sorry, but too much of the information here is wrong, so have to react.
a) it is not "the last generation before the new equipment B02 cosmonaut", but a "Lemania Cossie", produced between 1992 and 2001, this one probably towrds the end of this period.
b) it is not a flyback chronograph
c) not really relevant here, but the Breguet Type XX was not Lemania-based, but had a Valjoux 222 (with flyback
)nice watch though, GLWS
Edit: thanks for the pm, most errors gone now, just the Lemania Breguet Type XX ?
Edit 2: seller wants me to mention that the current Breguet Type XX reincarnation has a Lemania movement - automatic and in no way similar to the 1873 in the Cosmonaute, but a Lemania.
