Edox Grand Ocean Calibre 27000 Ladies Watch Ladies watch / Quartz watches / Swiss Watches

The Swiss watchmaker Edox has recently started selling its new Edox Grand Ocean Calibre 27000 (ref. 357JN NID) quartz ladies watch, which is equipped with the thinnest in its class calendar movement. The most interesting thing about this new mechanism, is that Edox claims to have developed it using its own resources.


The movement in question –the Edox Calibre 27000 quartz caliber— is only 1.40 mm thick and holds the title of the thinnest among its direct competitors.

For example, Ronda’s thinnest caliber in their Slimtech collection, too, measures the same 1.4 millimeters top to bottom, but its functionality is limited to just displaying hours and minutes, opt in for a simple calendar, and you get the caliber’s thickness increased by half a millimeter. Not that it matters much in the grand scheme of things, but it is still nice to have a relatively affordable Swiss made watch that is the best in something!

Of course, only time will tell how reliable this mechanism will be in the longer term.


Thanks to the use of such a thin movement, the timekeeper’s 33 mm case is only 3.20 mm thick.

I am pretty sure that lots of ladies who ever considered buying a nice sporty timekeeper were turned off by their relatively thick case. This one, thanks to its impressive thinness, will make an almost perfect accessory even for a person with a very skinny wrist.

What’s even more pleasant is that Edox’s designers managed to successfully and almost impeccably adapt Grand Ocean‘s signature styling to this ultra-slim model without losing a single bit of the original line’s boldness and beauty.

The secret here is obviously the very thin notched bezel that -thanks to its profile- look rugged and strong while not increasing the timepiece’s overall thickness much.

Even the ultra-small setting crown doesn’t detract too much from the Grand Ocean’s spirit of adventure, although, personally, I would prefer to see its diameter increased by 0.5 mm or so.

Of course, in terms of craftsmanship and ingenuity the watch doesn’t even come close to the real wonders of Swiss mechanical watchmaking, but, unlike some other contenders, it doesn’t try to fool you pretending that it is. In fact, it makes it explicitly clear that this is just an accessory, not some piece of high horology.


Thanks to the chosen color scheme, the dial of this new Edox Grand Ocean 27000 offers very good legibility even when the light is not very good. Of course, given its sporty styling, it would be also nice to have at least thin strips of Superluminova applied to its hour and minute hands, but the lack of the luminous compound doesn’t look like a deal breaker to me.


Lume or no lume, this version of the Edox Grand Ocean family may be an ideal choice for those seeking a watch, which is both sporty, elegant and combines high accuracy of a premium quartz caliber with moderate pricing. At this moment, the Swiss-based brand plans to sell this beautiful trinket for about €990.
