IWC Portugieser Chronograph Steel — Silver-Plated Dial Steel Bracelet | Ref. IW371617

The Portugieser Chronograph on bracelet is a configuration that asks the collection's classically leather-strap-oriented design language to adapt — and it does so with surprising success. The 41.0 mm stainless steel case, at a notably slender 13.0 mm, achieves a wrist presence that reads closer to a formal dress chronograph than to a sports instrument, a character reinforced by the silver-plated dial's restrained silver-white field and the collection's trademark slender registers and applied hour markers. The see-through sapphire case back offers an unobstructed view of calibre 69355 in motion.

Calibre 69355 is IWC's in-house automatic chronograph movement featuring column-wheel regulation — the mechanism that defines the quality feel of the pusher engagement and the precision of start, stop, and reset operations. With approximately 46 hours of power reserve and indications covering hours, minutes, small seconds, and chronograph, it provides a technically complete specification appropriate for a watch at this price tier. The lateral clutch chronograph architecture minimises perturbation to the running train during chronograph activation, a refinement that preserves long-term movement accuracy.

The integrated stainless steel bracelet broadens the wearing occasion range of this Portugieser variant, rendering it equally credible as an office chronograph or a weekend instrument. The combination of silver-plated dial and steel bracelet creates a cool, monochromatic palette that emphasises form over material ostentation — a choice that will age gracefully and resist the tyranny of changing fashion trends. At 7,565 USD, this reference represents one of the more attainable entry points into in-house IWC chronograph movements. Water resistance to 3 bar is the standard specification.
