I thought the DS1302 was being obsoleted. It IS easy to use, tho.

I've grown fond of the Xicor X1226 because it has such a tiny
background current, has an onboard 512-byte EEROM, and
has a timekeeping compensator (trimmer) of +/1 100ppm, a VERY
helpful feature when you need to have an accurate clock.
