Czapek Promenade Transparencies Aqua Blue

Two years after the viridian green original, Czapek brings its metallised sapphire dial back in a cooler palette, over the skeletonised SXH7 and limited to 38 pieces.

• Czapek has revived its metallised sapphire dial technique in a cooler palette, two years after the Fratello collaboration that introduced it in viridian green.
• The gradient comes from metallic dots roughly eight microns wide, packed densely at the rim and thinned towards the centre so the movement shows through.
• Limited to 38 pieces on nubuck or a Milanese mesh, priced at CHF 28,800 excluding tax, with no Australian figure published.

If you looked at the Czapek x Fratello Promenade Transparencies two years ago and decided the interesting part was not the green but the technique, you were reading it correctly. No house spends that long learning to grow a gradient out of metal dots only to use it once. The colour was always the removable part. What Czapek had actually built was a way of taking a sapphire disc from clear to solid without paint, and this week that method returns in a cooler register as the Promenade Transparencies Aqua Blue.

Thirty eight millimetres, thirty eight watches, and no accident in that

The Promenade case is unchanged and that is the right call, because at 38mm across and 10.8mm thick it is already about as much watch as a skeletonised dial can carry without becoming a display cabinet. Czapek hollows the flanks and curves the lugs, which is what keeps a case of that depth from reading as a puck on the wrist. Sapphire sits front and back with anti-reflective treatment on the internal faces only, so the view stays clean while the outer surfaces keep their hardness.

Water resistance is 50 metres, which on this watch means what it always means on a dress piece: rain, a sink, a spilled drink, and nothing you would plan for. The limitation is 38 pieces, matching the diameter in millimetres, and Czapek is unlikely to have arrived at that number by chance.

Eight microns of metal, and why the centre stays clear

The blue is not lacquer and it is not pigment. Czapek metallises the underside of the sapphire disc with microscopic dots roughly eight microns across, then varies how densely they are packed: thin near the middle, crowding towards the rim. The eye reads that as a fumé gradient, but it is really a question of how much bare sapphire is left between the dots, which is why the transition looks continuous rather than sprayed. Hold it at an angle and the movement underneath swims in and out of view.

The indexes are light blue Super-LumiNova, applied by hand directly onto the crystal rather than onto a chapter ring. In daylight they read as a slightly chalky, swimming-pool blue against the darker rim, closer to the inside of a mussel shell than to anything on a dive bezel. After dark they glow the same colour they were, which is a smaller trick than it sounds and a rarer one.

Seven bridges, a reversed escapement, and a small seconds with nowhere to hang

The Calibre SXH7 is Czapek's own, an evolution of the SXH5 that had to be substantially rethought once the main plate was skeletonised. Reversing the escapement was the first consequence. The second was more awkward. With the plate opened up the seconds hand could no longer be carried on a bridge to the centre, so the sub-dial moved to 4:30 and now rides on a sapphire ring quietly fixed to the larger ring holding the hours and minutes. It is a solution you only notice when you go looking for what is holding it up.

Seven openworked bridges span the gear train, a shape Czapek traces back to the multiple-bridge architecture of François Czapek's own nineteenth century pocket watches. The calibre runs at 4Hz and stores 60 hours, so a watch taken off on Friday evening is still running on Sunday night and will want winding before Monday. Winding is by micro-rotor, machined from 100 per cent recycled platinum and engraved on both faces, because in a movement with nothing hidden there is no back of anything.

The part I keep going back and forth on

I have never fully made peace with skeleton dials, and the usual reason is that you buy a watch to read the time and then spend a year squinting at eleven o'clock. This one mostly answers that, because the gradient does the work a printed dial normally does: the markers sit against the densest, darkest part of the disc, where there is something behind them to push against. Where I still hesitate is the middle, where the hands cross the clearest section and the openworked plate is at its busiest. On the brand's own close-ups the blued plate is dark enough that I think it holds. In a dim restaurant I suspect it will not, and I have talked myself into being fine with that.

Nubuck or Milanese, and what each does to those 10.8 millimetres

The standard fit is a dark blue nubuck strap, hand stitched tone on tone and tapered from the lug so it does not add visual thickness to a case that is already carrying some. Nubuck is the right texture here, napped rather than glossy, echoing the dial's metallised surface instead of arguing with it. The alternative is a stainless steel Milanese mesh, which drops the temperature of the whole thing considerably and turns a warm dress watch into something more technical. Neither is the obvious winner, which is unusual and rather good.

Czapek Promenade Transparencies Aqua Blue pricing and availability

The Promenade Transparencies Aqua Blue is limited to 38 pieces and is offered on either the dark blue nubuck strap with a steel pin buckle or a stainless steel Milanese mesh bracelet. Czapek lists it at CHF 28,800, which is the maison's international price and excludes tax. No Australian price has been published, and the watch is not yet listed on Czapek's United States storefront. Every piece carries a three year international warranty.

Nothing here is hidden, and everything follows from that. By Czapek's own account the original Transparencies dial took more than two years of research and development, all of it spent building a surface whose job is to get out of the way of the movement. The bridges are then finished on both faces, on the assumption that somebody will look. That is a far more exposed position than a solid dial and a nice caseback, and it only works if the mechanics underneath survive the attention. These do. Full marks for transparency, which for once is not a figure of speech.
