Strap for Multi-Scale Chronograph 5975 Platinum / 175th Anniversary

The Patek Philippe Complications 5975P-001 features 20-millimetre lugs. This measurement represents the distance between the two pins that attach the strap to the case and determines compatibility with every aftermarket strap. To verify the correct measurement, use a digital calliper, inserting the point between the pins: the millimetre reading corresponds to your watch's lug width.

For a timepiece of this complexity, we recommend medium-brown alligator for timeless classicism, vegetable-tanned calf for those desiring natural patination over time, or NATO canvas for daily versatility. The choice depends on use: formal and collecting suggests alligator or calf; active and informal use favours technical strap or FKM rubber. Casati Milano provides personalised consultation in atelier to identify the material best suited to your wrist and habits.

Replacement requires removing the watch from its case and accessing the lug pins. Use a spring bar tool—a curved instrument specific to watches—to compress the spring pin, allowing its extraction from the case lug. Once the worn strap is removed, insert the pin into the new strap (verifying lug width is 20 mm), then reinsert the pin by compressing the spring into the case lug. A delicate operation: those less experienced may turn to Casati Milano for assisted strap change by appointment.

Yes. Any strap produced with 20 mm lug width is compatible with the 5975P-001. Milano Straps offers a collection of artisanal straps specifically calibrated to this width, manufactured in alligator, vegetable-tanned calf, shell cordovan and technical rubber. Casati Milano, a Milan-based bespoke atelier, produces custom straps tailored to personal aesthetic preference, with direct consultation on-site.

Lifespan depends on material and usage. Premium alligator resists 5-8 years with formal wear (2-3 wearings weekly); vegetable-tanned calf, more absorbent, may require replacement after 3-5 years of daily use, developing progressive patina that testifies to the object's history. FKM rubber maintains elasticity for 7-10 years under normal conditions. Casati Milano guarantees 18 months against manufacturing defects; natural leather wear—creasing, loss of shine—constitutes aesthetic process and falls within the logic of conscious luxury ageing.
