ZF Edition — Leather Strap

ZF’s iteration of the IW371605 Portugieser Chronograph represents a significant technical milestone, resolving the historical thickness issues of earlier A7750-based replicas. By developing a bespoke movement architecture, ZF achieves the correct case proportions and sub-dial spacing required for this reference, making it the established benchmark on horological forums.

The proprietary ZF 69355 clone caliber features a functional column wheel and vertical clutch mechanism, ensuring crisp chronograph actuation. This architecture mirrors the genuine layout, allowing for an accurate open caseback display without the bloated profile of standard chronograph clones. Approximately 36 hours of power reserve.

Machined from 316L stainless steel, the 41mm case features alternating brushed flanks and polished lugs. The silver-plated dial is appointed with thermally quenched blue steel hands, providing a deep metallic luster rather than the flat appearance of painted alternatives.

This caliber features a functional column wheel, delivering tactile and precise feedback during chronograph engagement. The open caseback reveals perlage and circular graining that closely approximates the genuine finish, while the rotor operates with improved stability over earlier modular chronographs.

⏱ Accuracy Profile:

±10–15 s/day. Standard regulation for this complex chronograph clone prioritizes reliable engagement and amplitude stability.

Why ZF for This Reference?

Many collectors ask: “Why not AZF?”

The ZF iteration remains the community benchmark primarily due to its proprietary 69355 clone movement, which allows the case to sit at the exact 13.3mm thickness of the genuine IW371605. Previous iterations and lesser factories rely on modified A7750 movements, resulting in a noticeably bloated case profile exceeding 14.5mm.

Full Disclosure: The factory-supplied leather strap is notoriously stiff out of the box; most serious collectors immediately upgrade to a premium aftermarket leather or alligator strap for optimal comfort.

Collector Q&A

Q: Why is the thickness of this ZF model significant compared to older versions?

A: Older replicas of the Portugieser Chronograph used modified Asian 7750 movements, which forced the case thickness to exceed 14.5mm. ZF developed a custom 69355 clone movement, allowing this model to achieve the genuine-accurate 13.3mm thickness.

Q: Are the blue hands on the dial painted or thermally treated?

A: The hands and applied numerals on this ZF IW371605 are thermally quenched (fired) blue steel. This traditional horological process provides a deep, metallic luster that shifts under different lighting conditions, unlike the flat appearance of painted hands.

Q: Does the chronograph function work exactly like the genuine?

A: Yes, the ZF 69355 clone features a fully functional column-wheel chronograph. The top pusher starts and stops the central seconds hand, while the bottom pusher resets it. The vertical sub-dial layout accurately tracks elapsed minutes.

Q: What is the most common critique of this specific factory release?

A: While the case and movement are highly praised, the factory-supplied leather strap is noticeably stiff and lacks the supple feel of genuine IWC alligator leather. Most collectors factor in the cost of a high-quality aftermarket strap to complete the build.
