Looks nice,

Had a couple questions.

Do the bezel screws go into the plastic or time certs? What are they made of?

The Metal cap is Stainless as is what it's screwed into for the battery compartment? We had a few problems with stainless to stainless. Had to use a lube so it wouldn't gaul. Any option of a lubricating plating on the threads? Not on the sealing surface though.

Any option of having them filled at the factory with mineral oil?
The bezel screws go into the plastic, but are around 1" deep - so there's lots of thread. Not only that, but the o-ring sealing the Lens is much larger than we've used in the past, allowing more surface area for seal.

The thread on the battery caps is sufficiently coarse so that galling should not be an issue. In 8 months of mixed Fresh and Salt water diving by our guys, there have been zero issues with this. No lube, no corrosion, nothing.

As for Mineral Oil - we never have done this, for a wide variety of reasons - but should someone desire to do so, it would be a LOT easier on this set than any of our previous versions.
