AN UNIQUE GRÖNEFELD PARALLAX IN PLATINUM

In October 2014 the horological brother Bart and Tim Grönefeld were laureated by the international jury of the Grand Prix d’Horlogerie de Genève. The Parallax Tourbillon was awarded “best tourbillon” in its class.

The Grönefeld Parallax Tourbillon features a “flying” tourbillon with a large central seconds hand, stop seconds, a power reserve- and winding-setting mechanism indicator. The hand finished movement displays sophistication and craftsmanship at the very highest level.

FLYING TOURBILLON

Well-designed and impeccably executed tourbillons are particularly accurate timekeepers. The flying tourbillon allows full appreciation of the concentric, rhythmic “breathing” of the balance hairspring, while ensuring high precision.

Bart and Tim Grönefeld further highlighted the tourbillon by raising it out of the movement and above the dial. As with the immaculately finished movement bridges, the tourbillon cage is crafted in stainless steel. Three days are required just for the hand finishing of the tourbillon components.

LARGE CENTRAL SECONDS

The precision of the Parallax Tourbillon is evidenced by the large central seconds hand. Normally a central seconds hand requires a friction spring to prevent small fluttering caused by play in the gear train.

For the Parallax Tourbillon, the Grönefeld brothers developed the movement with an added pinion and wheel so that the energy-sapping friction spring is not required: A feature improving power transfer to the regulator and contributing to the precision and impressive power reserve of 72-hours.

PUSH-ONLY CROWN AND FUNCTION INDICATOR

In addition to the flying tourbillon and friction-spring-free central seconds, the Parallax Tourbillon has yet another innovative feature: rather than pulling the crown to set the time, which has the risk of damaging the fragile crown stem, it is pressed.

An indicator on the dial displays the function selected: “W” for Winding or “S” for time setting. When the time setting function is selected, both tourbillon cage bridge and the central seconds hand automatically return to their respective 12 o’clock positions and stop (or hack) while the time is set.

STAINLESS STEEL BRIDGES

For this unique piece Bart and Tim Grönefeld made special blackened stainless steel bridges for this unique movement to enhance the contrast. As well as the superior hardness and durability of stainless steel compared to standard brass or nickel, the metal absolutely gleams when polished to a mirror finish. And as stainless steel does not oxidize, the gleaming finish lasts and lasts.

GRÖNEFELD HISTORY

The Grönefeld family has a history spanning for more than a hundred years in watchmaking. Bart and Tim Grönefeld are the third generation to continue the family tradition, which was founded by Johan Grönefeld in 1912. After a long career working for the most prestigious Swiss watch manufacturers, the Grönefeld brothers presented their first watch, a Tourbillon Minute Repeater, in 2008. They followed this in 2010 with their award-winning One Hertz, first in-house developed caliber. Grönefeld timepieces stand out for the innovation of their technical features, the clarity of their design and the excellence of their craftsmanship.

Eterna – Royal KonTiki Chronograph

















ETERNAAdventure Royal KonTiki Chronograph NEW

Click on the mouse wheel to see the large size ...               BIG FOTO







































LEGENDARY PREDECESSORS AND MANUFACTURING EXCELLENCE

As the name suggests, the Royal KonTiki Chronograph is born of a long line of illustrious predecessors which have characterised Eterna’s collections for decades.

Like those, it is highly functional, reliable, robust and tough. However, it would not be doing justice to this new time- piece to reduce it simply to these attributes: after all, the movement ticking away inside the chronograph is an innovative development by Eterna itself and there- fore worthy of special attention.

This new Royal KonTiki model is one of the first chrono- graphs from Eterna to have a movement that the compa- ny has manufactured itself. Because of the revolutionary modular nature of the Eterna basic movement 39, it has been possible to add a self-winding mechanism, a chronograph with flyback function and a date display to create the calibre 3916A.

Its outstanding accuracy as a chronometer, together with the guaranteed 65-hour power reserve, make the Royal KonTiki Chronograph a reliable partner at all times for modern adventurers and individualists.


Strong, masculine appearance

Entirely in keeping with its fabled predecessors from Eterna, the new Royal KonTiki Chronograph is charac- terised by a strong, masculine design. The robust, 42.55 mm stainless steel case, optionally also available with black PVD coating, creates an impression of strength at first sight. This is due primarily to the entirely unmis- takeable bezel. Its main features are the pronounced circular elements and five black PVD-coated screws arranged in the shape of the famous Eterna logo. The chronograph buttons are also coated with black rubber for ease of use, while the crown protector is made of blackened steel. The watch embodies strength, mecha- nical perfection and accuracy.

Different levels create interesting tension in the harmo- nious dial which has been kept a restrained anthracite colour. The discreet engraved sunburst motif in the centre, the 30-minute and 12-hour timer at 3 o’clock, the little seconds display at 9 o’clock and the date window at 6 o’clock are enclosed within a raised ring, while the silver-coloured centres of the subdials are slightly recessed.

The applied, white SuperLuminova-coated hour indices and the striking, similarly luminescent hour and minute hands stand out boldly against the dial to guarantee outstanding legibility. Additional contrast is created by the tips of the chronograph hands, which have been dipped in luminescent red. The silver-colou- red numerals on the two subdials and the date display stand out starkly against their black backgrounds and are perfectly legible even in poor light conditions.
