®
reserve of approximately 42 hours when fully wound. Your Porto-
fino Automatic/Portofino Automatic 37 is protected by a sapphire
glass of hardness grade 9 on Mohs' scale. Your watch is water-
resistant 3 bar. To ensure that this extraordinary watch continues
to perform faultlessly in the future, it is essential to observe a few
important operating instructions.
