Strap for Portugieser Perpetual Calendar 5021 Luis Figo Rose Gold / Black

The lug width of the Portugieser IW5021-20 is 22mm. This measurement was selected by IWC to maintain visual balance on a 44.2mm diameter case. To verify strap compatibility, measure the distance between the inside of the lugs with a digital calliper: a 22mm lug width accommodates straps measuring between 21.8 and 22.2mm.

The best strap for the Portugieser is Mississippi alligator, particularly in the Havana Deep tone. The straight grain and regular scutes of alligator echo the rational architecture of the dial and rose gold. A vegetable-tanned calf strap in Cognac or Tobacco represents an excellent alternative for those preferring softness and stratified texture. NATO straps are discouraged for a watch of this calibre.

To change the strap: 1) Remove the watch from your wrist and position it on a soft surface; 2) Locate the two lugs at 12 and 6 o'clock; 3) Use a spring bar tool or dedicated removal tool to gently push the pin upwards from the bottom, freeing the old strap; 4) Align the new strap (22mm width) with the lugs and reinsert the pins. Avoid excessive force: the pins are rose gold and require precision, not brute strength.

The Portugieser IW5021-20 accepts all straps with 22mm lug width. Milano Straps offers online a selection of alligator, vegetable-tanned calf, rubber, and shell cordovan in 22mm, customisable in dimensions, initials, and thread colour. For bespoke experience, Casati Milano atelier allows personal selection of hides, WhatsApp updates, and 18-month warranty. Compatibility is guaranteed only with genuine 22mm lugs: beware of straps advertised as 'universal'.

A high-quality natural leather strap (alligator, vegetable-tanned calf, shell cordovan) lasts on average 3-5 years with regular daily wear. Durability depends on: humidity and climate conditions, frequency of wear, strap care (drying after rain, avoiding excessive perspiration). Mississippi alligator tends to last longer than calf due to fibre density. Casati Milano atelier offers 18-month warranty on bespoke straps, and replacement of the stitching thread at reduced cost.
