A very rare example of the Omega De Ville designed the legendary Andrew Grima. The Crystal is in perfect condition as is the lovely silver dial.  Both are flawless for a watch approaching 55 years old.  
Andrew Grima was awarded many honours including twelve Diamonds-International Awards. He was the first jeweller to win the Queen's Award for Export in 1966 and is the only jeweller to have won the Duke of Edinburgh Prize for Elegant Design.
In 1970, around the same time that he was designing for Omega, he was appointed jeweller to Her Majesty the Queen .
Omega commissioned him to create an avant-garde collection with great aesthetics.
Andrew was given carte blanche and chose to stick to one principle: he would create the watch around the dial, regardless of its shape.  Queen Elizabeth II owned an Andrew Grima designed Omega
This watch is one of a number I purchased from an estate.  The 1 previous owner lived in Singapore in the 1970's and travelled extensively during which he'd buy watches and put in a safe.  
The watch has a very unusual long rectangular design, in which the cut of the crystal matches the case shape perfectly. The integration of the bracelet is also incredibly well executed, as the case smoothly runs over into the bracelet.  The strap is made from White Gold (filled) - see photos of hallmark - and sets off the watch brilliantly.
