Habring² ChronoSport

Introduced in 2007, the HABRING² ChronoSport features legendary chronograph calibers such as Valjoux 7733 or the Valjoux 7734 movement.

Maria Kristina and Richard Habring decided to equip their new chronograph a historical movement that is no longer produced. This movement had to be equally as robust as any modern movement. The result is a limited series of the ChronoSport with alternatively either the Valjoux 7733 or the Valjoux 7734 movement.

With the ChronoSport, Maria Kristina and Richard Habring have succeeded in creating a modern chronograph with loving attention to technical finesse and tradition. The ChronoSport is reminiscent of the elegance of classic chronographs without being a mere copy. The ChronoSport has the advantage a clear dial, easy to read but not too plain. The size of the small indicator dials makes them easy to read.

The customer has the choice of three different dial-colours: galvanic black, galvanic blue or copper-tone. All three variants have applied rhodiated numbers and hour-markers which are coated with Superluminova in order to ensure easy legibility in the dark. The polished, rhodiated (rhodium-plated) baton hour and minute hands are also fitted with Superluminova.

The large three-part stainless steel case of the ChronoSport guarantees adequate protection for the movement. The doubly sealed massive stainless steel crown and the push-buttons are easy and safe to operate. And as Maria Kristina and Richard Habring deliberately chose to do without screw-locked buttons, it is possible to stop the time of any event at all times without any lengthy preparations. The sapphire crystal, reflection-free both inside and outside, ensures excellent legibility in all light conditions.

If the customer wishes, the ChronoSport can be fitted out with a black, blue or mother-of-pearl coloured strap made of micro-fibre so that the watch does not have to be taken off for aquatic sports. The micro-fibre strap is rubber-lined and therefore extremely hard-wearing. Alternatively the ChronoSport can be supplied with a stainless-steel strap.

A massive stainless-steel back is standard on the ChronoSport. It provides reliable protection for the movement at all times. Flexible production methods and customer-awareness at Habring2 make it possible to individualize the watch in accordance with the buyer’s wishes.

For the technically interested customer, who not only wants to tell the time or use the ChronoSport as a stop-watch but wants to be able to see the Valjoux calibre working, it is possible to refine the movement with an engraving. Maria Kristina and Richard Habring’s devotion to their handicraft is reflected in the decoration (refinement) of the movement. They sought a way to give their watches a unique appearance which would be recognized immediately by the connoisseur. They made no attempt to invent a “Wörthersee”-ribbing in order to resent the customer with a supposed innovative decorative engraving. Instead Habring sought inspiration from the traditional engraving handicraft of the region around Ferlach. With the intricate decorations found on hunting rifles in mind, Maria Kristina and Richard Habring, together with the Master Engraver and watch enthusiast Florian Güllert from Klagenfurt, developed the engraving for the “Carinthian” which can, if requested, be used on the ChronoSport.

If Maria Kristina and Richard Habring present a chronograph for everyday use, it must above all be robust and reliable. It is therefore only logical if they revert to an old chronograph caliber, a particularly robust and reliable movement, for their ChronoSport. Their decision to use the reputed Valjoux calibre 7733, which especially valued by experts for its quality and dependability, was understandable not only because of its excellent time-keeping qualities but also for its outstanding technical specification.

A bone of contention for many collectors is the so-called “Kulissenschaltung”, or cam-shift mechanism. In spite of its poor reputation, this mechanism is not only inexpensive to produce and to assemble, it also functions faultlessly, precisely and reliably. With this mechanism the function of the column wheel is replaced in the 7733 by a specially shaped cam-disc below the hammer, the so-called “Kulisse” or cam-shift. In technical terms, it fulfills the function of a curved cam-disc although it does not rotate but simply swivels slightly around its arbor.

Precisely calculated curves create protruding cams and pits into which the various levers of the chronograph mechanism engage. This determines whether the chronograph is activated, de-activated or stopped. In the Valjoux 7733 this cam-shift is riveted from below to the hammer and thus supports the function of the cam-disc. The hammer is shaped in such a way that it controls the function of the clutch by means of a small hatchet-shaped extension.

The great advantage of the cam-shift mechanism over the pillar wheel is of a mainly technical nature. Whereas the pillar wheel must be milled with great precision and almost always requires subsequent machining, the cam-shift can simply be stamped and so can be manufactured in quantity with constant precision and quality.

The tolerances are so minute that no subsequent machining is necessary. Should any deviations arise, they can easily be compensated by adjustment through the eccentric screws. Production costs can be further reduced by the springs which in most cases can also be pressed rather than having to be formed in a complex operation. Seen against this background it is clear that the development of the 7733 was a step in the right direction: wristwatches, including chronographs, were never status symbols, but timepieces.

The 7730 caliber family was by no means a completely new construction. The roots of this chronograph caliber are to be found with Venus SA, a firm which also belonged to the Ebauches SA. This manufacturer of watch movements specialized in the production of large-volume chronographs. Venus was taken over by Ebauches in 1966 and closed down. But some of the Venus calibers continued to be produced by the Valjoux SA firm, also part of the Ebauche group. In that way the modern Venus caliber 188 lived on as the Valjoux calibre 7730. With the introduction of the Valjoux 7730, the movement underwent constructive modernization.

The 7733 was fitted with a movable adjustable stud-holder so that it could be regulated better and more quickly. The small regulating-finger disappeared, as did the screw-balance too. For anyone looking at the 7733 the most obvious change was to the Chronograph bridge which had the shape of a very stable “V”. An even closer look would reveal the fact that the other bridges and the balance cock too had modified shapes.

An even closer look would show that changes had been made to the chronograph mechanism. First and foremost there is the re-shaping of the hammer. The two sides are now separated from the top and so give the cam-shift mechanism a more slender form. This technical modification has the advantage of enabling the minute-counter to be set at the zero-position. The sliding gear together with its toothed-wheel, which drives the minute-counter wheel, was also adapted. This improved engagement with the minute-counter wheel for which constant pressure is required – guaranteeing the reliable and faultless functioning of the 7733.

The most noticeable change on the dial side of the 7733 is the newly shaped setting-lever spring. It was necessary to reshape it because the 7733 has a spring-loaded setting-lever which makes it easier to install the winding-stem. But one technical detail of the caliber 7733 was maintained. It retained its classical amplitude of 18 000 A/h. Chronograph experts may well be surprised at this decision since at about the same time the much more traditional pillar-wheel caliber Valjour 23 and Valjoux 72 were adapted to 21 600 Ah.

Nevertheless, in spite of the slow beat of 2.5 Hertz, the Valjoux 7733 keeps remarkably good time. The 7733 and 7734 calibers had a standard 30-minute register but they could also be supplied with a 45-minute register. HABRING²’s ChronoSport is available with the 45-minute version only. The advantage of this for the ChronoSport is that the wearer can make better all-round use of his chronograph. For example, the football fan can stop a whole half of the match. He can then read off the added-time without having to make any calculations.

The ChronoSport, like all the other HABRING² watches, comes in a three-part wooden case made of brushed and oiled Oregon Pine. This case has an integrated drawer for spare-parts and contains a set of spares. Should the wearer wish to take off his ChronoSport when travelling, he can place the watch in a micro-fibre travel case which is included in the delivery. This travel-case is something special too. It is fastened with a reserve strap for the ChronoSport – an unusual feature which has the tremendous advantage of ensuring that ChronoSport never has to go without a reserve strap.
