Strap for Albishorn Marinagraph Classic

The Albishorn Marinagraph Classic features a lug width (misura ansa) of precisely 20 millimetres. This measurement refers to the distance between the pins traversing the two lateral lugs of the case and determines strap compatibility. It is crucial to distinguish this measurement from the case diameter (39mm in this instance): two independent parameters requiring separate verification.

There is no singular optimal choice; rather, selection depends upon intended use. A vegetable-tanned alligator strap provides formal elegance and aesthetic ageing; calf leather offers daily tactile softness; shell cordovan represents a long-term investment with evolving patina; NATO fabric ensures practicality and rapid interchange; fluoroelastomeric rubber guarantees technical performance and moisture-resistant properties. The 39mm case diameter with 20mm lug width accommodates all these proposals without aesthetic imbalance.

Strap replacement occurs via two removable spring pins. Utilising a dedicated spring bar tool or sterilised needle, vertical pressure is applied to compress the internal spring mechanism, permitting horizontal withdrawal from the lugs. This procedure is repeated on the second pin. Subsequently, the new strap is inserted by aligning the holes with the pins and releasing pressure. The operation requires only minutes and no specialist technical expertise.

Yes, all straps with 20 millimetre lug width are mechanically compatible. Verification concerns exclusively the pin diameter and the width of the securing passage. We recommend confirming with the manufacturer that the chosen strap tolerates the weight of the stainless steel case and ALB01 movement without subsequent loosening. Premium material straps maintain stability even following months of intensive use.

Durability depends upon frequency of use and tanning method. A vegetable-tanned calf strap used daily resists degradation for 18-36 months before replacement becomes necessary. Alligator leather persists 24-48 months owing to more robust fibrous structure. Shell cordovan exceeds 5 years with proper maintenance (semi-annual conditioning with neutral creams). NATO textile straps demonstrate superior durability, 3-5 years, limited primarily by fibre fatigue and colour fading. Fluoroelastomeric rubber maintains mechanical properties for 4-6 years prior to natural rigidification.
