Portofino Steel Silver Dial 37mm

The IWC Portofino (ref. IW458601) refines the collection’s signature elegance into a slimmer 37mm format, making it an ideal choice for those drawn to understated design in a versatile size. Its silver dial, understated yet luminous, is framed by a polished stainless steel case that highlights the model’s classic appeal.

Introduced in 2022, the Portofino Automatic 37 is powered by the IWC calibre 32111 – a self-winding movement crafted in-house and visible through the sapphire caseback. With an extended 120-hour power reserve, the calibre offers a compelling blend of long autonomy and slim architecture. The watch is water-resistant to 50m, making it well-suited to everyday wear while preserving a refined profile.

Balancing a mid-century aesthetic with contemporary watchmaking substance, the IW458601 enhances the Portofino line’s reputation for pared-back luxury. Its 37mm diameter ensures comfort across a broad range of wrist sizes – a configuration that continues to attract collectors seeking daily simplicity without mechanical compromise.
