You could try Maxim's MAX6902. It is an SPI compatible RTC, with timekeeping current consumption of 400nA at 2V. It also operates from 2v -> 5.5V. However it comes in a TDFN form factor (3mm x 3mm x 0.8mm). Accidently flick it with the tweezers and it's gone. However I understand that Maxim's delivery schedules leave something to be desired. Sample deliveries are ok though. Today I received a MAX1811 Li+ charger ic about a week after I requested a sample.
