IWC Portofino IW544801 Moonphase Men’s Watch

The IWC Portofino IW544801 is an exceptional men’s dress watch from the IWC Vintage Collection, created to celebrate the heritage of IWC Schaffhausen. Combining a refined 46mm stainless steel case with a sophisticated matte black dial, white Roman numerals, moonphase display and black alligator-style leather strap, this Portofino offers an elegant interpretation of classic Swiss watchmaking.

IWC Portofino IW544801 Vintage Collection

The IWC Portofino IW544801 belongs to the Portofino Vintage Collection and is associated with IWC’s 140th-anniversary collection. The reference 5448 was offered in different precious-metal and stainless-steel versions, with IW544801 being the stainless-steel version paired with a black alligator leather strap.

Elegant Black Roman Numeral Dial

The watch features a refined matte black dial with large white painted Roman numeral hour markers. The clean outer minute track and elegant hands provide a classic dress-watch appearance. The contrasting white numerals against the black dial create excellent visual definition while maintaining the understated character of the Portofino collection.

Moonphase Display at 12 O’clock

One of the defining features of the IWC Portofino IW544801 is its moonphase display positioned at 12 o’clock. The moonphase complication tracks the lunar cycle and adds an unmistakable touch of traditional horology to the watch. The moonphase mechanism is designed for remarkable accuracy, with documented specifications noting a deviation of approximately one day every 122 years.

Small Seconds at 6 O’clock

A dedicated small-seconds sub-dial is positioned at 6 o’clock, balancing the moonphase display at the top of the dial. This symmetrical arrangement gives the watch its distinctive Portofino 5448 appearance while providing a useful indication of running seconds.

IWC Calibre 98800 Hand-Wound Movement

The IWC Portofino IW544801 is powered by the IWC Calibre 98800, a mechanical hand-wound movement. It operates at 18,000 vibrations per hour, contains 18 jewels and provides an approximate 46-hour power reserve when fully wound. Unlike an automatic movement, the watch requires manual winding through the crown.

46mm Stainless Steel Case

The stainless steel case measures approximately 46mm in diameter and around 11mm in height. Its polished construction gives the watch a refined appearance, while the large case size provides a strong presence on the wrist. The sapphire crystal caseback allows the mechanical movement to be appreciated on compatible examples.

Sapphire Crystal & 30m Water Resistance

The watch uses an arched-edge sapphire crystal with anti-reflective treatment, providing excellent scratch resistance. The documented water-resistance rating is 3 bar / 30 metres, appropriate for everyday splash resistance but not intended for swimming or diving.

Black Alligator Leather Strap

The stainless steel case is paired with a black alligator/crocodile leather strap and a stainless steel buckle. The dark strap complements the black dial and creates a classic formal appearance suitable for business attire, evening wear and special occasions.
