’t seem to be in the documentation.
