Blancpain’s Ladybird Colors Zodiaque puts the twelve signs of the Western zodiac on a rotating disc inside a 34.9mm gold case. The disc jumps on the exact day each sign changes, driven by the date itself.
I keep coming back to the restraint of the layout, because four indications share one dial and each one still gets a separate field. Off-centred hours and minutes sit low, the date arcs along the top edge, and the month runs retrograde on its own subdial.
Blancpain ties the idea to its calendar history, from complete, annual and perpetual calendars to the moon phase it has treated as a signature since 1983.
The Western zodiac behind it comes from Greco-Roman astrology, twelve signs tied to set periods of the year, from Aries through Pisces.
A new calibre built around sign changes
Calibre 2653QZ packs 362 components into a movement 5.37mm thick, with a differential linking the zodiac disc to the date and an annual cam tracking signs that last 30 to 32 days.
The cam decides each transition date, and the disc jumps instantly when that day arrives, so Scorpio gives way to Sagittarius overnight rather than creeping across a scale.
Off-centred timekeeping frees the dial’s upper half for the calendar, and that trade shapes the whole watch, since a centred layout would crowd four displays into one circle.
Blancpain’s secured movement lets every calendar correction happen safely at any time, without risk to the calibre.
A silicon balance spring and 38 jewels sit inside the spec sheet, and the movement runs at 4Hz behind a sapphire back.
The reserve runs 68 hours.
Nacre perlée and 133 diamonds share the light
The dial is nacre perlée, a mother-of-pearl grade harvested from the most curved central section of selected cultured shells, and each shell yields a single dial, under 2% of its usable pearl.
Two interlaced diamond circles frame the time and month displays, and bevelled gold rings pull back so the stones read larger than their settings.
Diamonds continue across the bezel and onto the buckle, 133 stones in total at 2.21 carats, in F-G colour and IF-VVS clarity.
Roman numerals and the twelve signs print in powdered silver or gold over a midnight-blue disc, and the contrast keeps the zodiac arc readable at a glance.
Weigh the specification against the stones and the watch stays a calendar piece at heart, its jewellery supporting the mechanism instead of replacing it.
No two dials catch light alike.
Cases come in red gold as reference 3664 2954 55A or white gold as 3664 1954 55A, both on alligator leather with a pin buckle, and water resistance sits at 3 bar. Case thickness is 10.80mm, with an 18mm lug width and a sapphire back.
Both gold versions share the same 34.90mm case and the same calibre, so the choice between them comes down to metal and dial tone.
