The replica IW371756 is a close visual match to the IWC Portugieser Chronograph, built around a 41 mm stainless steel case, a domed sapphire crystal, and a working twin-register chronograph. If you like the clean, legible Portugieser look — feuille hands, slim bezel, large applied numerals — this reference gives you that silhouette without the original's price tag. Below is a plain rundown of what the watch does, what it is made of, and how ordering works.

- Domed sapphire crystal with anti-reflective coating on the underside
- Automatic chronograph movement with central seconds and a quick-set date
- Rated for everyday water resistance against splashes and rain
- Leather strap with contrast stitching and a signed pin buckle
- Adjustable strap length fits wrists from roughly 15 cm to 20 cm
Materials are where a good replica separates itself from a cheap one. The case is solid 316L stainless steel, roughly 41 mm across and about 13 mm thick, with polished flanks and a brushed bezel. The crystal is real sapphire with an inner anti-reflective coating, so the dial stays readable in bright light and the glass resists the desk-knock scratches that haze mineral glass. Applied metal numerals, printed subdial rings, and a discreet date window finish the dial, and the stitched leather strap is fitted with a steel pin buckle that matches the case.
Orders are packed in a protective travel box and ship within one business day, with tracked and insured delivery available to most destinations. If the watch is not what you expected, unopened pieces can be returned within the stated return window for a refund or exchange, and our support team answers sizing and strap questions before and after purchase.
Does the chronograph actually work?
Yes. The pushers start, stop, and reset the central chronograph seconds and the 30-minute totalizer, and they feel crisp rather than mushy. The subdial at 6 o'clock is a running small seconds hand, not a decorative print.
How close is it to the original IW371756?
Externally it is very close: same case diameter, dial proportions, hand shape, and strap style. Differences show in movement finishing and caseback engraving detail, which is why it is sold as a replica.
Can I change the strap?
Yes. The lugs take standard-width spring bars, so most aftermarket leather, rubber, or steel straps in the matching size will fit without modification. Swapping takes a minute with a spring bar tool.
