Chase Hattan Watches has dated this Vintage Omega Seamaster Watch to the 1960s.

This reference features the legendary Omega Calibre 552 automatic movement, housed in a 34mm stainless steel ALD-signed Dennison case (36mm with crown). Dennison, a respected British case manufacturer, produced cases for Omega during this era — ensuring compliance with UK import duties while maintaining Swiss quality standards. The combination of a Swiss-made Omega movement and a British Dennison case gives this watch added historical significance and collectability.
