The IW371618 sits at the centre of the Portugieser chronograph family, and this 1:1 replica is built for anyone who wants that clean twin-register dial on the wrist without original-market pricing. The proportions, dial layout and case finishing are matched closely to the reference, so it reads correctly at arm's length and across a dinner table. This is a replica watch, not a genuine IWC, and it is described and sold honestly as such.

Materials and Specifications
The case is machined from 316L stainless steel with brushed flanks and a mirror-polished bezel, then assembled by hand so the lugs sit square and the crown lines up cleanly. The dial is lacquered rather than printed, which gives the surface a soft depth under light, and the markers and hands are applied and polished individually. Inside runs an automatic chronograph movement with a 40-hour power reserve, driven through a column-wheel-style actuation for a crisp pusher feel. The strap is genuine calf leather with a soft lining, tapering from 20mm at the lugs to 18mm at the buckle, and takes standard replacement straps.
iw371618 Replica Fake: A Comprehensive Guide
Is this the same size as the original IW371618?
Yes. The case measures 41mm across and roughly 13mm thick, with a 20mm lug width, so it wears identically to the reference and accepts the same straps.
How close is the replica to the genuine watch?
Externally it is very close: case geometry, dial layout, crystal profile and strap hardware all follow the original. The differences sit inside the caseback, where the movement is a reliable replica calibre rather than the manufacture movement.
Does the chronograph actually work?
It does. Both pushers operate a functioning chronograph with central seconds and a 30-minute totaliser, and the reset returns cleanly to zero.
