The movement is also numbered if you look carefully.
Unfortunately its inside an H20217-3 case, and should not have lume on the dial or hands, so something is amiss.
It is also missing the 'unadjusted' text, as expected for a chronometre.
So to be fair, the answer to the OP's question is yes - the dial matches the serialised chronometre movement.
Surely a chronometre movement would have "adjusted 5 positions" text although I have read on this forum that this was omitted for the US market to avoid extra customs charges.
Are you saying that no Polerouters have serialized movements unless they are also have "Chronometre" on the dial?

H cases seem to use a different plexi mounting (with wire/tension ring) than S cases, from what i can tell.
I have a stack of H 20217-3 saved in my archive folders.
They are all non-lume on both hands and dial.
E.g. H20217-3 serial 1806842 (close to your 1806892):
Yes I can confirm 100% that mounting is different between S and H case but not only for plexi but also case size and case inner shape is different. You can not switch a S case mouvement 138 ss and its mouvement holder in a H case and vice versa.
Thanks for your example which leans towards your assumption but does not 100% confirm it. Now next question : have you seen any 138ss Chronomètre with steel H case? With steel S case?
given the scarcity of H case vs S case (which percentage btw?) and the extreme scarcity of 138ss chronomètre (1 out of 1000 ?) if we follow your theory that this watch being a franken, someone went into a lot of complexity and hassle to produce a watch that is at the end not much worth more than a regular 138ss... UGs are not in the same price gap as Zenith or Omega when you switch from a regular one to a Chronomètre one.
At least not yet ;-)
