The IW371489 is one of the cleanest expressions of the modern Portugieser Chronograph: a slim 41 mm case, a sunburst blue dial, and a vertical two-register layout that keeps the face balanced and easy to read. This 1:1 replica keeps that profile intact, with a working chronograph, a domed sapphire crystal, and finishing that looks right on the wrist. If you want the Portugieser look without the boutique premium, this is the reference to start with.

Materials and Specifications
The case is machined from 316L surgical-grade stainless steel, with polished flanks and a lightly brushed caseback ring for contrast. The crystal is real sapphire rather than mineral glass, so it shrugs off everyday scratches, and the dial is sunray-brushed blue that shifts from deep navy to bright cobalt depending on the light. Lug width is 20 mm and the case measures about 13.5 mm thick, so it slides under a shirt cuff without catching. The automatic chronograph movement runs at 28,800 vibrations per hour and holds a power reserve of roughly 44 hours when fully wound.
Shipping and Returns
Orders leave the workshop within 24 to 48 hours in plain, discreet packaging, with tracking sent as soon as the parcel is on its way. Each watch is checked, regulated, and timed before dispatch, and you get an inspection window after delivery. If the chronograph, winding, or timekeeping is not behaving as it should, contact support for a replacement or a return, and a movement warranty covers defects under normal use.
Is the replica IW371489 suitable for daily wear?
Yes. The steel case, sapphire crystal, and 20 mm strap make it comfortable for everyday use. Just keep it away from swimming and showers because of the 3 bar rating.
How close is it to the original Portugieser Chronograph?
Case dimensions, dial layout, hand shape, and strap are matched closely enough that the difference shows only under close inspection. The movement inside is a replica-grade automatic rather than the original manufacturer's calibre.
What should I check when the watch arrives?
Start the chronograph, let it run a few minutes, and confirm both pushers reset cleanly to zero. Wind it fully, wear it for a day, and check that it keeps time and holds its power reserve overnight.
