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).

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

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.
