Prerequisites
- Know the reference: IWC Portofino Chronograph 42, 42mm steel case, chronograph subdials at 12 and 6, day and date at 3.
- Set a budget band: under $150, $150 to $300, or above $300.
- Pick a movement class: quartz, automatic clone, or hybrid.
Top Pick: Swiss Quartz First Copy Portofino 42
This is the pick. The case measures 42mm across and 13mm thick, which matches the original stance on a 7-inch wrist. The pushers have a firm click and the chronograph hands snap back to zero without drift. Dial printing holds up under direct light, and the applied indices sit flush. The day and date window aligns with the frame. Water resistance is rated for splashes only, so keep it away from the pool. For the price, it delivers the closest visual match and the fewest compromises.

What to check on this model
Ask for a photo of the caseback and confirm the engraving depth. Request a video of the chronograph running. Verify the strap taper at the lugs.
Option 2: Japanese Quartz First Copy
The second choice costs less and runs on a Miyota or Seiko quartz movement. The case is 42mm and the dial layout mirrors the original. The pusher feel is lighter and the reset can overshoot by a fraction of a second. Dial color runs a shade warm under tungsten light. It suits a buyer who wants the look without paying for Swiss quartz.
Option 3: Automatic Clone Portofino 42
This version uses a Chinese automatic movement with a rotor you can see through a display back. The case is often 42.5mm, so it wears larger. Thickness climbs to 14mm. The sweep second hand moves in steps rather than a smooth glide. Owners accept the trade for a mechanical feel. Service costs exceed the purchase price, so treat it as a disposable watch.
Option 4: Budget Alloy Case
The cheapest path uses an alloy case with a printed dial. Weight is light, about 60 grams on a leather strap. The plating can wear at the lugs within months. The chronograph function may be decorative on some units. Buy this only if the watch is a costume piece.
How to Compare Before You Buy
- Measure the case across the bezel and confirm 42mm.
- Check that the 12 and 6 subdials sit on a vertical line through the crown.
- Press each pusher and watch the chronograph second hand start, stop, and reset.
- Inspect the date window at 3 and confirm the day wheel sits centered.
- Request a daylight wrist shot to judge dial color and case finishing.
Verdict
The Swiss quartz first copy wins on proportion, pusher feel, and dial accuracy. The Japanese quartz version is the value pick. The automatic clone suits buyers who want a mechanical movement and accept the extra thickness. The alloy case is a last resort.
