Martin challenged Welch boxer, until then undefeated (27-0) Dai Dower for the EBU's flyweight title on Monday, 3 October 1955 at the ice rink in Nottingham, England. The then 24 year old Martin won the championship by knocking Dower out in round twelve of a scheduled 15 rounder contest.^[2] Martin won the contest with a devastating body attack, producing a number of knockdowns (and ultimately, a knock-out) with hard punches to Dower's body.^[3] Martin successfully defended that title three times until losing it on his fourth defense, beaten by Finnish fighter Risto Luukkonen on Friday, September 4, 1959 in Helsinki, Finland, by a fifteen rounds decision.^[4]

In the midst of his reign as European champion, the Spaniard traveled to Argentina to face world flyweight champion, International Boxing Hall of Fame member Pascual Perez. Perez and Martin duly met on Saturday, December 7, 1957 at the Club Atletico Boca Juniors in Buenos Aires. Perez dominated and stopped Martin in round three to retain the world title.^[5]
