Hello all

Recently inherited this family Rolex, so am trying to find out a few details. Please feel free to correct what little info. I have at present (word of mouth) plus magnifying glass.
If you can add to this please do so.

Ladies 9ct Pink gold Rolex with expanding braclet (1920/30's era?). The others of this era I have seen didn't have the seperate seconds dial at the bottom, so not sure on date.
On the expanding links it has PATENT 197008 REGENT MK11C? 9CIE (9ctC?). Sorry can't be more accurate - eyesight fades with old age and small magnifying glass

Thanks for any help in advance, rough idea of value is welcome but not important as we have ni intention of selling it.
