Patek Philippe
Twenty~4 4908/200G-011

The Patek Philippe Twenty~4 4908/200G-011 features a lug width (ansa width) of 18 millimetres. This measurement is determined by the distance between the two spring bar holes located on the shoulders of the rectangular case. The 18 mm width was specifically chosen by Patek Philippe to maintain optimal proportions relative to the case diameter (24 mm), ensuring the strap does not visually overwhelm the watch. When purchasing a replacement strap, always verify it is designed for the 18 mm lug width.

The choice depends on intended usage, but alligator leather in vegetable tannage is considered the reference standard for this model. Alligator preserves the timeless elegance of white gold and develops a noble patina that ages beautifully. Alternatively, shell cordovan offers extraordinary colour depth and acquires natural lustre through wear. Box calf in neutral tones (black, dark brown, cream white) is the most versatile and practical solution for daily use, maintaining aesthetic coherence with the precious case.

The strap of the 4908/200G-011 is removable via spring bars (perni) that connect the case lugs to the strap ends. Using a specialised spring bar tool, gently depress the bar to release tension and free the old strap. It is advisable to perform this operation on a soft surface to prevent scratches on the gold case. If you lack experience, consult a professional watchmaker or Casati Milano, where specialist technicians will replace the strap with precision and care.

Any strap with an 18 mm lug width is mechanically compatible with the 4908/200G-011. However, to preserve the aesthetic integrity of the watch, we recommend selecting straps crafted from noble materials (alligator, shell cordovan, quality calf) with finishes coherent to the Twenty~4's minimalist style. Avoid straps that are excessively thick or feature ornate buckles, as these may diminish the design's purity. On milanostraps.it, you will find a curated selection of 18 mm compatible straps.

The lifespan of a leather strap depends on material quality and usage patterns. A quality alligator or shell cordovan strap, with ordinary care, may last 3–5 years of daily wear. Box calf, being softer, typically exhibits visible wear (creasing, edge deterioration) after 2–3 years. Factors such as perspiration exposure, moisture, and sunlight exposure accelerate ageing. A strap is not a permanent component; rather, the beauty of genuine leather lies in its evolution over time. The Casati Milano warranty (18 months on manufacturing defects) covers construction issues, not natural wear.
