longest world champion reign ever cc for answer

[Tito BHB]

Longest reign should really be measured in title defences..

..not years.

Whom would that be?

Some dudes are fighting 4/5 times a year whilst other only fight 3 times a year if that..

you make a good point, but those that reign in years with few defences usually either get stripped or noone wants to no cos theyr jessy's lol.
