Czapek & Cie Antarctique Rattrapante Ice Blue Limited Edition

Swiss luxury watch brand Czapek & Cie has released a new edition of its Antarctique Rattrapante. The sportive, open-worked split-second chronograph now appears with a touch of blue that enhances the hands and rings on its dial.

The Antarctique Rattrapante Ice Blue watch features a brilliant open-worked architecture offering magnificent view of a very complex grande complication. By doing away with the traditional dial and removing material from the plates and bridges, the mechanism is revealed. This technique requires great care with the decorating, the beveling, the polishing, and the various types of finish.

Furthermore, as material is removed from structural parts, invisible tensions in the metal can lead to deformation of the now filigree bridges. These have to provide stable support for a running engine. It’s more challenging if that engine is driving a split-second mechanism activated by clutches, which requires stable anchoring.

The sapphire crystals in the front and on the exhibition case back reveal the intricate choreography of the dial-side mechanism.

Immediately recognizable are the two “Czapek” subdials. At 4 o’clock is a 30-minute totalizer, at 7 o’clock tick the small seconds.

In the center of the watch is the tripod bridge that holds down the patented satellite minute train and the split seconds-mechanism. Also clearly visible are the two column wheels needed for the chronograph and the split-seconds mechanisms respectively.

This latest iteration of the Antarctique is named “Ice Blue.” This model features traditionally blued hands that harmonise well with the weave of metallic greys inside the open-worked watch. A closer look reveals a fumé blue shimmer emanating from the minute track and the two totalizer tracks.

The effect is produced by the use of sapphire crystal rings that have been treated with metal oxides applied by an evaporation process. Adding to the visual dynamism of the dial is the red chrono hand, and the small red “60” at 12 o’clock.

Another salient visual aspect, though, is the dance of levers and cams on the dial of this split-second chronograph and the clamp, which instantly immobilizes one of the chrono wheels when the split-second pusher is activated. The other chronograph hand must then continue its time-counting undisturbed.

When the clamp is released, the immobilized hand will “catch up” (rattraper in French) to its companion. Each part must be manufactured to the highest specifications to ensure absolute precision.

Driving the Rattrapante Ice Blue is the Czapek’s high-performance proprietary caliber SHX6. It was created in collaboration with Chronode and is both a mechanical and aesthetic work of art. The split-second runs on energy tapped from the second wheel. It has a horizontal clutch rather than a vertical one to highlight the aesthetics of the transmission.

Furthermore, to ensure the streamlined look of the watch, the number of parts and their thickness was reduced to a minimum. Everything had to fit in the 42.5-millimeter case.

The Antarctique Rattrapante Ice Blue comes on Czapek’s own stainless steel case bracelet, whose links are shaped like the letter C.

It is a limited edition of 99 pieces.

Patek Philippe Ref. 5951P – Split-Seconds Monopusher Chronograph with Perpetual Calendar with Platinum Case and Black Dial

Legendary Swiss watch brand Patek Philippe presents new complication-Ref. 5951P, the thinnest split-seconds monopusher chronograph ever made with a perpetual calendar.

It is absolutely legitimate to assign Patek Philippe’s split-seconds or rattrapante chronographs to the category of Grand Complications which also includes minute repeaters, tourbillons, and particularly elaborate calendar mechanisms as well as astronomical functions.

The Ref. 5951P, which combines a split-seconds chronograph with a perpetual calendar, will therefore no doubt rank among the most exciting debuts at this year’s Baselworld show. The specifications imposed another challenge: the movement was to be as thin as possible.

Patek Philippe Split-seconds Monopusher Chronograph with Perpetual Calendar, Ref. 5951P

Patek Philippe’s CHR 27-525 PS basic caliber is already the thinnest column-wheel-controlled split-seconds chronograph movement, so it seemed appropriate that the perpetual calendar cadrature should be similarly discreet. The task was compounded by the fact that the movement has a diameter of only 27,3 mm.

Nonetheless, the workshops succeeded in designing a calendar module with a day/night display that indicates the date, day, month, leap year cycle, and moon phase yet measures only 2.05 mm from top to bottom. Together with the basic movement, this adds up to an overall height of just 7.3 mm, making the new Ref. 5951P the thinnest rattrapante chronograph with perpetual calendar ever crafted by Patek Philippe.

The outcome of this innovation is a perpetual calendar with a moon-phase display comprising 148 individual parts in a cadrature with a diameter of just 27,3 mm and a height of 2.05 mm. It controls a moon-phase display and an analog date as well as the day, the month, the day/night indication and the leap-year cycle in apertures.

This module with a perpetual calendar was developed expressly for the CHR 27-525 PS split-seconds chronograph movement launched in 2005 and now joins it in the new caliber CHR 27-525 PS Q. Due to its extreme complexity, this caliber is exclusively hand-crafted one by one.

Among its special features is the 60-minute chronograph counter driven via the cannon pinion, an ingenious construction that contributes significantly to the ultra-thin silhouette of the movement. Of course, the chronograph wheels of the caliber also have Patek Philippe’s patented tooth profiles that improve its efficiency, reduce friction, and boost functional reliability when the chronograph is engaged.

Its Gyromax balance wheel is fitted with a Breguet balance spring that breathes with a frequency of 21,600 semi-oscillations per hour (3 hertz). The chronograph’s start, stop, and reset commands are activated by a single in-crown pusher. Lap times are stopped with a rectangular push piece at 2 o’clock.

The design of the dial also proved to be a challenge. In a relatively small area, it delivers no fewer than 12 indications: three hands for standard time in hours, minutes, and seconds, three hands for the splitseconds chronograph functions, plus the day, month, date, leap-year cycle, moon phase, and day/night indication.

Despite the density of information that it provides, the sporty black dial of the Ref. 5951P is quickly and easily readable. The moon-phase display in the gracefully curved aperture at 12 o’clock deviates from the true lunar cycle by only one day in 122 years. Standard time is indicated with leaf-shaped white-gold hands and applied baton-style hour markers. For contrast, short-time measurements are tracked with red hands.

The fine tips of the chronograph and rattrapante hands follow a scale that precisely emulates the contour of the cushion shaped bezel. The subdial for the analog date is positioned at 6 o’clock flanked by round apertures for the day/night indicator and for the leap-year display.

For once, the years are indicated with Arabic rather than Roman numerals, emphasizing the modern, masculine style of this split-seconds chronograph. The days of the week are displayed in an aperture between the date scale and the seconds subdial, whereas the month aperture is symmetrically positioned on the 60-minute counter side.

With such a clear and aesthetic time and calendar data presentation, Patek Philippe demonstrates yet again that it tolerates no compromises, neither in functionality nor in design.

Patek Philippe 5951P
The Ref. 5951P has been endowed with a cushion shaped platinum case to accommodate its ultra-thin movement. It is reminiscent of the famous art-deco watches for which the manufacture received rave reviews in the 1920s and 1930s.

The rectangular rattrapante pusher in the side of the case at 2 o’clock – it is used to stop lap times – was also inspired by historic models. Next to it is the knurled crown which contains the pusher that controls the chronograph. The sapphire crystal glass duplicates the cushion shape of the case, a square form with curved sides.

The sapphire-crystal insert in the snap back has the same contour. It is a show window on a magnificent movement, revealing many hand-finished components, the elaborate rattrapante mechanism, and the rhythmic beat of the Gyromax balance wheel. It is a sight that will never bore the true watch enthusiast even though the ballet repeats itself infinitely.
