I don't know how to explain this exactly. I love the looks of larger size pocket watches from the late 1800's on up to the 40's. I have a Hampden from 1915 I believe. The question is what decade and brands started to make pocket watches that were not real delicate? I am looking to add something to my small collection which hold up better in more extreme temperatures, yet still retain a more vintage look. (no steam punk for me). Thanks much in advance for all advice.
