Patek Philippe
Complications 5396G-011— lug 20mm

The lug width of the Patek Philippe Complications 5396G-011 is 20 millimetres. This measurement is specific to this reference and represents the internal distance between the lugs at the case level. All compatible straps must rigorously respect this width to ensure a perfect fit with the lugs and balanced weight distribution on the wrist.

For this white gold timepiece, the ideal choice is a high-quality alligator leather strap, which reflects the refinement of the case and the complexity of the calibre 324 S QA LU 24H/303 movement. Alternatively, superior-grade calf leather offers immediate softness and a naturally evolving patina over time. For more sporty applications, a 100% cotton NATO with a silk-lined edge provides versatility without compromising the watch's elegance.

To change the strap, you will need a specific lug pin removal tool, available in standard watchmaking kits. Position the watch on a soft, stable surface, locate the pin that runs laterally through the lug, carefully unscrew or remove the pin using the tool, then remove the old strap. Insert the new strap into the lug and reinsert the pin, tightening with moderate pressure. If you lack experience, consult a professional to avoid damaging the white gold case or lugs.

Yes, you may use aftermarket compatible straps provided they strictly respect the 20-millimetre width specification and are crafted from superior materials. Specialist artisanal brands such as Casati Milano supply certified straps for this reference, manufactured from alligator, calf leather, and other premium materials. The essential point is to verify compatibility with the model-specific lugs and select straps produced by professionals who understand the construction characteristics of a watch in this category.

A superior-quality leather strap, such as alligator or fine calf, has an average lifespan of 4 to 7 years with regular use and proper maintenance. Longevity depends on factors including sun exposure, humidity, frequency of wear, and applied care. An alligator strap with natural vegetable tanning develops a fascinating patina over time, becoming increasingly characterful. The standard Casati Milano warranty covers manufacturing defects for 18 months; thereafter, we recommend professional servicing of the stitching and reinforcement of the fibres.
