Strap for Calatrava 5077 White Gold / Portrait of Flowers

The lug width of the Patek Philippe Calatrava 5077/100G-036 is 20 mm. This measurement represents the internal distance between the two spring bars that connect the strap to the case. Any compatible strap must measure exactly 20 mm in width to ensure precise fitting and perfect alignment with the case.

For the Calatrava 5077/100G-036 in white gold, we recommend alligator with vegetable tanning (brown or black) or Hermès or Taurillon calf leather. Alligator offers a natural geometric texture that ages beautifully; calf leather ensures softness and chromatic versatility. Shell cordovan is a bold choice that emphasises the lustre of white gold, but requires careful maintenance.

The strap is changed by extracting the spring bars that connect the strap to the case. A dedicated tool (spring bar tool) is required to compress the internal springs of the bars and extract the old strap. It is advisable to entrust this operation to a professional to avoid damage to the bars or case. Each new 20 mm lug width strap is installed simply by pushing the bars into their respective openings.

Any strap with a 20 mm lug width is compatible with the Calatrava 5077/100G-036. You can choose from hundreds of artisanal options: alligator, calf leather, shell cordovan, FKM rubber, fine fabrics. The important thing is to verify that the width of the buckle or clasp matches the aesthetics of the case, without weighing down the wrist profile.

A quality leather strap (alligator, calf, shell cordovan) lasts an average of 3-5 years with daily use, provided it receives basic maintenance: gentle cleaning, protection from excessive moisture, regular drying. Vegetable tanned leather tends to age better, developing patina. A bespoke strap crafted in the workshop has a sturdier structure and can exceed 6-7 years of intensive use.
