Up for sale is this very rare and well preserved 1947 Omega Calatrava with a Dennison made stainless steel case sold to the civilian market. The 33.5 mm by 40mm case is in wonderful condition and is outfitted with the original domed acrylic crystal.


The Omega caliber 30T2 PC manual wind movement is keeping excellent time, and the original unsigned crown winds buttery smooth. Omega did not start signing crowns until approximately late 1947 to 1950, and this may very well be one of the last Omega’s without a signed crown. The production date of this piece is two years after World War II officially ended, but the military pedigree of the stylistic aspects of this piece is undeniable.


The 30T2 movement was used by Omega starting in 1939 and ending in 1963 and featured a Breguet hairspring. The robust 15 jewel movement featured a 44-hour power reserve and was regarded as being highly reliable and was the cornerstone of Omega issued military timepieces.


One can only venture a guess that the dial in hands were intended to be placed on British Military issued pieces towards the end of the war. The distinct Arabic numerals and the syringe style hour and minute hands have deep tones of matching almond radium aged to perfection. The natural and consistent patina of the dial complements the subtle but distinct black outline of the numerals making the dial highly legible. The 6 o’clock sub seconds dial has aged amazingly to a slightly different tone to the dial, but nearly matching the aging of the patina on the numerals, making it further more legible.


This gorgeous and rare piece is being offered on an 18 mm Bonklip style bracelet, further complementing the military inspired designs of this piece. Finding civilian issued military style pieces is becoming increasingly more difficult especially with well-known brands like Omega, and this British produced Dennison case is an excellent example we are very proud to offer.
