Patek Philippe
Complications 5230G-013— lug 20mm

The Patek Philippe Complications 5230G-013 features a lug width of 20 millimetres. This specification is the standard that Patek Philippe has adopted for Complications models with a 38.50 mm case diameter, ensuring harmonious proportions between the case and strap. To verify compatibility, measure the distance between the inner edges of the lugs with a digital calliper.

For this model, we recommend alligator in cognac-brown or dark brown tones, a material that naturally complements the sunburst blue dial. Alternatively, shell cordovan offers superior density and a patina that evolves over time. For formal occasions, vegetable-tanned calf leather represents a versatile and refined solution. A black alligator strap imparts austerity, enhancing the technical complexity of the timepiece.

Strap replacement requires a spring bar tool and a stable work surface. Position the watch face-down on a soft base. Insert the tool tip into the upper lug hole, push downwards to disengage the spring, and extract the spring bar. Repeat for the opposite side. Insert the new spring bars into the new strap, then reposition the watch. If you are uncertain about the procedure, entrust the task to an official Patek Philippe service centre.

Yes, provided the strap features 20 millimetre lugs. Bespoke straps crafted by Casati Milano are constructed specifically for this width, ensuring a geometrically perfect transition between case and strap. Always verify the manufacturer's technical specifications before purchase. The quality of construction and material selection significantly influence the final aesthetic and durability over time.

A quality leather strap, such as those crafted by Casati Milano, typically lasts 4–7 years with daily use, varying according to frequency of wear, climatic conditions, and sun exposure. Alligator and shell cordovan, denser materials, achieve longer lifespans thanks to their fibrous structure. The 18-month warranty on manufacturing defects covers any construction-related issues. A well-maintained strap, protected from excessive moisture and cleaned regularly, extends its operational lifespan considerably.
