Replica Portuguese Watches

Our iwc portuguese replica collection features 35 models covering the complete Portugieser range — chronograph, 7-day automatic, perpetual calendar, annual calendar and the new Automatic 40. The Portugieser, introduced in 1939, was IWC’s response to two Portuguese merchants requesting wristwatch-sized cases with marine chronometer precision. The result: oversized dials with railway minute tracks and slim bezels that maximize legibility. Every iwc portugieser replica in this collection runs a movement matched to genuine IWC caliber architecture with Pellaton winding, sapphire crystal and decorated finishing. Sizes span from 40mm (Automatic 40) to 44.2mm (Perpetual Calendar and Annual Calendar). Browse by reference below, or see the full Replica IWC collection.

Movement and Build

Every replica iwc portuguese in this collection uses an automatic caliber matched to genuine specification. The Chronograph IW371491 runs a column-wheel caliber 69355 with vertical clutch for smooth chronograph engagement and 46-hour power reserve. The 7-Day models carry the in-house 52000 series with double barrel and Pellaton ceramic pawl components achieving 168 hours between winds. Perpetual Calendar references use caliber 52615 with 7-day reserve plus moon phase accurate to 577.5 years. Annual Calendar caliber 52850 combines day-date-month indication with the same Pellaton architecture. Cases maintain IWC’s signature Portugieser proportions — ultra-slim bezel, oversized dial area and slender lugs. Finishing alternates between brushed case sides and polished bezel surfaces. All crystals are domed sapphire with dual anti-reflective coating. Straps are hand-stitched alligator with IWC-signed deployant buckle.

How to Choose Your Portugieser

Reference and complication define the experience. The IW371491 Chronograph at 41mm is the purest iwc portugieser chronograph replica — the two oversized counters at 12 and 6 are the most recognizable Portugieser element. The IW500705 7-Day at 42.3mm appeals to movement enthusiasts with its visible power reserve and week-long autonomy. The IW503312 Perpetual Calendar at 44.2mm delivers IWC’s most complex dial layout with moon phase and century indication. The IW504402 Annual Calendar offers most of the perpetual calendar’s convenience with a simpler once-per-year correction. The IW358305 Automatic 40 fits modern wrists while preserving the Portugieser DNA. For IWC’s aviation heritage instead, explore the Pilots collection.

Frequently Asked Questions

What is the difference between the Portugieser Chronograph and 7-Day?

The Chronograph (IW371491, 41mm) features start-stop-reset timing with two subdials — running seconds at 6 and 30-minute counter at 12. The 7-Day (IW500705, 42.3mm) is a time-only watch with small seconds at 9 and power reserve display at 3, offering a full 168-hour reserve from a single barrel winding. The Chronograph uses caliber 69355 with column wheel. The 7-Day uses caliber 52010 with double barrel Pellaton system. Choose chronograph for timing functionality, 7-Day for maximum autonomy.

What is the Pellaton winding system?

Pellaton is IWC’s proprietary automatic winding mechanism, invented by technical director Albert Pellaton in 1950. Instead of a traditional reverser wheel, it uses two pawl levers that alternate engagement with a ratchet wheel, winding the mainspring efficiently in both rotor directions. Modern Portugieser calibers (52000 series) use ceramic pawl components that virtually eliminate wear. This system enables the 7-day power reserve found in the IW500705 and powers the Perpetual and Annual Calendar movements.

What is the difference between perpetual and annual calendar?

The Perpetual Calendar (IW503312) automatically tracks months with 28, 30 and 31 days plus leap years — no manual correction needed until February 2100. It includes moon phase and 4-digit year display. The Annual Calendar (IW504402) tracks 30 and 31-day months automatically but does not account for February — requiring one manual correction per year on March 1st. The annual calendar is a simpler, thinner mechanism with fewer components. Both are 44.2mm in this collection.

What sizes are available in the Portugieser collection?

The Portugieser range offers four size categories: 40mm (Automatic 40, IW358305), 41mm (Chronograph, IW371491), 42.3mm (7-Day Automatic, IW500705) and 44.2mm (Perpetual Calendar IW503312 and Annual Calendar IW504402). Case thickness ranges from 12.3mm on the Automatic 40 to 14.9mm on the Perpetual Calendar. The 40mm and 41mm references suit most wrists, while the 44.2mm calendar models are designed for larger wrists given their complication height.

What makes the Portugieser dial design distinctive?

Three elements define the Portugieser aesthetic: an ultra-slim bezel that maximizes dial area relative to case size, a railway minute track (chemin de fer) around the outer dial edge with printed minute markers, and leaf-shaped (feuille) or dauphine hands. The chronograph models add oversized subdials at 12 and 6 o’clock that dominate the dial layout. This design language originated in the 1939 reference 325 and has remained consistent across eight decades. The large dial area, originally requested for marine chronometer legibility, now defines the Portugieser identity.
