Eberhard & Co. Chrono 4 Géant Full Injection

Eberhard Chrono 4 Geant Full InjectionEberhard & Co. has joined the “all-black” watch party with a new, limited-edition version of its well-known Chrono 4 Géant, nicknamed “Full Injection,” released ahead of the 2013 Baselworld watch fair in April.

The watch gets its name — and its sleek, dark, “stealth” look — from the special treatment used to harden the 46-mm steel case. The process, an advanced low-temperature carbon diffusion, allows the “injected” carbon to penetrate the steel for 30 micrometers to produce a structural hardening. The result is a marked improvement in the case’s wear-resistance and fatigue limit. The black coloring comes from the use of a DLC (Diamond-Like Coating) treatment called Dianoir, which is used on the case, bezel, crown, chronograph push-buttons, and buckle.

The dial is also black, with black chronograph subdials (arranged in a horizontal line as per the Chrono 4’s patented design) and red hands for the chrono counters and central seconds. The dial has a circular metal plate with a côtes de Genève pattern, a tachymeter scale on the flange, and applied luminescent indices. The center-mounted hands are sword-shaped and partially skeletonized.

The case is 14.1 mm thick and is water-resistant to 200 meters. Its caseback, on which is engraved the words “Full Injection,” is affixed by eight screws. The screw-down crown, which is protected by a crown guard, is adorned with a bas-relief Eberhard & Co. shield. The push-buttons also screw down, and the bezel, which has six black PVD-treated screws and black engraved numerals, turns in one direction in the style of a professional divers’ watch. The strap is made from black rubber and has a vertically sculpted motif and a bas-relief Eberhard “E” shield.

Eberhard’s automatic chronograph movement, Caliber EB.250, built on a ETA 2894 base movement, powers the watch and its four counters, which display, from left to right, the chronograph minutes and hours, the time on a 24-hour scale, and the running seconds. The date appears in a window at 12 o’clock. The Chrono 4 Géant Full Injection will be produced in a limited series of 500 pieces. (Photo can be enlarged with a click.)

  1. If the chronograph complication is their work, then setting it on an ETA 2894 top or COSC grade movement will make a reliable watch. It will not have the lasting prestige or cachet of Patek Philippe, A. Lange & Sohne, IWC, Ulysse Nardin, Rolex or any manufacturer of haute horolgie that does all work in house. And I don’t see the attraction of Limited Production design variations just to market a very busy existing design by defusing in some carbon to toughen a case. It is bling from the get-go and therefore most likely ephemeral. To each his own.
    Swatch Group, owner of ETA, is making a bid in Swiss courts to limit their movement sales, I suppose to limit competition against their marques by boutique houses who use ETA movements. Maybe sooner than later Eberhard and others must come up with new suppliers or in-house designs. Gone are the days of loyalty to this or that Swiss house by an ebuache manufacturer. This is especially true now that Swatch Group owns Nivarox FAR maker of balance springs and complete timing kits, the heart of any mechanical watch. We must respect the Hayek’s (Swatch Group) goal of limiting their technology and ebauches to their brands.
    I do feel the most desirable watches are those built in the marque’s atelier. The old manual wind Omega Speedmasters are good examples of great watches with lasting cachet.

  2. thanks for all the updates.
    help me if I”m wrong,but i think ETA is the new swayer in the watch industry.that makes me beck the question “if you cant buy the patek,AP,a lange ect like most of us cant,”what is the use of new watches each year?new face same movement.
