Omega's caliber 1894 is a recreation of the 19-ligne 'Omega' calibre which lend the brand its name. It is made using a mix of original components, including all of the bridges, mainplates, escapements and bimetallic balance spring, and new parts - such as the barrel, mainspring, jewels, bushings (in Sedna™ gold), axis & pinons, balance staff and wheels, and the entire winding mechanism.
