Key Highlights
- Skeletonised Calibre SXH7, a re-engineered interpretation of SXH5
- Escapement and stop-seconds mechanism reversed to be visible on the dial side
- Small seconds at 4:30 on a smoked sapphire sub-dial
- Deep “Cosmic Blue” peripheral dial for legibility and contrast
- 40.5 mm Antarctique and 38.5 mm Antarctique S titanium cases, limited to 50 and 25 pieces per year
A Movement Turned Inside Out
The Antarctique Révélation debuted in 2023 after a collector asked Czapek to invert its in-house calibre, revealing what usually hides behind the dial. Rather than simply open-working Calibre SXH5, the manufacture re-engineered it entirely to create Calibre SXH7, conceived from the start to be admired from the dial side.
The escapement is now reversed and fully visible on the front of the watch, its precise geometry constantly in motion. The stop-seconds mechanism has also been brought to the dial side, so its action is revealed each time the crown is pulled for setting. The result is a piece that shows how the watch works as clearly as it shows the time.
Architecture in Trompe-l’Œil
Inverting the movement demanded extensive skeletonisation. The main plate is opened to create a trompe-l’œil effect that suggests a constellation of bridges, while still echoing the structural language of SXH5. Because the seconds hand can no longer share a central axis with the hours and minutes, it has been moved to a small seconds display at 4:30.
Smoked Sapphire and Subtle Anchors
The small seconds indications are printed on a smoked sapphire crystal sub-dial, attached discreetly to the hours and minutes track to preserve transparency. With the oscillating mass now visible from both dial and caseback, it has been engraved and decorated so that every angle maintains the same level of finishing.
Cosmic Blue: A Visual Anchor
Skeletonised watches must balance openness with clarity. On the Antarctique Révélation Titanium Cosmic Blue, the deep peripheral dial acts as a strong chromatic frame for the hour and minute track, defining the display against the openworked bridges beneath.
The contrast between the rich blue ring, the cool hue of titanium and the bright movement components guides the eye quickly to the time. At the same moment, it encourages a slower reading of the mechanical landscape, echoing Czapek’s preference for technical content expressed through calm, deliberate design.
Two Sizes, Two Limited Productions
The Révélation Titanium Cosmic Blue is available in two Antarctique case dimensions. The 40.5 mm Antarctique case is produced in an annual run of up to 50 pieces, while the 38.5 mm Antarctique S case is limited to up to 25 pieces per year. Both share the integrated bracelet construction and the lightweight comfort of titanium that define the Antarctique as a modern sports-luxury design from an independent manufacture.
Why It Matters
For collectors across the GCC who follow independent haute horlogerie, the Antarctique Révélation Titanium Cosmic Blue is a focused evolution of an already notable reference. It brings the engineering of Calibre SXH7 to the foreground, pairing visible mechanics with a carefully judged use of colour and measured production numbers.
It is a watch that rewards close looking and repeat wear, aligning with a collecting culture that values depth of execution as much as rarity and design.
Frequently Asked Questions
What is the Calibre SXH7 and how does it differ from the original SXH5?
The Calibre SXH7 is a re-engineered interpretation of the SXH5, conceived from the start to be admired from the dial side rather than simply open-worked. The escapement and stop-seconds mechanism have been reversed and repositioned to be fully visible on the front of the watch, revealing how the watch works as clearly as it shows the time.
Why is the small seconds display located at 4:30 on the Antarctique Révélation?
Because the seconds hand can no longer share a central axis with the hours and minutes hands due to the inverted movement architecture, it has been repositioned to a small seconds display at 4:30 on a smoked sapphire sub-dial to preserve the transparency of the skeletonised design.
What are the production limits for the two Antarctique case sizes?
The 40.5 mm Antarctique case is produced in an annual run of up to 50 pieces, while the 38.5 mm Antarctique S case is limited to up to 25 pieces per year.
