Comparing a replica IW371785 to the genuine IWC Portofino Chronograph comes down to three visible things: how the case edges catch the light, how crisp the dial printing reads at arm's length, and how the chronograph pushers feel under your thumb. A good first copy gets all three right; a weak one fails at least one. Here is what to check before you buy, and which version we would shortlist first.
Key Features
- 39 mm polished stainless steel case matched to the original Portofino Chronograph proportions
- Silver-plated dial with twin chronograph sub-dials, applied baton indices and a correctly placed date aperture
- Anti-reflective coated crystal with a clean, undistorted edge at shallow angles
- Chronograph pushers with a firm, defined click instead of a mushy press
- Genuine leather strap with tight, evenly spaced stitching and quick-release spring bars
- Automatic or quartz movement options depending on the tier you choose
- Caseback engraving and reference formatting consistent with the original layout
- Water resistance rated for handwashing and rain, not swimming
Materials and Specifications
The case is 316L stainless steel with brushed flanks and a polished bezel, which is where most replicas cut corners — look for an even transition between the two finishes. The dial is brass with a silver-plated finish, applied indices set at consistent heights, and polished hands with a light lume fill. Crystal is sapphire-coated mineral on entry tiers and true sapphire higher up. The strap is calf leather on a signed pin buckle, and the movement is either a quartz caliber or an automatic with a chronograph module, so check which tier you are ordering.
How Close Is a Replica IW371785 to the Original?
In daily wear, a well-made replica is very close: same case diameter, same sub-dial layout, same wrist presence. The gaps appear under magnification — slightly softer dial print, marginally different pusher travel, and less refined hand-finishing on the caseback.
Which Version Should You Pick First?
Start with the automatic tier if you want the sweeping chronograph hand and correct pusher feel, since that is the difference you notice most. The quartz version is the better pick if you want a grab-and-go watch and rarely use the chronograph.

Will the Strap Fit Standard IWC Bands?
Yes — the lugs follow the original spacing, so most aftermarket straps for the Portofino Chronograph fit without modification. Quick-release spring bars make swaps tool-free.
