Strap for Reverso Tribute Calendar Pink Gold / Silver / Alligator

The Reverso 3912420 has a lug width of 22 millimetres. This dimension corresponds to the space between the two lugs on the case and represents an intermediate standard within the Reverso family, allowing versatility in strap selection without compromising the proportional balance of the rectangular case.

For the pink gold Reverso 3912420, we recommend alligator leather with vegetable tanning (cognac or natural brown) for harmonious colour pairing, or black shell cordovan for a sober, contemporary contrast. Both develop a natural patina that mirrors the ageing of pink gold, creating aesthetic continuity over time.

The strap is changed by inserting a flat tool (a dedicated spring bar tool or small screwdriver) into the lateral holes situated beneath the case lugs. With gentle upward pressure, the lateral pins release and the previous strap slides away. Align the new strap's holes with the lug shoulders and press gently until you feel the click of engagement. If uncertain, consult a qualified watchmaker.

Yes. Any quality commercial strap with 22mm lug width is geometrically compatible with the 3912420. Compatibility is guaranteed by ISO standardisation. However, for a watch of this material and historical stature, we recommend artisanal leather straps (alligator, cordovan, calf) rather than mass-produced alternatives, to preserve the watch's aesthetic and temporal value.

Durability depends on intensity of use, climate, and leather quality. An artisanal alligator or shell cordovan strap, with ordinary care, lasts 5–8 years. Standard calf leather resists 3–5 years. Vegetable-tanned leather ages better than chrome-tanned leather, developing patina rather than deteriorating. Casati Milano guarantees 18 months against manufacturing defects; the rest depends on maintenance (occasional cleaning, drying after rain, seasonal rest).
