19mm Constellation Case Opener and Watch Holder to 3D-Print

kaplan · Mar 24, 2021

I had a Constellation that just didn't want to open, one challenge is to latch opener tools to the watch, a secondary challenge is to hold the watch without damaging it and also not hurting yourself, printed the first version of this design and managed to open it without scratching the caseback - but none of the fins of the 3d-printed tool made it 😀

This below is the second version, the holders height might be off again

First version of the opener had 2mm width fins, this one has 2.4mm ones, it should be more sturdy - didn't perfect the dimensions yet

One of our members made and sold one for Speedmaster models.

A 3D-printed tool can sometimes / often be enough to open a watch, especially connies as they’re rarely as stuck as a speedy can be. Connie casebacks have different designs, so what fits one won’t necessarily fits another. My brass connie opener to the right:

I recently bought a 3D-printer to play with - I have great fun with it, for example does the speedy opener now come with a stand 😀

Wow, that brass tool does look good 😁

Mine in action - the lug holder could be narrower I guess
