These three have not been getting any wrist time in the last few months. I think its about time to let them go and put the money towards another 6R15.
With the introduction of the 6R15 movement a year ago, I find that the 7Sxx movement is no longer attractive to me because it does not hack nor handwind. 6R15 is the bare minimum movement that I now prefer.
As for the pocket watch, I find that it is not so practical to use it today. I have so many things in my pocket that I can’t afford to squeeze in a pocket watch. Besides, it is quite heavy despite being a quartz. I did enjoyed making lanyards for it though.
