Talk of the Latics' first appearance in one of the showpiece days in the English football calendar has inevitably included discussion about a relegation fight they now look certain to lose.
Yet it is an undeniable truth that a win will have an effect on Wigan that will last far longer than what league they end up playing in next season.
For Jim Montgomery, Bobby Stokes and Lawrie Sanchez are part of the very fabric of football in this country, and will continue to be so no matter what strife Sunderland, Southampton and, most tellingly of all, Wimbledon find themselves in at any given moment.
It is these names the Latics will join if they can find a way to overcome Manchester City at Wembley.
And the impact of such a success is not lost on Martinez.
"You have to dream and the bigger the dream the bigger the achievement," he said. "Winning the FA Cup would be there forever.
"Just arriving in the final is a photographic moment in the history of our football club. Winning a major trophy would take our club to a different level.
"We are all well aware what this could mean. There are a billion people watching this game.
"It is one of those key moments that help develop awareness."
