This was indeed an issue in previous versions that got fixed (see thread and solution here).
I have tried to reproduce the issue and it is indeed happening to me too. Whatever custom texture I apply to the band of the watch just disappears in live mode, while textures for other parts of the watch stays correctly.
My specs: Windows 11, 11th Gen Intel(R) Core™ i7-11700F @ 2.50GHz (2.50 GHz), NVidia RTX 3060, 16 GB RAM
