Frequently asked questions

What is the lug width of the Patek Philippe Aquanaut 5650G-001?

The lug width of the Patek Philippe Aquanaut 5650G-001 is 21mm. This measurement is specific to the 40.80mm case and must be verified with a digital calliper, positioning the measurement between the inner lugs, shoulder to shoulder.

Which strap is most suitable for the Patek Philippe Aquanaut 5650G-001?

For the 5650G-001 in white gold, we recommend: black alligator with vegetable tanning (formal and neutral solution), medium brown calf with natural patina (warm contrast and character), or butadiene rubber for sports wear. The choice depends on primary usage and personal aesthetic preferences.

How do you correctly change the strap on a Patek Philippe Aquanaut 5650G-001?

Strap changing requires delicate tools: a spring bar removal tool, magnifying glass and calibrated movement. We recommend entrusting this operation to a specialised atelier such as Casati Milano, where the strap is fitted with manual precision and the case inspected for micro-abrasions.

Is an aftermarket strap compatible with the Patek Philippe Aquanaut 5650G-001?

Yes, any strap with a 21mm lug width is compatible with the 5650G-001. However, construction quality must be excellent to avoid compromising the aesthetic value and longevity of the watch. Milanostraps offers artisanal straps specifically selected for this measurement.

How long does a leather strap last on a Patek Philippe Aquanaut 5650G-001?

A quality leather strap (alligator or calf with vegetable tanning) typically lasts 3-5 years of daily wear, developing natural patina. Longevity depends on sun exposure, perspiration and humidity. Casati Milano guarantees 18 months against manufacturing defects and recommends annual maintenance with specific protective creams.
