The first one is not what I would call a 'Molnija frankenwatch'. Rather it is a modern wristwatch powered by a Soviet-era Molnija movement. The second one uses a Molnija pocket watch crown as well as [post-Soviet movement (regulatuer modified), but again the case looks new rather than modified.
I see nothing in either of these which attempts to pass them off as genuine Soviet vintage pieces. So my only (slight) concern would be in the use of a large pocket watch movement with no shockproofing in a wristwatch where it may be subject to shocks beyond what it was designed for. Wear it with care and it should be fine.
