The IW371618 is the stainless steel, silver-dial version of the IWC Portugieser Chronograph, and it is one of the most requested references on the replica market. A well-built fake IW371618 reproduces the 41 mm case, the two-register chronograph dial, and the slim leaf-shaped hands closely enough that the silhouette reads correctly from across a room. This guide covers what to look at before you order one.

Key Features

  • 41 mm stainless steel case with the thin, elegant Portugieser bezel
  • Two-register chronograph layout with subdials at 12 and 6 o'clock
  • Silver-plated dial with applied Arabic numerals and a printed minute track
  • Leaf-shaped hour and minute hands with a slender chronograph seconds hand
  • Sapphire crystal with anti-reflective coating for clear reading at an angle
  • Automatic chronograph movement with roughly a 44-hour power reserve
  • Alligator-grain leather strap with a steel pin buckle and quick-release pins
  • Water resistance rated to 3 ATM for everyday splash protection

Materials and Specifications

The case is machined from 316L stainless steel and finished with a mix of polished and lightly brushed surfaces, matching the original's dressy feel. Case dimensions come in at approximately 41 mm across and about 13 mm thick, with a 20 mm lug width, so most aftermarket straps for the genuine reference will fit. The dial uses applied metal numerals rather than printed ones, which is one of the easiest details to check when comparing photos. Inside, the chronograph runs on an automatic movement in the Valjoux 7750 family, a robust, widely serviced architecture with a column-free cam switching system.

Shipping and Returns

Orders are packed discreetly and dispatched within one to two business days, with tracking provided once the parcel leaves the warehouse. Delivery is typically a few days domestically and one to three weeks for international addresses, depending on customs processing. If the watch arrives with a defect or does not match the listing, returns or exchanges are accepted within 30 days of delivery, provided the piece is unworn and still carries its protective film.

Does the replica IW371618 have a working chronograph?

Yes. The pushers at 2 and 4 o'clock start, stop, and reset the chronograph, and the two subdials sweep and count minutes the way the original does. Expect a slightly lighter pusher feel than a genuine IWC in-house calibre.

How close is a fake IW371618 to the genuine watch?

Externally it is very close: case proportions, dial layout, and hand shape all follow the original reference. The main differences sit in the movement finishing and the weight of the crown action, which are hard to replicate at this price point.

What should I check before ordering?

Confirm the dial colour and strap option in the listing photos, verify the stated case diameter, and read the returns window. Ask for real photos of the exact piece rather than stock images whenever the seller offers them.
