And see what it says ??
I doubt it could have the OP XI because this movement was installed in the Pam 61 OOR series and the OOR were produced in 2003 ( equal to the F series ) and in the Pam 118 in the E series
Ps, I'm curious to know how you know your 61 is a late D series .... by its millesimation ? do you know they're not produced in order ? and the #1000 can be build before the #0211
