Atlas type guide

Hunter, half-hunter and open-face watches

In the nineteenth century the pocket watch case settled into a few standard forms. The hunter (French savonnette) has a hinged front lid protecting the crystal — reputedly for riders who could not risk broken glass — and is opened by pressing the crown or a push-piece. The half-hunter has a small window in the lid so the hands can be read when closed. The open-face (lépine) watch has no front cover, with the crown at 12; hunters normally carry the crown at 3.

Case types also changed with winding: key-wound watches gave way to keyless (stem-wound) mechanisms after Adrien Philippe's and others' designs of the 1840s, with pendant setting or lever setting.
