This piece is very high quality, as would be expected from Haas Neveux, the gilt highlighting of the dial is a particularly attractive feature. It is unusual for a complicated watch to achieve the timekeeping standard of a First Class Chronometer. This is because added complications can have an adverse effect on timekeeping and are therefore rarely submitted for Observatory trial, thus this watch is a rarity, being both high precision and complicated.
