Strap for Portugieser Regulateur Tourbillon Rose Gold / Silver

The lug width is 22mm. This dimension is specific to the 44mm case and ensures correct positioning of the strap relative to the watch's lugs. Measurement is taken from the inner base of one lug to the other, perpendicular to the case—not along its curve.

Mississippi alligator in cognac burnt tone is the choice that best enhances 18kt rose gold. The fine, natural grain of this material dialogues perfectly with the case's chromatic warmth without competing with it. Alternatively, a burgundy shell cordovan or vegetable-tanned calf leather offer elegance and noble ageing.

Strap change occurs via spring bars—the small metal tubes connecting the strap to the case lugs. Using a dedicated spring bar tool, apply gentle pressure to compress the spring and slide the bar out of its seat. Remove the old strap and insert the new one, aligning its holes with the lug shoulders. The operation requires care to avoid scratching the rose gold case.

Yes. Any strap with a 22mm lug width is compatible. Bespoke leather straps from Milano Straps are available in numerous leathers (alligator, calf, shell cordovan) and colours. The key is selecting construction quality that matches the watch's level: premium leather, impeccable stitching, and refined finishing.

A quality leather strap with vegetable tanning typically lasts 3–5 years with daily wear. Longevity depends on humidity, frequency of wear, maintenance, and leather type. Shell cordovan and alligator age better than standard calf. Regular maintenance—cleaning and complete drying after saltwater exposure—significantly extends strap life.
