Well I do not do office or secretarial work.
Sadly I have been mostly wearing my 17 buck apple watch from shopGoodwill. The alternate is the 32 or so mm black dialed Wakmann. But I am a bit out of the norm. I also like my 42mm Chronostop, which is the one I chose to take to Switzerland last year.
I have been collecting a lot of 20-25 mm watches lately. There are some rather nice examples out there. My goal is to make some new straps for them.
My mother likes 20mm watches, and that is what I grew up with as well -- till I started collecting. Mom also seems to prefer the simplicity of quartz.
Cocktail sub 16mm watches are of little use in this day and age.
Curiously at the Dickens fair rehearsal we were talking about ladies clothing vs the gents. There are some really nice gents bespoke tailors, who will not touch ladies garments. When asked, they replied "Women are hard to fit. They come in many more different sizes and shapes than men do. No two women are alike."
So it is really hard to generalize. I have also noticed women are told what we do and do not like much more often. There are lots of societal pressures what can influence things. If a man gives a women a watch there are expectations. This in turn leads to all sorts of feedback.
Like everything else there are good and bad watches in any size. It often comes down to the individual watch. The smaller vintage Dive watches seem to be selling well in this buyers market. Dive watches are fairly unisex.
I have noticed a lot of actors wearing watches. As pointed out the girls in the Austrailan H2O mermaid show all wear dive watches. Was watching Dr Who the other night and noticed the companion wearing a watch. Could be these are practical for production use. Victorians did not wear wrist watches. Pocket, and lapel watches are used by the Dickens actors. The ubiquitous phones on the other hand...
