since ML launch its first in house... an automatic chronograph... a big hit, because there are not many in house auto chrono movement.... its more difficult to create than tourbillon.... then we see the mushroom after rain...
we have seen pam, breitling, hublot..... and now tag!
this one dont seem as aesthetic as ML.... the blued column wheel is copied of the ETA special made for longines!
