Clock widget with the least RAM footprint

Need a recommendation of a clock widget that is very lean in RAM usage. This is for my Huawei Y300 which only has 512MB of RAM (actually, only 393MB of RAM for user as reported by the OS, and usually leaves around 50-70MB free after boot up). I had one that I use on my other Android devices (all having at least 1GB of RAM), but apparently it can take up to 30+MB of RAM. That is not noticeable on my other devices, but obviously is an issue on this Y300. Trying to browse for a clock widget in the Play store is like browsing for a short hay in a haystack. Any recommendations?
