Developed over more than three years, McGonigle’s Ogma features a 39.3 mm steel case and the in-house, manually wound McG01 calibre, with 186 components, 38 jewels and a 90-hour power reserve. A differential drives the dial-side power-reserve indicator. Frances McGonigle hand-engraves the barrel bridge in tribute to Irish deity Ogma. Water resistance is 50 metres.
