Girard-Perregaux Cat's Eye Day and Night 80488D52A751-CK6A Guide: Pink Gold, Diamonds, Mother-of-Pearl

The Girard-Perregaux Cat's Eye Day and Night 80488D52A751-CK6A is the pink gold, diamond-set version of GP's oval ladies' watch: a 35.40 x 30.40 mm case set with 80 brilliant-cut diamonds, a mother-of-pearl dial with a small seconds and an engraved pink gold day and night disc, and the in-house self-winding calibre GP03300 visible through a sapphire caseback, on a black alligator strap with a pink gold folding buckle. Bizak's catalogue lists it as "Date and Night"; Girard-Perregaux's name for the model is Day and Night, and the watch has no date. This guide covers the specifications from GP's own page, how the day and night display works, how the reference compares with the other Cat's Eye models in our catalogue, how it wears, retail and dealer price context on October 17, 2026, and what to check before buying. Bizak & Co. sources Girard-Perregaux to order; the Girard-Perregaux collection lists the references we can seek.

Girard-Perregaux Cat's Eye 80488D52A751-CK6A specifications

Source: the Girard-Perregaux product page for the 80488D52A751-CK6A, which lists the case size, thickness, diamond count, calibre and strap; the Cat's Eye collection page shows the current line-up. The Swiss made designation that GP uses is governed by the rules summarised by the Federation of the Swiss Watch Industry.

What does the Cat's Eye reference number mean?

Girard-Perregaux references are structured, and reading them helps when comparing catalogue entries. The first five digits identify the case and complication: 80488 is the Cat's Eye Day and Night, 80484 the Cat's Eye Small Seconds, 80496 the Cat's Eye Celestial with moon phases and 80498 the High Jewellery version. The next group describes the case material and setting: D indicates a diamond-set case, 52 is pink gold, 11 is steel and 53 is white gold. The following group identifies the dial, so A751 on this reference is the mother-of-pearl dial, while A451 on the sister model is blue aventurine. The final group is the strap and buckle; CK6A is black alligator with a pink gold folding buckle. Two references that differ only in the last group are the same watch on a different strap, which is worth knowing when a dealer quotes a price on a reference that looks unfamiliar.

How does the day and night display work?

The day and night indicator is a 24-hour display read against a rotating disc. On the Cat's Eye the disc is pink gold, engraved with alternating matt and polished surfaces so that the day and night halves read by texture and reflection rather than by paint. It turns once every 24 hours and shows whether the hour hand is pointing to morning or evening, which is the point of the complication: a mechanical watch with a 12-hour dial cannot otherwise tell 7 in the morning from 7 at night. On a dress watch it is as much decoration as function, and GP treats it that way, giving it a generous aperture on the mother-of-pearl dial alongside the small seconds. The calibre GP03300 driving it is GP's in-house 11 ½ ligne automatic, the same base used across the Cat's Eye line, running at 4 Hz with a minimum 46-hour reserve. It is visible through the sapphire caseback, with a pink gold rotor engraved with a pattern of GP logos.

80488D52A751-CK6A vs other Cat's Eye references: which to choose?

The Day and Night in pink gold is the most expensive non-jewellery Cat's Eye in our catalogue because it combines the gold case, the full diamond bezel and the complication. Three cheaper routes exist. The steel Day and Night "Lotus" keeps the same 80488 case and complication in steel with a decorated mother-of-pearl dial at roughly half the price. The pink gold Small Seconds keeps the gold, diamonds and mother-of-pearl and drops the day and night disc. The Celestial swaps the day and night display for a moon phase at a lower ask, and is the one to consider if the complication is the attraction. At the top, the white gold High Jewellery Plum Blossom is a different category of object.

How does the Cat's Eye Day and Night wear?

The oval case measures 35.40 mm along its longer axis and 30.40 mm across, and it is the across measurement that matters on the wrist: the watch sits like a 30 to 31 mm round watch in width while reading as larger because of the elongated bezel and the diamonds running its full length. At 11.29 mm it is not thin, a consequence of the automatic calibre and the domed crystal, but the short lugs and the supple alligator strap keep it close to the wrist. It suits wrists from about 14 cm (5.5 inches) upward and is easiest to wear with a cuff that can clear the diamonds. Mother-of-pearl shifts colour with the light and no two dials are identical, so two examples of the same reference can look slightly different side by side. The 30 m rating means the watch should be kept away from water; the strap and the pink gold buckle are not made for it either.

