130 chimes that mark the history of Eberhard & Co., but well over 130 snapshots that immortalise the values and creations which throughout the years since 1887 – when the company was founded by Georges-Lucien Eberhard in La Chaux-de-Fonds – have made up the DNA of the Swiss watchmakers whose name has become synonymous with tradition, constant research and innovation.
Featuring a new 42 mm Ø case framed by a bezel with circular satin finish; the crown, personalised with the number “130”, is positioned between the two drop-shaped chronograph buttons. Three dial variants are available:

• grey with 4 grey counters with azure finishing and details in orange
• argenté with 4 black counters with azurée finishing and details in blue
• black with 4 black counters with azurée finishing and details in orange

In all versions, the central soleil part of the dial is delimited by a diamantage-finished circle, while luminescent indices are applied on the outer azurée zone. Waterproof to 50 m, the case-back of the Chrono 4 130 is secured by 8 screws and features a central medallion in bas-relief with sandblast finish, personalised with the CHRONO 4 130 logo, where the 4 is raised. The model comes with a grey-black carbon wear strap.
Consist of 130 pieces to celebrate the anniversary of the Maison, a Chrono 4 in a very refined version. The steel case has the same dimensions as the standard edition but it houses a skeleton dial, argenté or black, which reveals the main plate and the wheels with DLC® finishing, protected by an upper bridge in a special sapphire glass that is 3 tenths of a millimetre thick, an element of highly complex construction.

A rhodium plaque, secured to the main plate by two screws, shows the name of the model and the historic trademark of Eberhard & Co., as used for the first wrist chronograph in 1919. The sapphire glass case-back provides a view of the circular oscillating weight, finished with Côtes de Genève and customised with the number 130. This edition also comes with a grey-black carbon-wear strap. A magnificent piece of watchmaking that emphasises the Maison’s pride in its historical heritage.
