A larger and less common sibling to the oval shape Geneve Dynamic line most collectors are familiar with, these square case Geneve and De Ville models were produced for over a decade and have a style and variety of dial options entirely unique to themselves.

A Pair of Massive Squares

The Geneve & De Ville Dynamic square cases are a very substantial piece of 1970's eccentricity with a very unique style and presence and a variety of funky dials to make them really desirable.

These giant square case models get lost among the modular Dynamic case models, are often mislabeled and misunderstood and get overlooked for their round case cousin, but these are in my view more worth exploring.

The Dynamic family are interesting in that they came out of the 1960's as a relatively affordable sporty watch and sold well enough that the final versions of the De Ville Dynamic were still being made even in 1979.  This is despite the fact that several new generations of watches and movements had come out during that decade.

The Dynamic name would be revived in the 80's with a rather forgettable second generation bearing the Seamaster name, and a much better third generation in the 1990's.  These original models, born out of Omega's golden era though, are fondly remembered by collectors for their quality, style and flair.
