The Ulysse Nardin Classico reference 8156-111/90 measures 40 mm across with a case thickness of 10 mm, defined by a streamlined ultra-thin silhouette. Ulysse Nardin appeals mainly to affluent, seasoned watch connoisseurs who appreciate top-tier luxury watch craftsmanship and premium watchmaking brands.

This replica from FK Factory precisely matches the genuine watch in case dimension and thickness. A unique individual serial number is engraved on the left side of the case, consistent with genuine specimens. It is fitted with identical double-layer blue anti-reflective coating plus protective film. The dial layout, hands, and printed date fonts replicate the original scale and visual effect completely. Identical finishing techniques are applied to the bezel, case housing, perlage inner cover, case back, knurled crown, spring bars and case-back screws, enabling true physical interchangeability with original parts.

We previously mentioned the Seagull 2892 and SW300 movements, so we will briefly explain the background of these two calibers. Sellita originally operated as a processor specialising in reworking ETA movements and relied heavily on ETA supplies. When ETA imposed movement supply restrictions, Sellita suffered severe business impact. Drawing on years of experience modifying ETA movements, Sellita developed its own movement lineup by replicating mainstream ETA automatic calibers, bringing viable alternatives to numerous watch brands dependent on ETA movements, including Tudor, Longines, Enicar, Ernest Borel, Cartier, Breitling and more.

Sellita’s core movements consist of three main models: the SW200 (clone of ETA2824), the SW300 (clone of ETA2892), and the SW500 (clone of ETA775). Additional complication movements are derived from these three foundational calibers. For instance, the entry-level IWC Portofino three-hand watch is built upon a refined SW movement base.

SW movements share nearly identical structural layout, physical dimensions, beat frequency and power reserve with their ETA counterparts, while differing slightly in individual component design and jewel count. Much like ETA calibers, SW movements are produced in multiple grades with varied decoration levels. It is therefore inaccurate to claim all SW movements lack precision or refined finishing; chronometer-certified SW variants are readily available. Inferior performance only stems from cost-cutting low-grade batches selected by some watch manufacturers. Notably, the genuine Ulysse Nardin watch in question is factory-equipped with a base SW300 movement.

With this background explained, it is easy to understand why manufacturers adopt the Seagull 2892 as a drop-in substitute for the original SW300 movement: the two calibers match fully in structure, thickness and mounting footprint. Below are real-life shots of this Ulysse Nardin replica watch.
