Few chronographs have embraced the skeletonized aesthetic as consistently as the Chronoswiss Opus, a model that has defined the brand’s technical artistry for more than three decades. With the new Opus Chronograph Purple Rain, the Lucerne-based manufacture introduces a vibrant ultraviolet theme and a lightweight titanium case, celebrating the 30th anniversary of this distinctive chronograph.
Chronoswiss and the evolution of the Opus
Founded in 1983, Chronoswiss built its reputation around mechanical purism at a time when quartz watches dominated the market. Known for its onion crowns, fluted bezels, and regulator dials, the brand carved out a niche for connoisseurs who valued traditional Swiss watchmaking with a modern twist. The Opus, unveiled in 1995, was a milestone: a fully skeletonized automatic chronograph produced in series, giving enthusiasts an intimate look at the beating heart of the movement. Over the years, it has become one of the maison’s calling cards, continuously reinterpreted with new finishes and case materials.
Technical details beneath the purple glow
At 41 mm in diameter and 14.8 mm thick, the Opus Chronograph Purple Rain is crafted from grade 5 titanium, a first for this model. The case retains the brand’s signature features — the large knurled crown, extended lugs, and coin-edge bezel — while offering a more contemporary, lightweight feel on the wrist. The standout element is the dial treatment: an ultraviolet backdrop contrasts dramatically with the openworked bridges, exposing the C.741S automatic chronograph caliber within.
This movement, based on the proven Valjoux 7750 architecture, has been extensively modified and skeletonized by Chronoswiss. Operating at 28,800 vibrations per hour with a power reserve of 46 hours, it drives central chronograph seconds, 30-minute and 12-hour counters, as well as running seconds. Both the front and the sapphire exhibition back highlight the interplay of polished steel, violet accents, and mechanical depth — a constant reminder that this is a watch meant to be admired as much as worn.
A statement piece for confident collectors
The Opus Purple Rain is not designed to blend quietly into the background. With its ultraviolet color scheme, prominent skeletonization, and bold titanium architecture, it caters to collectors who want their chronograph to be both a conversation starter and a serious horological instrument. The legibility, aided by Super-LumiNova on the hands and indices, ensures the watch remains practical despite its theatrical design. Paired with a purple strap that echoes the dial’s hues, it becomes a piece that thrives in social settings, appealing to those who enjoy contemporary design but still value traditional mechanics.
Price, availability, and final thoughts
The Chronoswiss Opus Chronograph Purple Rain is limited to 50 pieces worldwide and will be available from December 2025. Priced at USD 17,700, it represents both a technical celebration and a stylistic statement within the brand’s catalog. For enthusiasts who admire skeletonization, titanium construction, and daring chromatic choices, this watch encapsulates the spirit of Chronoswiss: unapologetically mechanical, confidently different.
