In brief
Setting the date on a 611 means running the hands round past midnight — there is no quickset, which was normal enough for hand-wound watches at the end of the 1950s. The eccentric regulator comes from the 601; the date work is what makes this a separate calibre.
Short history
Nothing about the 611 was meant to impress, and it never needed to be: Omega made it in quantity for the Genève and De Ville. Its architecture is not strictly its own either, since the 6xx calibres carry bridges, wheels and much of the jewelling drawn from the automatic 5xx range. That trimmed the parts list at the factory, and it now lets a watchmaker raid one family to repair the other. Omega closed the manual line in 1974, quartz having already taken the Swiss market.
