Strap for Flagship 38.5 Two Tone / White

The lug width is 20 mm. This measurement identifies the internal space between the case lugs and determines strap compatibility. It is measured with a calliper by positioning the tips between the outer edge of one lug and the outer edge of the opposite lug on the same side of the case.

For the Flagship, we recommend alligator or shell cordovan for formal occasions, vegetable-tanned calf for elegant daily wear, and FKM rubber or NATO for sports use. The choice depends on frequency of wear and context: the Flagship deserves investment in a handcrafted strap for durability and controlled patina development.

Strap change is performed using springbars located in the internal holes of the lugs. Position a flat tool under the bar to compress it slightly, remove the old strap, and insert the bar into the hole of the new strap until it clicks into place. No specialised tools are required; many wearers use a pen opener or dedicated tool.

Yes, all straps with 20 mm lug width are compatible. On milanostraps.it you will find handcrafted straps certified to DIN standards for ±0.5 mm tolerance, customisable in leather, colour, length and stitching thread. The Casati Milano atelier also offers bespoke custom straps.

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts 3–5 years with daily wear, developing aesthetic patina over time. Longevity depends on UV exposure, humidity and care: avoid prolonged salt water exposure and apply protective balm every 6–12 months. The Casati Milano atelier guarantees 18 months on handcrafted straps.
