A Portugieser Perpetual Calendar replica costs $380 to $900 in most cases. Budget builds with decorative subdials sit near $150 to $250. Top-tier versions with a working moon phase and a modified Valjoux 7750 base reach $900 to $1,500. Anything under $120 is a quartz piece with printed dial elements, not a functioning calendar.
Why the price spread is wide
The genuine IWC Portugieser Perpetual Calendar retails in the $30,000 to $40,000 range, so a replica at $500 represents roughly 1.5 percent of the real cost. The gap between a $200 replica and a $1,200 replica is not branding. It is the movement, the calendar module, and the finishing hours spent on the case and dial.

$700 to $1,500
Modified Valjoux 7750 or a clone with a rebuilt calendar train. Correctly sized case (about 44.2 mm), applied indices, proper moon phase disc, and a movement that advances the calendar correctly. Hand-finishing on bridges and rotor.
What drives the cost
- Movement base: a 7750 platform costs several times more than a generic Asian automatic.
- Calendar module: a true perpetual mechanism versus a simple annual or decorative layout.
- Case finishing: brushed flanks, polished bevels, and correct lug geometry take machine time.
- Dial work: applied numerals, sunburst finish, and a correct moon phase aperture.
- Strap: alligator-grain leather versus genuine leather with a signed buckle.
Before you pay
- Ask the seller for the exact movement name and a photo of the caseback.
- Request a short video showing the date and moon phase advancing.
- Confirm case diameter and thickness against the genuine reference.
- Check the return window in writing before sending payment.
- Verify the seller accepts a payment method with buyer protection.
Legal reality
Replica watches infringe trademarks. U.S. Customs can seize shipments of counterfeit goods at the border, and the seller, not the buyer, carries the main legal exposure. Budget accordingly and treat any purchase as a final-cost decision, since returns across borders are difficult.
