TW Factory IWC Portofino Chronograph IW391036 “Portofino Chrono” Rose Gold Super Clone Replica

Correct Model Identification (Confirmed)

The watch shown corresponds to the IWC Portofino Chronograph, reference IW391036.

This reference is the rose gold variant of the Portofino Chronograph line and can be identified by the following elements:

• 42mm Portofino chronograph case

• Rose gold case tone with polished finish

• White dial with classic Portofino typography

• Tri-compax chronograph layout

  • 30-minute counter at 12

  • Small seconds at 9

  • 12-hour counter at 6

• Day + date window at 3 o’clock

• Roman numerals at 12 and 6 only

• Leaf-shaped chronograph hands

• Pump-style chronograph pushers

• Solid caseback

Among Portofino chronographs, this reference is considered the most formal expression of the model.

Why This TW Version Qualifies as a Super Clone

Chronographs are unforgiving. Poor pusher feel, unstable reset alignment, or uneven sub-dial spacing will surface quickly in real use. TW Factory avoids the usual replica pitfalls by building this watch around a properly modified chronograph movement, rather than forcing a generic solution into a dress case.

All chronograph functions are fully functional:

• Central chronograph seconds

• 30-minute chronograph counter

• 12-hour chronograph counter

• Running seconds

• Functional day and date display

Nothing is decorative. Everything exists to be used, which is the baseline requirement for a chronograph to remain credible over time.

Case Proportions and Rose Gold Execution

At 42mm, the case size matches the genuine Portofino Chronograph and wears slimmer than expected thanks to controlled mid-case thickness. While any 7750-based chronograph carries inherent height, TW manages the profile well enough to remain cuff-compatible in real wear.

The rose gold PVD finish is warm and even, avoiding the orange or copper hue that immediately exposes lower-quality replicas. Under indoor lighting, the tone stays soft and refined rather than reflective or flashy.

Polishing is consistent across the bezel, case flanks, and lugs, with clean transitions that preserve the Portofino’s elegant silhouette.

Dial Layout and Chronograph Balance

The white dial is disciplined and calm, which is essential for a dress chronograph.

Key strengths of the execution:

• Sub-dials are correctly spaced and centered

• Leaf-shaped rose gold hands remain legible without aggression

• Day/date window sits cleanly at 3 without crowding

• Roman numerals anchor the dial without overpowering it

The printed minute track is precise and evenly spaced, supporting accurate chronograph reading while remaining visually secondary to the time display.

Crystal and Optical Behavior

The watch uses a sapphire crystal with anti-reflective coating, keeping glare under control without introducing a blue or purple tint. This is especially important on a white dial, where poor AR treatment becomes obvious indoors.

The crystal profile remains restrained, preserving the classical Portofino appearance.

Movement: Dandong 7750 Modified to Cal. 4601 Architecture

TW Factory equips this model with a Dandong 7750 automatic chronograph movement, modified to follow the IWC Cal. 4601 functional layout used in the genuine Portofino Chronograph.

Practical ownership characteristics include:

• 28,800 bph automatic operation

• Stable chronograph engagement

• Clean start, stop, and reset behavior

• Reliable day/date switching

• Predictable hand-setting resistance

This is not decorative mimicry. The modification focuses on function, stability, and usability, which is exactly what matters in a daily-wear chronograph. As with any mechanical chronograph, sensible use is assumed—reset only when stopped, and avoid unnecessary abuse.

Strap Material and Wearing Comfort

The watch is paired with a brown calfskin leather strap, supple but structured, with light padding that supports the case without adding bulk. The strap complements the rose gold case naturally, maintaining the formal character of the watch.

Break-in is smooth, and the strap holds shape over time, keeping the watch centered during extended wear.

Who This Watch Is For

This model is for wearers who want a true dress chronograph, not a sport watch in disguise. It fits professional environments, formal settings, and daily rotation where versatility and restraint matter.

It is not designed for those seeking ultra-thin chronographs or exhibition casebacks. This watch prioritizes balance, function, and long-term usability.

TW Replica vs Genuine Comparison

This TW Factory Portofino Chronograph IW391036 succeeds by managing complexity rather than hiding it, delivering a rose-gold dress chronograph that remains coherent and usable long after first impressions fade, with the final judgment—rightly—left to the wearer.
