Strap for Glycine Airman Double Twelve Black / Stainless Steel

The lug width of the Glycine Airman 3938.19.LB9B is 22 millimetres. This measurement is the distance between the two lugs that attach the strap to the case and is essential for ensuring complete compatibility with any aftermarket strap. All straps sold by Milano Straps in the 22mm category will fit securely and precisely.

The best strap depends on intended use. For aesthetic coherence with aviation tradition, vegetable-tanned Tuscan leather is the ideal choice: it ages naturally and develops a beautiful patina. For frequent flight operations or humid environments, FKM rubber (Viton) offers durability and resistance to degradation. For a versatile and historically authentic solution, a NATO strap in dyed cotton maintains the practice of military pilots. An alligator leather strap represents the luxury option, with pronounced texture and exceptional longevity.

Changing the strap takes only a few minutes and requires no specialised tools. Observing the case from the rear, you will notice two small metal lugs that hold the strap at the ends (one on each side). With firm but controlled pressure on these lugs, the strap disengages from the case. The new strap is inserted by aligning the holes with the lugs and pushing until it clicks into position. If you prefer to avoid the risk of accidental scratching, any watchmaker can perform the service in minutes.

Yes, any strap with a 22mm lug width is mechanically compatible. However, it is important to consider aesthetics and function: straps that are too thick may emphasise the already substantial case diameter, whilst very thin straps may appear disproportionate. Milano Straps offers curated selections of 22mm straps that respect the visual proportions of the Airman, ensuring both mechanical compatibility and aesthetic harmony.

A quality vegetable-tanned Tuscan leather strap, worn daily with reasonable care, typically lasts 3–5 years before requiring replacement. Durability depends on sun exposure, humidity, weekly wear frequency, and maintenance (light cleaning, drying after wetting). FKM rubber lasts longer, up to 7–10 years, as it does not degrade biologically. A shell cordovan strap, if available, can last even longer thanks to the natural density of horse leather.
