no you cannot.
only a stem for the eta 28xx series, that means also for the 2892 and 2892A2.
this movement is the basic movement for the soprod module.
so... the stems have a 0,9mm thread for the crown.
that means you have to buy a t-crown for a 0,9mm stem,
or a t-crown for a 1,2mm stem and you have to use a 1,2mm thread adapter-stem with a inner thread of 0,9mm for the 28xx serie stem.
