Although there are Chronometre rated versions...
: Why is it that the Lemania 1873 is marked as
: "unadjusted". If it was certified
: as a chronometer wasn't it supposed to be
: adjusted for at least 5 position?
It's not a certified Chronometer... Although there are Chronometre rated versions of the Lemania c.187x chronograph, the most famous being the limited edition Speedmaster c.864's, they are very VERY uncommon. Most (99%+watches using this movement (mainly Omega, but I own Bucherer, Tissot, Heuer, TAG-Heuer, and Meylan's that use it) are not submitted for certification.
