It is a very nice watch the 5120, but ideally I want a second hand on my watch.
That 5119 is sits really nice on your wrist and with the blue strap it looks less formal. In a perfect world I would look at the 5119 and 3919 side by side, but there is no jeweller in the area that has a used 3919, hence my questions on this forum.
I would love to hear from some 3919 owners, for reference my other watches are 40mm
