Strap for Portugieser Perpetual Calendar 44 White Gold / Ice Blue

The lug width is 22mm. This dimension is specific to this model and does not correspond to the more common standard sizes (20mm or 24mm). It is essential to measure precisely using a digital calliper, as a slightly wider or narrower lug width would not fit correctly into the case lugs.

Dark brown alligator (mahogany tone) is the most natural choice for this white gold timepiece: the grainy texture pairs discreetly with the precious metal, and the patina it acquires over time conveys authenticity. Shell cordovan offers an alternative of depth, whilst vegetable-tanned calf provides a contemporary proposal whilst maintaining aesthetic dignity.

Position the watch with the lugs facing towards you. Use a spring bar removal tool to push the elastic pin situated beneath the lug, lifting the lug itself. Once the old strap is removed, insert the new one by aligning the lugs in the corresponding holes and press until you hear the pin reposition with a click. If unsure, consult a trusted jeweller.

Yes, any 22mm strap is mechanically compatible. However, it is crucial that the material and construction quality reflect the value of the watch: premium leather such as alligator, shell cordovan or tinted calf preserve the watch's authority, whilst economical materials diminish its character.

A quality leather strap (alligator, shell cordovan, calf) typically lasts 3–5 years with regular use and proper maintenance. Longevity depends on humidity, sun exposure and frequency of wear. Vegetable-tanned leather naturally evolves towards richer patina, extending visual lifespan beyond 5 years. The 18-month warranty on Casati Milano custom straps covers any manufacturing defects.
