Manual winders tend to come in the marine/deck watch style, and satisfy your criteria in all but the size you would like, mostly 42mm, although the Steinhart is 44mm. I have to say that I'm really enjoying my Archimede that I bought from SC several months ago. Perhaps the Stowa Partitio may fit the bill, comes in black too. https://www.stowa.de/lshop,showdetai...partition,.htm
