Strap for Horological Machine N°6 Alien Nation HM6 Green

The lug width of the 60.STGL.B is precisely 20 mm. This dimension is determined by the biomorphic titanium case geometry and represents a specific construction standard for this model. Correct measurement is performed by positioning a ruler between the inner points of both lugs: the distance must correspond exactly to 20 mm to ensure proper strap installation.

The ideal strap for the 60.STGL.B depends on intended use. For absolute aesthetic excellence, alligator represents the recommended choice: the leather's natural grain dialogues elegantly with the case's biomechanical geometry. Vegetable-tanned calf offers an alternative that develops patina over time. For contemporary versatility, a technical canvas NATO ensures comfort without formal compromise, whilst structured rubber adapts to more dynamic applications.

Strap replacement is accomplished through lug removal from the case. Position the watch with the caseback facing upward and use a dedicated tool (spring bar tool) to gently compress the internal tension spring of the lug. Once compressed, the lug extracts from its seat. Reverse the procedure to install the new strap, ensuring lugs are completely inserted and locked into their seats.

Yes, numerous quality aftermarket straps are compatible with the 20 mm lug width of the 60.STGL.B. MilanoStraps offers a comprehensive selection of 20 mm straps in alligator, calf, vegetable tanning, NATO, and structured rubber, all crafted artisanally according to excellence standards. Compatibility is guaranteed by standardised lug width dimensions.

Leather strap longevity depends upon intensity of wear, climate conditions, and tanning quality. A superior alligator or calf strap, worn daily, maintains structural integrity for 3-5 years. With moderate use and proper care (avoid prolonged moisture, dry after accidental contact), longevity may extend considerably. Vegetable tanning naturally protects leather over time whilst developing protective patina.
