The ARCEAU Grands Fonds

From Hermès Horloger 

Courtesy of Hermes

The basic watch design of the watch dates back to 1978 when Henri d’Origny brought forth the Arceau.

The movement is the Manufacture Hermès H1837 movement, which is mechanical, self-winding (that's automatic to you).

Courtesy of Hermes

What really sets the ARCEAU Grande Fonds apart is the dial.  The dial is described by  Hermès as glass mosaic.  

Courtesy of Hermes

Per Hermès, each dial takes a minimum of one month to create.  Per the release, there will be a grand total of 6 of these created, so if it's in your wheelhouse, don't dawdle ; )

The case is of white gold and measures 41 mm in diameter.
