The closest practical equivalent to a fake IWC Portofino Small Seconds in a 33 mm case is a 33 to 34 mm dress watch with a running-seconds sub-dial at 6 o'clock, an 8 to 9 mm case height, plain Roman or baton markers, and a slim leather strap. That specification, not one reference number, is what shoppers mean by this phrase. The criteria behind the picks below: case diameter and lug-to-lug on a small wrist, where the seconds sit on the dial, which movement can deliver a 6 o'clock sub-dial, dial legibility at 33 mm, and how easy the watch is to service later.
The reference problem: IWC never made this watch
IWC's Portofino Automatic 33 is a 33 mm watch, and it runs center seconds. IWC's small-seconds Portofino models sit in the Hand-Wound Eight Days family, which is much larger than 33 mm. No factory reference combines both traits, so "Portofino Small Seconds 33" describes a look rather than a catalog entry. A first copy that nails the look beats one that chases a reference number nobody made.
Pick 1: 33 to 34 mm sub-seconds dress watch on a Miyota 8N33-class movement
This is the top pick for most buyers. The 8N33 movement family was built for small cases with a sub-dial around 6 o'clock, so a 33 mm case is not a compromise, it is the intended size.
Fake Portofino Small Seconds 33 Synonym
- Pros: correct 33 to 34 mm diameter for a 14 to 16 cm wrist; sub-seconds at 6 matches the Portofino dial layout; thin enough to sit under a cuff; parts and service are common.
- Cons: lower beat rate than Swiss movements, so the sweep looks choppier; hand-winding feel is plain; some aftermarket cases feel hollow in the hand.
Choose this if you want the look on a small wrist and plan to wear the watch instead of storing it.

Pick 2: 34 mm build on a Sellita SW260-1
The SW260-1 places small seconds at 6 o'clock and is the Swiss option most builders reach for when the dial needs a sub-dial instead of a center hand.
- Pros: smoother sweep; better hand-winding feedback; 34 mm still reads as a dress watch, not a bracelet watch; easier to find a watchmaker who will open it.
- Cons: costs more, which pushes the price of a first copy upward; the extra millimeter can look large on a very thin wrist; not needed if you only care about the dial from arm's length.
Choose this if the watch is a daily wearer and you want a movement that a local shop can regulate.
Pick 3: 32 to 34 mm vintage-style small seconds
Domed crystal, printed minute track, leaf or dauphine hands, and a sub-dial placed low on the dial. This reads older than the Portofino line but suits the same wrist.
- Pros: closest match to a classic small dress watch; 32 mm cases exist for wrists under 14 cm; light and quiet on the wrist.
- Cons: 32 mm can look undersized on a 17 cm wrist; vintage-style dials often use acrylic crystals that scratch; strap options are narrower, often 16 mm.
Choose this if you already own a 36 to 38 mm watch and want something lighter for formal wear.
What to check on any first copy before you pay
- Sub-dial position: it must sit at 6 o'clock and stay clear of the center hands through a full turn.
- Case height: anything past 10 mm loses the Portofino profile under a shirt cuff.
- Dial printing: look at the markers under a phone light. Soft edges show on a 33 mm dial fast.
- Crown size: a tiny crown on a thick case is hard to wind and a common flaw on small copies.
- Strap and lugs: 17 to 18 mm lugs give you real strap choice. Odd widths limit you.
Which one fits your use case
Wrist under 16 cm, budget-first: Pick 1. Daily wearer with a watchmaker nearby: Pick 2. Formal wear only, and you like domed crystals: Pick 3. In every case, confirm the movement inside before ordering, because the dial alone cannot tell you whether the seconds sub-dial is driven correctly.
