The replica IW371618 brings one of the most recognizable Portugieser silhouettes to your wrist without the original's price tag. It pairs the clean, vertical bi-compax dial with a comfortable 41 mm case, so it works as easily with a suit as it does with jeans. If you want the look of a classic IWC-style chronograph in a daily-wear package, this first copy reference is built for exactly that.

Materials and Specifications

The case measures roughly 41 mm across and about 13 mm thick, matching the proportions of the original reference, and it is finished with alternating brushed and polished surfaces. Inside sits an automatic chronograph movement running at 28,800 vibrations per hour with a power reserve in the 44 to 46 hour range, driven by a pusher layout that starts, stops and resets cleanly. The dial uses applied markers rather than printed ones, and the strap is lined for comfort during longer wear. Everything is assembled and quality-checked before dispatch.

Replica IWC IW371618 V8: A Buyer's Checklist

Is the replica IW371618 comfortable enough for daily wear?

Yes. The 41 mm case and gently curved lugs sit close to the wrist, and the leather strap softens quickly, so it wears well under a shirt cuff or with casual clothing.

How faithful is this 1:1 replica to the original Portugieser chronograph?

Case dimensions, dial layout, hand shapes and crystal profile follow the original closely. The movement is a reliable automatic chronograph rather than the manufacturer's in-house caliber, which is the main difference.

What should I check when the watch arrives?

Confirm the chronograph pushers start, stop and reset correctly, check that both subdials align at zero, and inspect the crystal and strap stitching. Report any issue to support right away.
