Patek Philippe
Calatrava 5153G-001— lug 18mm

The lug width of the Patek Philippe Calatrava 5153G-001 is 18 mm. This measurement refers to the distance between the two strap attachment points, measured internally. For your watch, it is essential to verify this dimension before ordering a strap, particularly with custom models, to ensure a perfect fit without lateral play.

An alligator leather strap is the most natural choice for the 5153G-001: its regular texture dialogues elegantly with the white gold case, without competing for attention. A dark brown, black or anthracite grey alligator offers a noble contrast. Alternatively, vegetable-tanned calf leather or shell cordovan (paired with a handmade deployant clasp) provide even greater refinement, developing a natural patina over time.

To change the strap on the 5153G-001, you will need a specialised tool (spring bar tool) to remove the horizontal pins (spring bars) that secure the strap to the lugs. Position the watch with the lugs facing upwards, insert the spring bar tool into the space between the lug and the strap, lift gently until the pin is released, then slide the strap downwards. To fit the new strap, repeat the process in reverse. If you lack experience, consult a professional watchmaker.

Yes, it is possible to fit a high-quality artisanal aftermarket strap, provided the lug width is exactly 18 mm. A custom strap in alligator, calf or shell cordovan will not compromise the watch's value and allows authentic personalisation. We recommend choosing noble materials and manual craftsmanship that align with the quality of the watch itself.

A natural leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily wear, provided it is properly maintained. Factors such as frequency of wear, climate, sun exposure and care affect longevity. Vegetable-tanned leather develops a natural patina that improves with time. High-quality artisanal straps can extend durability to 7-8 years. We recommend gently cleaning the strap every 2-3 months and storing the watch in a dry environment when not in use.
