We present near-infrared ( JK _ { s } ) time series data of the Large Magellanic Cloud ( LMC ) cluster Reticulum .
The observing strategy and data reduction ( DAOPHOTII/ALLFRAME ) allowed us to reach a photometry accuracy of the order of 0.02 mag at limiting magnitudes typical of RR Lyrae stars .
We are interested in Reticulum , since it hosts a sizable sample of RR Lyrae ( 32 ) , and therefore the use of the K -band Period-Luminosity-Metallicity ( PLZ _ { K } ) relation will allow us to supply an accurate LMC distance evaluation .
The main advantages in using this method is that it is marginally affected by off-ZAHB evolutionary effects and by reddening corrections .
As a preliminary but robust result we find a true distance in good agreement with the LMC Cepheid distance scale , i.e . \mu = 18.47 \pm 0.07 mag .
