Inspired by the mid-century modern style of the 1950s and 60s, the Ellum is a beautifully crafted slim dress watch with vintage elements. The 40mm stainless steel case is assembled and tested for water-resistance of up to 100 meters. The navy dial has a vintage style domed shape with applied indices that curve with the dial. The brown Italian leather strap is fitted with quick release pins and is compatible with any Jack Mason 20mm strap. The Ellum features sapphire crystal and a Miyota 1L45 movement.
