“Czapek Promenade Transparencies Aqua Blue: Now You See It, Now You See Even More of It.”
There’s something rather amusing about the lengths watchmakers will go to in order to make a dial more interesting. Some add guilloché, others throw in a bit of enamel, and a few decide that the best solution is to get rid of the dial altogether.
Czapek, thankfully, has opted for something a little more sophisticated with the new Promenade Transparencies Aqua Blue. Following the original Viridian Green edition, this latest interpretation brings a smoky blue sapphire crystal dial to the Promenade collection, offering a tantalising view of the mechanical workings beneath without completely giving away the show.
Think of it as watchmaking’s equivalent of frosted glass. You can see what’s going on behind it, but there’s still enough mystery to keep things interesting.
“A Dial That Isn’t Quite a Dial”
The Aqua Blue’s defining feature is its sapphire crystal dial, which uses a metallisation process to create a graduated blue fumé effect. Rather than painting or tinting the crystal itself, Czapek applies a metallic coating to the underside of the sapphire disc through vapour deposition.
This coating consists of microscopic dots, approximately eight microns in diameter, distributed at varying densities across the surface. The dots become progressively denser towards the outer edge and thinner towards the off-centred small seconds display at 4:30, producing a gradient that transitions from transparent in the centre to increasingly opaque around the periphery.
The result is a dial that reveals the movement beneath while retaining enough visual structure to keep the watch from looking like someone forgot to install a dial during assembly.
Compared with the original Viridian Green edition’s metallic hour markers, the Aqua Blue introduces hand-applied blocks of light blue Super-LumiNova. These markers glow in the same light blue tone in darkness, adding another layer of visual continuity to the design.
And then there’s the small seconds display at 4:30, which remains one of the Promenade collection’s signature design elements. It also happens to be the starting point for the dial’s blue gradient, giving the whole arrangement a subtle sense of direction rather than making the transparency feel like a gimmick.
“All Eyes on the Movement”
Of course, a transparent dial is only as interesting as whatever happens to be hiding underneath it. Fortunately, Czapek has something worth showing off.
The Promenade Transparencies Aqua Blue is powered by the in-house Calibre SXH7, a fully skeletonised evolution of the brand’s Calibre SXH5. The movement has been redesigned specifically to look compelling from both the dial side and the caseback, which is a rather important consideration when there’s precious little dial material to hide behind.
Its seven openworked bridges stretch from the outer edge of the movement towards the gear train, drawing inspiration from the multi-bridge architecture found in François Czapek’s 19th-century pocket watches.
Getting the movement to work visually from the front required some serious rearranging. The escapement was reversed, the small seconds display was relocated to 4:30 and configured to be driven directly by the fourth wheel, and the crown and keyless works were redesigned to accommodate the dial-side view.
In other words, this isn’t simply a conventional movement with a few bits removed and a transparent disc slapped on top. There’s considerably more engineering involved than that.
The automatic winding system uses a micro-rotor machined from 100% recycled platinum, engraved on both faces. The movement’s finishing is also carried out symmetrically, with openworked ratchets, sandblasted rhodium-plated bridges, straight-grained flanks, and hand-chamfered inward angles visible from both sides.
That’s a considerable amount of decorative work for something that will spend most of its time attached to your wrist, where the majority of people will probably be too busy checking the time to appreciate the hand-chamfering. But then, that’s rather the point of a watch like this: the pleasure is in knowing the details are there, even if you occasionally need a loupe and some good lighting to appreciate them.
“Keeping Things Compact”
Despite all that visual complexity, Czapek has kept the Promenade Transparencies Aqua Blue relatively restrained in its proportions.
The stainless steel case measures 38 mm in diameter, 10.8 mm thick, and 42 mm from lug to lug. Curved lugs and hollowed case flanks contribute to its slender profile, while sapphire crystals on both the front and back feature internal anti-reflective treatment to minimise glare and keep the movement visible.
Water resistance is rated at 50 metres, which should be perfectly adequate for everyday wear. That said, given the amount of engineering and finishing involved, we’d probably leave the more enthusiastic underwater adventures to something a little less transparent.
The watch is paired with a dark blue nubuck leather strap, with a stainless steel Milanese mesh bracelet available as an alternative. Both offer different interpretations of the same design, whether you prefer the softness of leather or the more contemporary, integrated appearance of mesh.
Limited to 38 Pieces
The Czapek Promenade Transparencies Aqua Blue is limited to just 38 pieces, making it a relatively exclusive proposition even by the standards of independent Swiss watchmaking.
Pricing is set at CHF 28,800 (RM141,108) a.k.a. “there’s no way any of us can truly afford it”. The watch became available to order on 20 August 2026 through Czapek’s authorised retailers worldwide, its Geneva flagship boutique, and the brand’s official website.
Ultimately, the Promenade Transparencies Aqua Blue is a watch that makes a fairly compelling argument for the idea that a dial doesn’t necessarily need to conceal anything to be interesting. By using a carefully metallised sapphire disc and a movement engineered for viewing from both sides, Czapek manages to strike a balance between transparency and restraint.
It’s mechanical theatre, really. And unlike an actual theatre production, you don’t have to worry about someone in the front row blocking the view.
