Name: Girard-Perregaux Laureato 38mm 81005-11-431-11A
Brand: Girard-Perregaux
SKU: 81005-11-431-11A

The Laureato predates the Royal Oak by a year and gets far less credit for it. This 38mm steel reissue brings the original 1975 integrated-bracelet design back in a wearable modern package, powered by GP's own movement. It is one of the most underappreciated entries in the integrated-bracelet category.

What it is

Luigi Macaluso designed the original Laureato in 1975, giving Girard-Perregaux an integrated steel bracelet sport watch before the category had a name. The octagonal bezel was a deliberate design statement, distinct from the AP Royal Oak's porthole geometry yet equally bold for its time. The line was eventually retired as quartz and shifting tastes made steel sport watches a harder sell in the 1980s and 1990s.

GP revived the Laureato in 2016 for the brand's 225th anniversary, reintroducing it with in-house movements and updated case finishing. The 38mm reference sits at the accessible end of the modern range and is the closest thing to the spirit of the original.

Buying notes

The bracelet finishing on early production examples from 2016 and 2017 can show wear faster than expected on the brushed center links. Confirm the bracelet has not been polished by a jeweler, which destroys the alternating finish contrast. The clasp on the 38mm has been reported as slightly less refined than the 42mm version, so check engagement and play before buying.

The dial lacquer on some steel references picks up light differently depending on the angle, which photographs poorly but looks fine in person. Finally, verify the reference number carefully: 81005-11-431-11A is steel with a silver dial, and there are similar references with slightly different finishes that can be confused in secondary market listings.

Market read

The 38mm Laureato trades at a modest discount to retail on the secondary market, which is unusual for an in-house integrated-bracelet watch from a maison of this age. That gap exists primarily because GP does not have the same marketing pull as AP or PP, not because the watch is lesser. For a buyer who values movement quality and historical lineage over brand recognition, this is a genuine opportunity.

Prices have been stable rather than speculative, which makes it easier to buy at fair value.

Service expectations

The GP03300-0054 is a fully in-house automatic caliber with a 46-hour power reserve, serviced exclusively through Girard-Perregaux authorized service centers or qualified independent watchmakers with GP parts access. Service intervals are typically recommended at 5 to 7 years. Parts availability is good for a watch still in current production.

Authentication

The octagonal bezel finishing is the fastest authentication check on any Laureato.

Known issues in the market

Used Laureato examples frequently have polished cases that have softened the sharp transitions between brushed flanks and polished top surfaces.
Original factory finishing has very crisp right-angle edges at every brushed-to-polished transition; any rounding indicates case work.

Area	What to check	What is correct	Red flag
case	Octagonal bezel brushed-to-polished transitions	Crisp right-angle edges where brushed flanks meet polished top surfaces on each octagonal facet	Rounded or blended transitions; softened edges from buffing or repolishing
bracelet	Integrated bracelet seating at lug interface	Bracelet meets the case with zero gap and no lateral movement; links are Girard-Perregaux signed	Any gap at the lug interface or lateral play; unsigned or aftermarket end-links
caseback	Exhibition caseback showing Cal. GP03300-0054	GP-decorated bridges visible; movement text includes GP caliber designation	Non-GP movement visible; solid caseback substituted for exhibition caseback

Common legitimate replacements

Repolished cases are common on pre-owned Laureatos; sharp octagonal edge loss reduces value significantly.
Aftermarket bracelets exist; verify end-link signing before purchase.

Last reviewed June 2026

The Laureato 38mm is the most accessible entry into the integrated-bracelet trio of 1975, but the octagonal bezel with eight polished screws is an exacting detail that replicas consistently get wrong. Count the screws. Check the facets.

Known reproduction risks

toggle

MEDIUM

Replicas of the Laureato exist but are produced in smaller volumes than Royal Oak or Nautilus replicas. The most common tell is the wrong screw count or placement on the bezel.

Bezel screw count other than exactly 8, or screws positioned at face midpoints rather than corners
Bracelet that does not taper from case to clasp, or links without the alternating brushed/polished finish
Case height that does not match the slim 10.7mm profile of the genuine 38mm
Exhibition caseback movement that does not show the GP03300 layout

The 38mm case size is less commonly replicated than the 42mm. Most Laureato replicas target the 42mm market; a stated 38mm with off-spec proportions should be verified against measurements.

Octagonal bezel

Original: The defining element: an octagonal bezel with 8 polished decorative screws, one at each flat-to-flat corner. Each screw head is polished, matching the polished facets on the bezel. The bezel itself alternates brushed and polished surfaces.

Replacement tells

Fewer than 8 screws on the bezel, or any screws not at exact corner positions
Screw heads that are flat or brushed rather than polished
Bezel facets with inconsistent finish transitions between brushed and polished surfaces
Octagonal shape that is slightly irregular or asymmetric when viewed dead-on

Integrated bracelet

Original: The bracelet tapers continuously from the case and shares finishing language with the case itself: brushed central links flanked by polished outer links. The fold-over clasp should be signed and finished to the same standard.

Replacement tells

Bracelet links that do not taper from case to clasp, indicating a non-original aftermarket strap or bracelet
Clasp without "Girard-Perregaux" or "GP" signing on the inner face
Link finishing that is fully brushed or fully polished without the alternating pattern
Any rattle or looseness in the bracelet links inconsistent with a well-maintained original

Dial

Original: The sunburst brushed dial has a directional grain that catches light from one orientation only. Applied indices should sit at a consistent height relative to the dial plane. The date aperture is integrated cleanly with no visible raw edge around the opening.

Replacement tells

Dial surface with an omnidirectional or circular brushed finish, which indicates a non-original or refinished dial
Applied indices with inconsistent shadow depth or any loose index that moves under gentle pressure
Date aperture with a visible raw machined edge or irregular border

Movement tells

toggle

Cal. GP03300-0054 runs at 28,800bph with a 54-hour power reserve from a single mainspring. A well-wound Laureato 38 should comfortably reach 50+ hours before stopping.
Côtes de Genève striping on the movement plates should be parallel and evenly spaced. Under a loupe, each stripe should have a consistent width and flat-polished surface between the grooves.
The rotor on Cal. GP03300-0054 is typically engraved with the GP crest or a decorative pattern. A plain or unsigned rotor is a service indicator.
Movement bevels on the bridges and plates should show hand-chamfered edges with slight variability in width, consistent with finishing by hand. Machine-chamfered bevels are perfectly uniform.
