The overwhelming nod for the charter at a weekend referendum raised much optimism for democratic changes in a country long regarded by the West as a pariah state.
The new supreme law protects against all forms of violence and torture and guarantees freedom of expression. But observers say there is little in it that directly affects the way elections are run.
"The constitution does very little to affect electoral conditions," said Zimbabwean legal and political analyst Derek Matyszak.
"If people are thinking the new constitution is going to create conditions for free and fair elections they are going to be very disappointed."
The scars of election chaos are still fresh in Zimbabwe.
Disputed 2008 polls claimed nearly 200 lives and forced President Robert Mugabe and Prime Minister Morgan Tsvangirai into a regionally-brokered power-sharing government to prevent a full blown conflict.
With a major hurdle toward fresh polls cleared by Saturday's vote, Zimbabweans are expected to return to the ballot box later this year.
The adoption of the new text, which curtails the president's powers and sets a limit of two five-year terms, left both leaders of the compromise government beaming.
"That's the type of constitution we want," Mugabe, who has been in power since 1980, told Zimbabwean state media in Rome where he was attending Pope Francis's inaugural mass.
His rival Tsvangirai said the new supreme law "sets in motion a new and democratic paradigm for the country".
Political scientist at the University of Zimbabwe Charity Manyeruke said that the draft did give Zimbabweans a new impetus to respect laws despite little change in the way elections are carried out.
"What the draft constitution does is to give confidence … new energy, new commitment to follow the rule of law, to follow the dictates of the constitution in the conduct of the elections."
Confident of a peaceful vote, she said: "People are tired of violence."
The constitution dictates that the security sector, which is currently staffed with mainly Mugabe's sympathisers, must remain impartial.
But without provisions to enforce this, questions have been raised.
"There is no doubt that without the proper security sector reforms the forthcoming plebiscite would not be free, fair and credible," said an editorial in NewsDay on Wednesday.
The paper said that if Mugabe "is sincere about his persistent calls for peace, then he should spearhead the chlorination of the security sector".
This had been acknowledged by the Southern African Development Community, the curator of the coalition government, as needing "urgent attention".
The referendum weekend saw police raids and the arrest of Tsvangirai aides and his party's attorney. There were also isolated violent incidents against both political sides in the vote run-up.
Repeated calls by Mugabe and Tsvangirai to shun violence bring hope that "we are likely to have a credible election", said Joseph Kurebga, a lecturer at the University of Zimbabwe.
While politicians up their rhetoric around peace, there is a resurgence of intra-party violence as members jostle for spots in party primaries, said Thabani Nyoni, a rights campaigner in Bulawayo.
Such tensions could escalate across rival parties, he said.
"All those are clear signs that the ghost of violence of 2008 could repeat itself," said Nyoni of Radio Dialogue, a civil society organisation.
University of Johannesburg professor of development studies David Moore said levels of violence will likely escalate in the run up to the high-stakes elections.
"But I don't think they will be as high as in 2008 because that was a catastrophe," he said.
The election is likely to be close amid growing disillusionment with Tsvangirai's Movement for Democratic Change.
The party "will have to work as hard as [US President Barack] Obama did against the Republicans" to remain competitive, said Moore. – Sapa-AFP
