Looks like E. oxygona, possibly not a hybrid.

Agreed. Oxygona to me too

Thank you for your ID. Until this day it was under the name of Echinopsis sp.
The flower looks similar but my plant is almost spineless

It is possible for echinopsis eyriesii to have pale pink flowers as well as white. I've seen them with pale pink flowers.

Still, some plants are so hard to get a definite name for because of the variability within species, similarity between species and all the hybrids about.
