The IW371424 is the stainless steel Portugieser Chronograph that turned a two-register dial into a modern classic, and replicas now range from thin quartz copies to builds that are hard to separate from the original at arm's length. Our first pick is the automatic version with a domed sapphire crystal, a correctly proportioned 41 mm case, and crisp printed numerals. The other options below are variations on that theme.
IWC IW371424 Replica Guide: How to Judge Quality Before You Buy
Key Features
- 41 mm polished stainless steel case with slim bezel and curved lugs
- Two-register dial: 30-minute counter at 12, running seconds at 6
- Silver-plated, black, or deep blue dial with high-contrast printed numerals
- Domed sapphire crystal with anti-reflective coating inside
- Automatic chronograph movement, 44-hour power reserve, sweeping seconds
- Alligator-pattern leather strap with dial-matched stitching, or steel bracelet
- Screw-down caseback with everyday splash resistance
- Deployant clasp or pin buckle in polished and brushed steel
Case parts are machined from 316L stainless steel, then polished on the bezel and brushed along the flanks; sharp transitions are the first thing low-grade copies get wrong. The dial is matte or sunray-finished depending on the version, with faceted hands and heat-blued or polished finishes on the higher tiers. Expect roughly 41 mm across, about 13 mm thick, and a 20 mm lug width, so most aftermarket straps fit. Automatic versions run a 7750-derived chronograph movement at 28,800 vibrations per hour; quartz alternatives are thinner but lose the pusher feel.
Which version is worth picking first?
The automatic clone with a sapphire crystal and a screw-down caseback. It is the only tier that gets the dial spacing, crown position, and weight distribution close enough to wear daily.
Replica IW371424 vs Original: A Comprehensive Comparison
What do the quartz options give up?
Thickness, mostly, along with the sweeping chronograph hand and the mechanical pusher feel. Dial printing and strap hardware are usually the first places the shortcuts show.
How does it wear compared with the original?
On a 6.5 to 7.5 inch wrist the 41 mm case sits flat and the short lugs stop it overhanging. A good build feels dense and settled; a poor one feels top-heavy and rattles when shaken.
Orders ship in plain, discreet packaging with tracking, usually within a few days of payment clearing. Inspect the watch before removing the crystal film, and confirm the chronograph resets cleanly to zero. If the movement runs badly or the crystal arrives scratched, a straightforward exchange should be part of the deal, so get that confirmed in writing before you buy.
