Short answer
The replica IW371460 v1 is an early replica of the IWC Portugieser Chronograph ref. IW371460. The v1 label comes from sellers, not from IWC. No factory publishes a v1 spec sheet. Build quality changes by maker and date. Treat v1 as a batch label, not a grade.
What the original IW371460 is
Ref. IW371460 sits in the IWC Portugieser Chronograph line. The original watch uses a steel case in the 40.9 mm class, a silver dial, two subdials, a date window at 3, and a chronograph movement. IWC lists the 79350 calibre for this reference family. The movement is a modified Valjoux 7750. It runs at 28,800 vph, has 31 jewels, and carries a 44-hour power reserve. Water resistance is 30 m.

What v1 replicas tend to share
Most v1 examples copy the case shape, the two-subdial layout, the date window, and the crown and pusher stack. Many use an Asian 7750 clone. Some low-cost examples use quartz. The dial color, hand finish, and caseback engraving vary. Ask for macro photos and a movement photo before you pay.
What to check on a replica IW371460 v1
- Dial print. Look at the IWC logo, the minute track, and the text under 12. Compare thickness and spacing.
- Subdial spacing. The subdials at 12 and 6 must sit on the center line. Off-center subdials point to a module or a quartz build.
- Date window. Check the cutout shape, date font, and alignment at 3.
- Hands. Check length, shape, and finish. The chronograph seconds hand must rest at 12 after reset.
- Case finish. Check brushed and polished transitions on the lugs and bezel. Sharp edges are a defect.
- Movement. Ask for the calibre type. An Asian 7750 should show a smooth chronograph sweep and a crisp reset.
- Chronograph. Start, stop, and reset the chrono. The reset must return to zero without drag.
- Caseback. Check engraving depth, reference text, and caseback threads.
- Timekeeping. Ask for a timegrapher photo. Rate, amplitude, and beat error matter more than a seller claim.
- Water resistance. Do not assume 30 m. Replica seals are not tested to IWC standards. Keep the watch away from water.
v1 vs later batches
Later batches often correct dial print, subdial spacing, and movement decoration. A v1 can be older stock. It can also be a current low-grade build sold with a v1 label. The label alone does not prove age or quality. Compare photos of the exact watch. Ask for a timestamp and a video of the chronograph reset.
Movement notes
The original cal. 79350 is not a stock 7750. IWC reworks the layout. Replica makers use an Asian 7750 clone or a quartz movement. A 7750 clone adds height and needs service. A quartz build is thin and has a ticking seconds hand. Match the movement to the price and to the photos. If the seller cannot name the movement, walk away.
Price and risk
No public price list exists for v1 replicas. Prices move with maker, movement, and condition. IWC does not service replicas. A replica has no IWC warranty. The FTC warns that counterfeit goods carry legal and quality risks. Buy from a seller with a return policy and clear photos. Keep the claim in writing.
Bottom line
The replica IW371460 v1 is a copy of a 40.9 mm IWC Portugieser Chronograph. It can look close at arm's length. It will not match the original movement, case finish, or service support. Check the dial, date window, subdial spacing, and movement before you buy. A v1 label is not a quality mark.
