This marvel of precision and reliability ensures smooth operation and accurate timekeeping, with a 42-hour power reserve that makes daily winding unnecessary. The Portofino Automatic 37's perfect size (37 mm diameter, 9 mm height) and comfortable wear make it an ideal choice for everyday wear. Paired with a high-quality leather strap, this watch exudes sophistication and is suitable for light splashes and rain. Although not designed for diving adventures, its elegant design, reliable movement, and comfortable fit make it a standout piece in any collection.
