Today's offering showcases this fabulous avante-garde "Emerald" De Ville watch, inspired by the designs that Andrew Grima created for Omega and introduced in 1971.

"Grima, who was arguably his generation's foremost jeweler, counted Queen Elisabeth II among his clients. The Emerald line is distinguished by the generous proportions of its emerald-cut crystals of precious stone, quartz or mineral glass.

Initially, the pieces were reserved for the top of the Constellation range but as the Emerald line was extended, they were increasingly seen in the De Ville line. The Emerald line was only produced at OMEGA until 1973 but it left a lasting impression. Though a lost line at OMEGA these watches remain a "Premiere" collection today showing just how good the design was." - via Omega Museum.

Its emerald cut crystal protects its distinctive dial.

All parts are fully Omega down to the original special crystal! It presents in gorgeous restored condition.

The case presents as mint. Originally, the case top on this watch would have been gold plated, although Omega also made these watches in all steel.

The royal blue dial has been painstakingly restored - the printing could pass as Omega factory done to the naked eye.

Note that the dial is a rich true royal blue. Our photos couldn't do it justice.

As part of the restoration the fine original ultra thin Omega movement has just been serviced by a Master Watchmaker. It is running very strong and true, keeping time on par with a brand new Omega in our testing position.

For the finishing touch it has been equipped with a brand new calfskin leather strap meticulously detailed it making it ready for immediate enjoyment.

Included with the purchase is a one-year warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.

Andrew Grima:
Mr. Grima was honoured with an impressive array of prizes 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, at about the same time he was designing for Omega he was appointed jeweller to Her Majesty the Queen. He was commissioned by Omega to create a highly aesthetic avant-garde collection. Grima was given a free hand and chose to stick to one principle: he would create the watch around the dial, no matter what its form or dimension.

His work is carried on by his wife and daughter. The Grima website can be found here:
