So today, I spend a little time turning this:
into this:
I used the movement and second hand form the old watch and transplanted them into a new housing and face I got from Fleabay. At some point, I might get a second face to cut a larger window and make the day wheel work again, but that will be a project for another day. The trickiest part was trimming down a new stem for the crown. The old one was about 1/2mm too short and the replacements come in at 20mm, which is about 5mm too long.
Originally, there was a white second hand to match the other two, but gravity made it dissapear. Honestly, I think the red adds a little more contrast so I considder that a happy little accident.
