This is a 40mm Lemania 5100 chronograph. It is close to new old stock, unpolished, and near-pristine. This is the real Lemania 5100 chronograph with the Lemania-signed dial and movement. You will see the Heuer-version offered with the same case and dial for over $7000, but this is the original Lemania-dial version. The movement was cleaned and the chronograph functions are working perfectly. This watch is very rare. There’s not one negative thing to mention about this Lemania!