How much is a Girard-Perregaux Cat's Eye 80488D52A751-CK6A? Prices in 2026

• Retail. Girard-Perregaux publishes US pricing on its own product page, which displayed a figure in the low US$43,000s for the 80488D52A751-CK6A on October 17, 2026. The steel diamond-set Cat's Eye models sit well below that, and the High Jewellery references well above.
• Secondary market. Girard-Perregaux ladies' watches do not carry the waiting-list premiums of Rolex, Patek Philippe or Audemars Piguet. Unworn examples through dealers have asked at or below retail through 2025 and 2026, and pre-owned diamond-set Cat's Eye references have asked at a sizeable discount to retail, so condition and completeness matter more than scarcity.
• Bizak catalogue asks. On October 17, 2026 our sourced catalogue listed the 80488D52A751-CK6A at US$41,299 brand new, the steel Day and Night "Lotus" at US$22,499, the pink gold Celestial at US$29,999 and the pink gold Small Seconds at US$26,199, all sourced to order.

Those figures describe what we saw on one day and will move. Ask for a dated quote for the exact reference, strap and set. Our guides to Patek Philippe prices and Audemars Piguet prices explain how dealer asks for gold and gem-set watches are built, and the same logic applies here.

Is the Cat's Eye Day and Night a good investment?

No, in the sense that it is unlikely to be worth more than you paid for it in a few years, and that is true of almost every gold ladies' dress watch outside a handful of Patek Philippe and Cartier references. Buy it because the oval case, the diamonds and the day and night disc are what you want to wear, and because an in-house automatic with a five-year warranty is unusual at this size. The sensible financial move is to buy well: an unworn example below retail with the warranty registered and all accessories present will lose less than a boutique purchase, and a full set is far easier to sell later. If you expect to move it on, ask us for a written cash-buy view before you commit, and read our sell your watch page for how those offers work.

Buying a Cat's Eye 80488D52A751-CK6A: what to check

• Warranty registration. Girard-Perregaux's standard warranty can be extended to five years in total when the watch is registered; confirm whether the extension has been activated and in whose name, and insist on the warranty card.
• Diamond count and setting. The bezel carries 80 brilliant-cut diamonds, about 0.86 ct. Under a loupe each stone should sit level with its neighbours and the prongs should be intact; a replaced stone shows as a different brightness.
• Dial. Mother-of-pearl can craze or lift at the edges. Check the surface in raking light and confirm the day and night disc turns smoothly and reads correctly against the time set.
• Movement. The GP03300 should wind with the rotor and hold at least 46 hours off the wrist. Through the caseback, look for scratches on the rotor and bridges that indicate a non-GP opening.
• Case. Pink gold marks easily. Check the oval bezel edges and the caseback for polishing that has softened the lines, and look for stretched strap holes or a replaced non-GP strap.
• Buckle. The pink gold folding buckle should carry GP markings and match the case colour; a steel or generic buckle lowers the value.
• Set and accessories. Box, warranty card and any spare strap should accompany a brand new example. A price well below the band without a card is the single most reliable warning sign.

Quick answers

How much is a Girard-Perregaux Cat's Eye 80488D52A751-CK6A?

Girard-Perregaux's own US product page showed a price in the low US$43,000s on October 17, 2026. Bizak's sourced catalogue listed the reference at US$41,299 brand new on the same date, sourced to order.

What size is the Girard-Perregaux Cat's Eye?

The Day and Night case is oval, 35.40 mm long by 30.40 mm wide and 11.29 mm thick, so it wears like a 30 to 31 mm round watch in width while looking longer on the wrist.

What movement is in the Cat's Eye Day and Night?

The in-house self-winding calibre GP03300, with 218 parts, 32 jewels, a 4 Hz rate and a minimum 46-hour power reserve, visible through the sapphire caseback with a pink gold engraved rotor.

Does the Cat's Eye Day and Night have a date?

No. The complications are hours, minutes, small seconds and a 24-hour day and night disc. Some retailers list the model as "Date and Night", but that is a catalogue naming quirk rather than a function.

Is the Cat's Eye water resistant?

Only to 30 m, which covers splashes and hand washing. It should not be worn for swimming, and the alligator strap and gold buckle should be kept dry.
