The replica IW371478 recreates the IWC Portugieser Chronograph Edition "150 Years" — a slim stainless steel chronograph with a deep blue lacquered dial and a balanced two-register layout. It is the reference to look at if you want that Portuguese dress-sport silhouette on your wrist without chasing a limited-run original. Everything below describes what the watch actually is, so you can decide before it ships.

Materials and Specifications
The case measures roughly 41 mm across and about 13 mm thick, which keeps it in dress-watch territory while staying legible on a medium-to-large wrist. Lug width is 20 mm, so most aftermarket straps fit without modification. The dial is the centerpiece: a glossy blue lacquer that shifts from navy to near-black depending on the light, framed by polished applied numerals and slim leaf hands. Pushers sit at 2 and 4 o'clock and operate a real chronograph function. Inside, an automatic chronograph movement drives the central seconds and the 30-minute totalizer, and the sapphire caseback shows a decorated rotor. The leather strap is lined for comfort, and the buckle is a plain steel pin, easy to swap for mesh or fabric if you want a sportier look.
Shipping and Returns
Orders are packed discreetly and dispatched within one business day, with free tracked shipping and a tracking number sent as soon as the parcel moves. If the fit or finish is not what you expected, you have a 30-day window to return the watch unworn in its original packaging for a refund or exchange. Reach out to support first and you will get return instructions the same day.
Does the chronograph function actually work?
Yes. The pushers start, stop and reset a working central chronograph seconds hand, with elapsed minutes accumulating in the counter at 12 o'clock.
What size wrist suits the 41 mm case?
It wears best on wrists from about 6.5 to 7.75 inches. Smaller wrists can still carry it thanks to the short, curved lugs, which keep the watch sitting close to the arm.
How should I care for it?
Wipe the case with a soft cloth, keep it away from steam and hot water, and avoid operating the pushers while the watch is wet. A strap change every few months keeps the leather fresh and the watch looking sharp.
