Posted on by

This year, a perpetual calendar model joins the Ingenieur range of timepieces by IWC Schaffhausen. Technically, this model boasts similar functions of the IWC Portugieser Perpetual Calendar Digital Date-Month Edition “75th Anniversary” that was launched early this year at SIHH. But when we talk about it external specifications, this new timepiece is sportier and rugged thanks to its Ingenieur roots.
