The replica IW371416 v2 is a second-generation 1:1 copy of the IWC Portugieser Chronograph, built around a 40.9 mm steel case, a silver-plated bi-compax dial with a 30-minute counter at 12 o'clock and running seconds at 6 o'clock, and a decorated Asian 7750 movement finished to mirror caliber 79350. The v2 tag marks a factory revision, not a new model, so the real changes sit in case height, dial print, hand shape, and case back detail.
Replica IW371416 V10: Specs, Flaws and QC Guide
What is the IW371416 v2 replica based on?
The reference belongs to the IW3714 Portugieser Chronograph family, IWC's slim steel chronograph with leaf hands, applied Arabic numerals, and a narrow bezel. The genuine watch runs caliber 79350, a 28,800 vph movement with a 44-hour power reserve, inside a case that measures 40.9 mm across and about 12.3 mm tall.
That thin profile is the hard part to copy. Early replicas sat 1.5 mm to 2 mm too tall, which changed how the watch sat on the wrist and how the lugs looked in profile.
What changed between v1 and v2?
Version 2 targets the details that show up first in side-by-side photos.
- Case height trimmed closer to the genuine 12.3 mm, with lugs reprofiled to match.
- Subdial spacing corrected so the counters sit tight to the 12 and 6 markers instead of drifting inward.
- Dial print rebuilt with a thinner minute track and sharper numerals.
- Applied indices given the correct curve and polish, with no flat tops.
- Leaf hands slimmed and lengthened to genuine proportions.
- Sapphire crystal with a clearer anti-reflective coat and less blue reflection.
- Case back engraving cut deeper, rotor decoration closer to caliber 79350.
- Strap leather and stitching upgraded, with a closer match to the original grain.

How close is the v2 to the genuine watch?
On the wrist, the silhouette and dial layout read correctly at arm's length. Differences appear under a loupe: movement finishing, engraving sharpness, crystal clarity, and the feel of the crown when winding.
Weight is a fair proxy. A steel case over a 7750 base lands close to the genuine mass, so a watch that feels light in the hand usually points to a cheaper case set.
How do you check a v2 before you buy?
- Ask for macro photos of the dial at 12 and 6. Subdial spacing and print quality show up there first.
- Request a caliper photo of the case flank. Anything above 13 mm is a v1 leftover.
- Ask for a video of the chronograph start, stop, and reset. The 30-minute counter should snap back to zero.
- Look at the case back engraving under angled light. Shallow laser etching reads grey and flat.
- Check the crystal in daylight. A heavy blue or purple tint means older AR coating.
- Confirm buckle shape and stitching density against reference photos.
What movement is inside the replica IW371416 v2?
Most v2 builds run a modified Asian 7750 with a decorative plate engraved and finished to suggest caliber 79350. It beats at 28,800 vph and holds a power reserve near 40 hours.
The base is serviceable by any watchmaker who works on 7750 movements. Ask before purchase whether the seller stocks replacement hands and crystals, since those parts see the most wear.
Is the replica IW371416 v2 water resistant?
The genuine Portugieser Chronograph is rated to 3 bar, which covers splashes and rain only. Replica gaskets vary by batch, so treat the v2 as splash resistant at best and keep it away from swimming, showers, and steam.
Care notes for long-term ownership
- Wind the crown gently and stop at the first sign of resistance.
- Reset the chronograph to zero before storing the watch.
- Keep it away from magnetic chargers and speakers.
- Have the movement cleaned every three to five years with regular wear.
