On 2 May 2018, Platense was directly promoted to the second division after winning the Primera B Metropolitana title in a victory over club Estudiantes de Caseros.

In 2021, Platense would make their return to the Primera División for the first time in 22 years after defeating Estudiantes de Río Cuarto on penalties to earn promotion.

The club's main claim to fame during these lean years is the success of Momo and David Trezeguet, who had debuted at Platense but after playing only 5 matches in Argentine Primera División was transferred to AS Monaco.

The club is also cited in Bioy Casares's book El Sueño de los héroes ("Dream of Heroes" ISBN 0-7043-2634-5).

The model released in 1997 and made by Puma caused great controversy among their fans due to its similarity with the Argentinos Juniors (which had a fierce rivalry with Platense) kit.

[8][9] Along their history, Platense has also introduced some variants to the brown and white colors, such as a vertical stripes shirt worn in 1922 (which had a commemorative edition in 2012).
