Continuous, smooth sweep motion removes any Ticking noise1/4" Maximum dial Thickness; 5/8" Total Hand shaft LengthAuthentic Seiko brand clock movement, marked as Skip (Seiko precision ) on the backsideIncludes a pair of Black spade 2-1/2" Hour and minutes hands, a Red 2-3/4" Second hand, and mounting hardware
It should be fine as long as the arms are weighted such that the center of mass is lined up with the hole the clock hardware goes through (within reason, obviously). He likely got a "high torque" one, too.
And on his other reddit page he linked to his etsy, which says he used aluminum for the arms.
You can buy a small one. We usually use SwimOutlet but if you know any swimsuit sellers at swim meets, you can ask them if they would be able to buy something for you and most of the time they will.
Or build your own (not attempted by me)!
