I believe TJ is using Acetimer watch winder cases. They made a few different models in various sizes, number of winder pairs & wood finishes. I have a few of them myself, but unfortunately Acetimer's website went AWOL several years ago & I have not seen any for sale since then.
They really are beautiful cases & the winders are quiet & work well, but their motors tend to fail after 10 or 12 years. In fact, I have been looking for replacement motors for 1 of my cases, but none of the motors I have received have been the correct type. To date, I have not found anything similar to the Acetimer, especially for the prices they originally sold for.
