A wristwatch stand using a captive 3mm nut and 12-14mm screw that allows for positional adjustment of the watch while resting on the stand.  This works especially well if you have a mechanical watch and want to adjust the stand's position for optimal at-rest timing adjustment.  For example one watch I have slightly gains time while worn through the day but if I rest it overnight with 12 o-clock up then it loses just as much as it gained during the day, resulting in approximately +/- 0 accuracy.  Also consider if you have a wristwatch that recharges with exposure to sun, print this in PETG then position your watch for that perfect sun exposure.  Happy making!
