·When I recently traded my 1861 on a 3861, my AD told me the kit added at least $800 to it's trade value. It was a full kit, including an unworn bracelet with all links (I wore the 1861 on a deployant strap) with all the boxes and sleeves including the hang tag. It never made it into the pre-owned case, after the prerequisite testing, it was sold with a phone call. Definitely worth keeping.
Thanks for sharing your experience. 😀
