Ms Linda - an Over The River & Through The Woods suggestion: I
enjoy Agatha Christie’s super-sleuth Hercule Poirot. Nurses
(trench soldiers, certainly not management types) in these 1920’s
period pieces almost always have such a brooch/watch. When I was
in nursing school there were a few British nursing periodicals
available in the library. This type of watch appears so useful,
maybe it is still available!?
