The Omega Constellation calibre 751 collection was powered by the last great series of high-value movements manufactured by Omega before the onset of the Swiss Crisis of the mid-1970s. The day-date calibre 751 can trace its origins back to the famous chronometer calibre 551 and is every bit as good as its mid-500 calibre siblings. And judging by the number of enquiries I receive about these Omega Constellation models, interest in collecting them is increasing.
As the prices of calibre 551, 561 and 564 Constellations, particularly Pie Pan models, continues to rise, new and often younger collectors are entering the field and taking a shine to the calibre 751 Constellation collection. These models represent an affordable entry point into the world of collecting chronometer grade watches.
