Jake Paul might be the best brother of all time ... 'cause El Gallo hooked Logan up with an extravagant Christmas present this year -- an Audemars Piguet watch!!
The WWE Superstar shared the kind gesture on his Instagram page this week ... showing off what appears to be a Royal Oak Selfwinding Chronograph timepiece, which comes with an eye-popping, tens-of-thousands-of-dollars price tag.
The Paul Bros enjoyed their holiday on the lake with all their loved ones .
