ALT1-P Black


The ALT1-P is designed for those who demand both accuracy and clarity. The clear Super-LumiNova® C3 hands and dial numbers make it a popular choice with aviation professionals. Like the Bremont ALT1-Z, the case has an integrated internally rotating bezel. Operated by a crown situated at 8H, it effortlessly measures the time of trips. The modified COSC tested Valjoux movement is finished to the highest possible standards.
