I recently bought the above camera with full intent on using it underwater.
I can’t seem to find a dive case for it or any clear answer online if there even is an underwater dive case for it?
Please, can someone clear this up for me/us?
I do not believe there is an underwater diving case for the Z1.

the TW-1 is for the V. The TW-2 is for the X. You can confirm the supported models on the link above.
The TH-3 does fit the Z1. However, that case IS NOT WATERPROOF. It is water resistant. Water may get into the case if you submerge the case.
