What a Portofino Automatic replica is
A Portofino Automatic replica is a third-party copy of the IWC Portofino Automatic, ref. IW356501 and close variants such as IW356502 and IW356517. IWC prices the genuine at about $5,400. Replica sellers price the same silhouette from $85 to $650, split into three build tiers.
Genuine specs to compare against
- Case: 40.0 mm steel, 9.5 mm thick, 20 mm lug width
- Movement: Calibre 35110, base Sellita SW300-1, 28,800 vph, 42 h power reserve
- Dial: silver-plated or black, applied steel markers, date at 3
- Crystal: sapphire, antireflective coating on one side
- Water resistance: 30 m
- Strap: 20 mm alligator leather, steel pin buckle
Those six numbers answer most replica questions. A case that measures 11 mm or more is not a top-tier build. A 22 mm lug width on a Portofino is also wrong.
Portofino Automatic Watch Replica: What to Check Before You Buy
Three replica tiers
Tier 1, $85 to $130
Alloy case, quartz or low-grade automatic, printed dial, 11 mm to 12 mm thick. The date window sits off center. Caseback engraving is shallow. Skip this tier.

Tier 2, $180 to $330
316L steel, Miyota 9015 or Seagull ST2130, 40 mm case, 10.5 mm to 11 mm. Dial print is sharp but markers sit a touch high. Date font is wider than the genuine. This tier runs and keeps time.
Tier 3, $420 to $650
Claimed 1:1. Sellita SW300 clone or ETA 2892-A2 clone, 9.6 mm to 9.9 mm case, correct dial print weight, applied markers with polished edges, rotor engraving with the right stripe count. This tier passes a table check.
Six checks before you pay
- Ask for caliper photos of case thickness. Target 9.5 mm, plus or minus 0.4 mm.
- Ask for a timegrapher photo. 28,800 vph and rate within plus or minus 12 s per day.
- Compare the IWC logo. Genuine letters stand 1.4 mm tall, set 0.8 mm under the 12 marker.
- Study the date font. Genuine numerals are narrow and tall.
- Check the crown. Genuine carries the IWC probe logo, 5.5 mm wide.
- Water resistance is untested on most replicas. Do not swim with one.
Cost of ownership
A top-tier replica costs about $500. Movement service at an independent watchmaker runs $120 to $200. There is no factory warranty and no resale value. Used genuine Portofino Automatic listings sit near $3,000 to $4,200, so the price gap stays wide.
