Calatrava 6000G-001— lug 19mm

The Calatrava 6000G-001 features a lug width of 19 millimetres. This dimensional specification, inherited from the 1932 Calatrava 96, maintains the proportional balance between the 37 mm case and the leather strap. Verify that your chosen strap measures exactly 19 mm in width (tolerance ±0.3 mm for rigorous artisanal manufacturing).

Alligator in dark brown or black remains the reference material: its regular texture and natural patina development over time reflect the evolution of the white gold case. Shell cordovan with vegetable tanning represents the prestige alternative for those preferring finer grain and cognac tones. Vegetable-tanned calf leather offers superior durability and develops a grey-blue patina that creates striking contrast with white gold.

Use a spring bar tool with a 1.5 mm diameter tip. Insert the tool's point into the horizontal hole beneath the lug, apply gentle upward pressure until the spring retracts, then remove the old strap. Repeat symmetrically on the opposite lug. Slide the new strap into the lug holes until you hear a click indicating secure placement. If uncertain, entrust the operation to Casati Milano.

Yes, provided that the strap has a certified lug width of 19 millimetres. Milanostraps supplies a dedicated collection of compatible artisanal straps, crafted from premium materials (alligator, shell cordovan, calf leather) and fitted with deployante clasps in steel or white gold. Avoid generic 20 mm straps: they would disrupt the case proportions.

An alligator or vegetable-tanned calf strap typically lasts 3 to 5 years with daily wear, depending on climate (humidity accelerates ageing), frequency of use and maintenance. Shell cordovan tends to last 2 to 4 years if exposed to humidity. Casati Milano offers an 18-month warranty on manufacturing defects and reduced-cost clasp or keeper replacement within five years.
