<p>The age-metallicity relation is a fundamental observational tool for constraining the chemical evolution of the Galactic disc in time. In this work we analyse the observational properties of this relation using binary stars consisting of a main sequence star -from which we can derive the metallicity- and a white dwarf -from which we can derive the total age of the system. Our sample consists of 49 wide WDMS binaries, identified within the Sloan Digital Sky Survey, that evolved avoiding mass transfer episodes. The 49 objects were observed with the VLT/X-Shooter and GTC/Osiris+EMIR telescopes/instruments.</p>
