Curious Seachero w Broad Arrow

This just sold in a small regional auction in the US for $1150 all-in ($1k+15%). I know nothing about it, was interested at a lower price, but am curious what others have to say. Presumably it's a 2990-1? There's a very similar model here, sold awhile back; I'd hesitated because the Seamaster lacks the coat hanger S, though the linked watch also has the rounded S, too. Anyway, hope someone here got it.

I had 5 pairs of those hands in gold. I think they either used the arrow or Dauphine luminous hands

Well, whoever got it has now posted it to ebay with the same 2 pictures as above with a starting bid of $2k.

When I bought mine. I paid $212 for it. Had a horrible redial with ham radio call numbers printed on it

No buyers, so broke it up and sold it for parts. Dauphine hand model.
