Me and a friend bought 2 racing models some months ago and both watches came with this box from Omega.
The outer carton boxes also have printed the order, the ref. number of the watches and the WL Date.
By the way both watches were models of 2019 & 2020 as well.
You may are right regarding the first models of 2012 - 2016
Mine is 12/2020 and has the same ref. Number
