The present Omega Constellation Grand Luxe in rose gold was at the time of its production by far the most expensive model of Omega’s line. Made in 1958, it did not only feature the legendary observatory tested calibre 505 but also the incredibly well made Grand Luxe gold bracelet imitating the shape of a hand finished leather strap. The dial, adorned with four diamonds, is rather unusual as the Omega’s signature is applied below the centre. Knowing that a large portion of the Grand Luxe’s production was sold to royal families in the Middle East it is possible that the large blank space on the upper half of the dial was originally reserved for either a portrait or the signature of the country’s ruler.The specimen offer here for sale is in overall very good condition and still features the original period crystal, recognisable by the microscopic Omega symbol placed in the centre.
