Zenith Chronomaster Sport Skeleton: A Transparent Take on a Modern Classic

Introducing the Zenith Chronomaster Sport Skeleton

Zenith has long been a cornerstone of high-performance chronograph manufacturing, and the Chronomaster Sport collection stands as one of its most celebrated families. In 2026, the brand unveiled the Chronomaster Sport Skeleton, a model that merges the collection’s robust design with the intricate artistry of skeletonization. This release reinforces Zenith’s position as a formidable contender in the luxury chronograph segment, offering an alternative to iconic models like the Rolex Daytona.

Case and Design

The Chronomaster Sport Skeleton retains the familiar dimensions of the series: a 41mm case with a 13.6mm thickness and a 47mm lug-to-lug distance. This proportions ensure a balanced presence on the wrist, suitable for a range of wearers. The case is available in stainless steel or precious metals, with the latter offered with or without diamond-set bezels. The steel versions provide a more accessible entry point, though all models carry a premium price tag consistent with Swiss luxury watchmaking.

Movement: El Primero 3600 SK

At the heart of the skeleton is the El Primero caliber 3600 SK, a movement that continues Zenith’s legacy of high-frequency chronographs. Beating at 5Hz (36,000 vibrations per hour), it enables precise 1/10th-second chronograph readings. The skeletonized architecture reveals the intricate mechanics, including a silicon escape wheel and lever, a stop-seconds mechanism, and a skeletonized oscillating weight. The movement comprises 311 components and offers a power reserve of 60 hours, ensuring reliable performance for daily use.

Dial and Features

The dial is a showcase of transparency, featuring a tinted sapphire crystal that offers a front-facing view of the movement. Three subdials are distinguished by different colored rings: a 60-minute counter and a 60-hour counter, both with red-tipped hands, and a running seconds subdial at 9 o’clock. The central chronograph hand is also tipped in red for easy readability. The baton-shaped hour and minute hands, along with hour indices, are rhodium-plated, faceted, and coated with SuperLuminova SLN C1 for enhanced visibility in low light. A fixed, monoblock ceramic bezel—available in black or green—features a 1/10th-second scale, allowing precise time reading.

Bracelet and Strap Options

Zenith pairs the Chronomaster Sport Skeleton with a tapered stainless steel bracelet that mimics the style of an Oyster bracelet, complete with a folding clasp that offers micro-adjustment in 2.5mm steps across five settings, providing up to 10mm of total adjustability. Additionally, each model includes a premium rubber strap that matches the bezel color, offering versatility for different occasions.

Pricing and References

The stainless steel versions are retailed at ,700, with two references: one with a black ceramic bezel (Ref 03.3130.3600/01.M3130) and one with a green ceramic bezel (Ref 03.3131.3600/01.M3130). Precious metal versions are available at a significantly higher price point, reflecting the use of gold and optional diamond settings.

Final Thoughts

The Zenith Chronomaster Sport Skeleton is a compelling choice for enthusiasts seeking a modern, collector-grade chronograph with a transparent aesthetic. Its combination of high-frequency accuracy, skeletonized craftsmanship, and versatile styling makes it a worthy consideration for those who appreciate fine watchmaking. While the price is substantial, the value lies in the movement’s heritage and the brand’s reputation for producing reliable, high-performance timepieces.
