Omega Aqua Terra Jewellery Co-Axial Ladies Watch in Rose Gold Ladies watch / Swiss Watches

Released yearly this year, the 2010 Omega Aqua Terra Jewellery Co-Axial 150M (ref. 231.55.39.21.51.001) ladies watch is available in a great number of choices. However, the most imposing of them all is the one in a 38.5 mm rose gold case and on bracelet crafted of the same noble metal.




The Omega Aqua Terra Jewellery Co-Axial is powered by the relatively new Omega caliber 8501 automatic movement that was officially revealed in January, 2007.

The caliber is built solely in-house and features Omega’s proprietary co-axial escapement technology, which makes the watch more durable compared to those sporting traditional lever escapement.

Comprising 202 components, the movement sports a two-barrel design that ensures as long as 60 hours of continuous operation.

All Omega 8501 calibers are meticulously decorated and are equipped with 18-carat rose gold winding rotors and balance bridges. This is a nice touch, since in this particular watch the tiny engine is perfectly visible through the polished screw-in sapphire crystal case-back.

The 38.5 mm Aqua Terra case comes equipped with a rose gold bezel set with 52 full-cut diamonds.

The theme of precious stones is further supported with eleven more single-cut diamonds that mark the hours.

Although the hour indexes lack any lume whatsoever, there is a certain amount of Superluminova covering the hour and minute hands, which makes the watch usable in total darkness.

What I really like about Omega, is that they are always serious about how their hands look. This particular model features facetted 18 Ct gold hands with diamond-polished sides and brushed tops that the Aqua Terra line is famous for.

The watch is sold either on a black alligator leather strap with a foldover clasp, or a brushed 18 Ct gold bracelet with Omega’s patented screw-and-pin system and a safety clasp, which seems to be more appropriate for this gorgeous timekeeping accessory.

With its expected recommended street price (prediction based on a similar model with different dial finish) of approximately $40,000 USD this is definitely not something a normal enthusiast would buy on an impulse. Still, with the sort of high-grade movement the brand used to animate the piece and the sheer amount of diamonds and gold used to craft this beauty, I would say that the price is well-justified.
