Omega Constellation Ladies Watch 27 mm: Now With Co-Axial Caliber 8521 Ladies watch / Swiss Watches

Omega’s dressy line of Constellation timekeepers has recently been updated with a super-compact model that now packs their high-grade Omega Co-Axial Calibre 8521 automatic movement into a diminutive 27 mm rose gold case. Although some may find this particular Omega Constellation ref. 123.55.27.20.57.001 model with its loads of gold, gold-colored mother-of-pearl and a set of huge diamonds as blingy as a wedding gift from Tutankhamun himself, it surely looks great in its own daring way.




Offering a system of highly efficient bi-directional winding, as well as a free sprung-balance system that features an ultra-light-weight (and also antimagnetic) silicon balance spring, the movement has been here for a while (we, for example, saw this tiny engine in the last year’s Omega Ladymatic DeVille line of ladies watch.)

First introduced almost four years ago during Baselworld 2008 event, the original Caliber 8520 that this mechanism is based on was a sort of statement that Omega is here to be among the precious few who lead the way, not among the many who just refinish old (and boring) calibers from ETA.

Although the last year’s Ladymatic was offered in a comparatively large rose gold body whole 34 millimeters in diameter, it was clear by the look of its dial that the movement was designed for smaller cases: its date window was closer to the center of the dial than the 11 diamonds that served as hour markers.

This new piece is a living proof that the device was originally designed to power sub-30 mm timekeepers… like this Omega Constellation ref. 123.55.27.20.57.001.

The refreshed line is available in more than three dozens of variations, but this particular version with reference number 123.55.27.20.57.001 looks the most appealing to me.

Coming in a compact, tonneau-shaped body only 27 millimeters in diameter, the watch features an elegant mix of a mirror polished bezel, which is expertly paved with 32 full-cut diamonds that have a total weight of 0.50 carat, and brushed surfaces of the case and elegant bracelet, too, crafted from red gold.

But what makes this device the most attractive is, of course, the dial that features a piece of unique gold-tinted mother-of-pearl. While not looking too intrusive, the dial offers an adequate level of contrast for the polished hands that feature thin patches of white Superluminova on them.

As usual, the dial is set with 11 single-cut diamonds that tip the scales at 0.12 carats and (finally) belong to the same circle as the date window.
