The club celebrates the milestone this weekend and commissioned a panel to select a greatest XV, plus reserves, over that period.
Understandably, the team is built around hard-nosed flanker Don Clark, who played two tests against Australia in 1964.
Clark, who also played 79 games for Otago between 1962 and 1968, is the Cromwell club's only genuine All Black.
Clark is joined in the Cromwell dream team by brothers Tony, Colin and Ritchie. Tony is named at first five and the other two are in the reserves.
The Colling name also appears. Don Colling, who played 80 games for Otago between 1968 and 1977, is at centre, and John Colling is on the bench. John represented other clubs while making 65 appearances for Otago, but he played for Cromwell in other seasons.
Trevor Leyser, one of the locks, has been instrumental in arranging the 125th celebrations and is the club's longest-serving living member.
Cromwell has a dinner on Saturday night and will be naming a second dream team, consisting of the best players of the past 25 years.
Two of the leading candidates for that XV are expected to be jubilee chairman John Fitzgerald, who captained the champion Cromwell team in 2007, and former All Black prop Joe McDonnell, who played for the club before heading to Dunedin.
