The Laureato 81010-11-433-11A, seen from the bench

The Girard-Perregaux Laureato 42 Automatic Stainless Steel Green Eternity Edition (ref. 81010-11-433-11A) features a 42mm octagonal stainless steel case with a GP01800-0008 movement combining hours, minutes, seconds and date. The 27mm lug width is critical for strap compatibility and must be measured precisely at the case lugs. This contemporary reinterpretation maintains the proportions of Gérald Genta's 1970s integrated watch design, with brushed stainless steel finish, guilloché dial, and light water resistance for daily wear.

Frequently asked questions

What is the lug width of the Girard-Perregaux Laureato 81010-11-433-11A?

The lug width is 27 mm, measured orthogonally between the case attachment pins. Accurate measurement with a digital calliper, excluding the case shoulder, is essential to ensure complete compatibility with aftermarket straps.

Which strap pairs best with the Laureato 81010-11-433-11A?

Genuine alligator or Belgian shell cordovan represent the highest aesthetic coherence, respecting the geometric sophistication of the original design. For daily wear, vegetable-tanned calf leather or cotton NATO offer versatility whilst maintaining stylistic rigour.

How do you change the strap on a Girard-Perregaux Laureato?

The operation requires a spring bar tool. Insert the tool into the lateral spaces of the pin, applying gentle pressure to release the internal spring. Extract the pin fully, remove the old strap and position the new one, reinserting the pin until the safety click engages. We recommend verification at Casati Milano atelier.

Is an aftermarket strap from Milano Straps compatible with the 81010-11-433-11A?

Yes, provided the strap is dimensioned for a 27 mm lug attachment. Milano Straps manufactures straps in various lug widths, guaranteeing structural compatibility. Measurement verification at Casati Milano atelier is advisable to exclude millimetre variations from case wear.

How long does a leather strap last on a Laureato timepiece?

Genuine alligator or shell cordovan strap, used daily with rotation, typically lasts 4–6 years before replacement. Vegetable-tanned calf offers 3–5 years of wear, developing aesthetic patina over time. Longevity depends on solar exposure, humidity and frequency of use.
