Nicknamed Clockwork by the British for his midfield consistency, as well as the nickname being suggested by his surname, he is often cited as the last of the old-fashioned attacking centre-halves; he was known for his aesthetic and technical style of playing, his heading ability, excellent timing (both in offensive and defensive tasks) and his passing range; particularly his long passing ability.

He then played for Floridsdorfer AC, where he was spotted by former Austrian international Josef Smistik, who moved Ocwirk to centre midfield.

Smistik tried to bring him to his former team, Rapid Wien, but it was rivals FK Austria who won the race for his services and, in 1947, signed him.

In a decade at Austria Vienna, Ocwirk became one of the most prominent players for the club, helping them to win five Austrian League championships and three domestic cups.

[2] By 1953, the stopper centre-back had taken over, so Ocwirk was selected as a wing-half for a Rest-of-the-World team which drew 4–4 with England to celebrate the 90th birthday of the Football Association.

The centre-half scored two goals during the tournament: the one that gave Austria the lead after trailing 3–0 in the memorable quarter-final against hosts Switzerland, and the 3–1 in the third-place match against reigning champions Uruguay.
