Patek Philippe
Grand Complications 5004G-013— lug 20mm

The lug width of the Patek Philippe 5004G-013 is 20 mm. This measurement represents the distance between the pins that anchor the strap to the case. To verify compatibility, measure the space between the two metal cylinders on the case lugs using a digital calliper. Precise measurement is essential to avoid purchasing errors.

For the 5004G-013 in white gold, we recommend black or chocolate brown alligator for a classical aesthetic. Alligator offers uniform fine grain that does not compete visually with the case, ensuring discreet elegance. If you prefer a more contemporary look, vegetable-tanned calf develops authentic patina over years. For sporty use, a technical canvas NATO maintains formal rigour. Your final choice depends on intended use: formal, daily wear, or safe-kept.

To change the strap, obtain two small tools: a spring bar remover or a very thin screwdriver. Position the watch face-up on a soft surface. Locate the pin on the first lug, apply the tool into the small slot to push the pin towards the centre, then extract the old strap from the seat. Insert the new strap aligning the hole with the pin, reposition the pin into its seat and ensure it is firmly secured. Repeat for the opposite lug. Avoid excessive force: a Patek Philippe deserves care.

Yes, provided the strap has the correct 20 mm lug width. However, aftermarket strap quality must be consistent with the watch's value. Artisanal straps in alligator, calf or shell cordovan from specialised suppliers guarantee mechanical strength and aesthetics worthy of a Grand Complications. Avoid synthetic materials or universal shop straps: a Patek Philippe merits tailored craftsmanship and noble leathers.

Leather strap durability depends on material, usage and maintenance. Quality alligator, with moderate daily use, lasts 4-6 years before showing significant wear. Vegetable-tanned calf has similar longevity (4-7 years) but develops fascinating patina over time. Shell cordovan can last 8-10 years thanks to its natural hardness. To extend strap life, avoid prolonged water and direct UV exposure, and consider rotating between multiple straps if wearing the watch daily.
