Girard-Perregaux Puts New GP4800 Automatic in the Laureato FIFTY
Girard-Perregaux installed a new in-house automatic, calibre GP4800, in the Laureato FIFTY in October 2025. The 200-piece steel-and-3N-yellow-gold limited edition marks 50 years of the Laureato, which first appeared in 1975 as an integrated-bracelet luxury sports watch. According to WatchPro, the movement was developed entirely in-house and is displayed through a sapphire caseback.
What the GP4800 Specifies
Monochrome Watches listed the calibre at 25.60 mm in diameter and 4.28 mm thick, with 163 components and 19 jewels. It beats at 28,800 vibrations per hour, or 4 Hz, and stores about 55 hours of running time. The construction uses a silicon escapement, a variable-inertia balance, and ceramic-bearing automatic winding. A 3N gold rotor sits on rhodium-plated bridges finished with Côtes de Genève and diamond-bevelled edges. Visible architecture emphasises symmetry, with a skeletonised balance bridge under a full bridge and an openworked oscillating weight that carries arrow-shaped motifs.
Those figures sit in a 39 mm case that is 9.8 mm thick and water-resistant to 150 metres. The grey Clous de Paris dial uses gold indexes, a date window at 3 o’clock, and a central seconds hand with the GP double-arrow counterweight. Bracelet links were shortened relative to the 2016-generation Laureato, and the triple-folding clasp gained up to 4 mm of fine adjustment. WatchPro quoted a European list of €28,100; Monochrome recorded CHF 25,000 for the same limited run.

Where It Fits the 2025–2026 Cadence
The GP4800 is not a one-watch calibre. Girard-Perregaux had already framed it as a next-generation automatic with a silicon escapement before the FIFTY launch. In June 2026, Monochrome reported that the Laureato Fifty collection expanded into 39 mm and 36 mm steel models that continued to use GP4800. For readers mapping 4 Hz beat rates and silicon regulating parts onto more accessible platforms, see our notes on watch movement frequency and silicon hairsprings and anti-magnetic specs.
The 1975 Laureato sat among the first integrated luxury sports watches, arriving three years after the Royal Oak and a year before the Nautilus. According to Monochrome, later generations moved from quartz to the ultra-thin automatic 3000 in 1995, then through the 2003 Evo3 and the 2016 redesign. The FIFTY keeps that 2016 silhouette while shrinking the case to 39 mm and raising water resistance. The movement, rather than a new complication, is the technical headline: silicon, ceramic bearings, and a gold rotor in a 4.28 mm stack.
- October 2025: Laureato FIFTY limited to 200 pieces, two-tone, GP4800 debut in that case.
- Reference 81008-63-3412-1CM, 39 mm × 9.8 mm, 150 m.
- June 2026: steel Fifty line extends GP4800 into 36 mm and 39 mm regular sizes.
FAQ
Is GP4800 exclusive to the 200-piece FIFTY?
No. The FIFTY was the high-visibility launch vehicle. Later Fifty steel models in 2026 continued to house the same calibre, according to Monochrome Watches.
How does 55 hours compare with other 2025 automatics?
It sits in the mid range. Louis Vuitton’s LFT MA01.01, launched the same year, is listed at 45 hours; Bianchet’s UT01 flying-tourbillon automatic is listed at 60 hours.
What does the silicon escapement change in practice?
Silicon parts are used to reduce magnetic sensitivity and lubrication needs at the pallet and escape wheel. The brand still quotes a conventional 4 Hz rate rather than a higher-frequency silicon oscillator.
According to WatchPro (7 October 2025) and Monochrome Watches (7 October 2025; 4 June 2026).
