We analyse CCD broad band ( U BV ( RI ) _ { C } ) photometric data obtained in the fields of the poorly studied open clusters NGC~2425 and NGC~2635 .
Both clusters are found to be of intermediate age thus increasing the population of open clusters known to be of the age of , or older than , the Hyades .
More explicitly , we find that NGC~2425 is a 2.2 Gyr old cluster , probably of solar metallicity , located at 3.5 kpc from the Sun . NGC~2635 is a Hyades age ( 600 Myr ) cluster located at a distance of 4.0 kpc from the Sun .
Its Colour Magnitude Diagram reveals that it is extremely metal poor for its age and position , thus making it a very interesting object in the context of Galactic Disk chemical evolution models .
