Best answer


The calibre 504 was thefirst Omega Constellation calibre to carry the date function. The base calibre was the calibre 500, and, in keeping with Omega鈥檚 highly efficient interchangeable parts system, the calibre 504 was a confluence of parts from not only the 500 base calibre but also earlier calibres such as 240, 330, 344, 360, and 470.
