Louis Erard Excellence Guilloché Main Limited Edition

After the Excellence Émail Grand Feu watch, Louis Erard presents the Excellence Guilloché Main, a limited edition automatic timepiece featuring a hand-guilloché dial with 3D checked pattern. The dial hosts the signature fir tree hands in blued steel.

The dials of Louis Erard Excellence Guilloché Main watches are made piece by piece by hand guilloché, one of the most traditional artistic craftworks of all. The 3D checked pattern of the dial is inspired by the marble parquet of a Venetian High Renaissance palace, crossed with an engraving by M.C. Escher. They are made by the dial maker Fehr in La Chaux-de-Fonds. The pattern is carried out on a manual guilloché rose engine lathe: a century-old machine made of cams, feelers, cranks and chisels.

This geometric pattern tricks the eye by creating depth in an image that is perfectly flat. The effect is reinforced by the black varnish, used to cover the dial before the guilloché, and the final rhodium plating that gives a silver patina to the brass exposed by the chisel.

In this model, a limited edition of 99 pieces, Louis Erard combines tradition and contemporary watchmaking. The case is modern, sleek in polished steel, 42 millimetres, water-resistant to 50 metres and with a signature fir tree crown.

The strap is black calf nubuck leather with pin buckle. The automatic Sellita SW261-1 movement is visible from the open caseback.
