Strap for Royal KonTiki Chronograph GMT

The Eterna Adventure 7760.42.80.0280 is fitted with 22mm lugs. This lug width is proportionally suited to the 44.70mm case diameter and represents the standard specification for mid-range sports chronographs. To measure accurately, calculate the distance between the lug centres perpendicular to the 12-6 case line.

Selection depends on intended use and aesthetic preference. An alligator strap with vegetable tanning combines artisanal refinement with sports functionality. For absolute practicality, NATO or vulcanised rubber ensures waterproofing and maintenance-free wear. Aged calf leather strikes an ideal compromise between sophisticated appearance and longevity.

The lugs are equipped with spring bars. Use a dedicated lug removal tool—available from any professional watchmaker—to gently compress the spring and slide the strap from its housing. The operation requires only seconds once you become familiar with the motion.

Yes, any artisanal strap manufactured to 22mm lug width specification is compatible with your watch. Verify that the strap features properly fitted standard spring bars and that its ends fit the lugs without excessive play. Milano Straps offers a curated selection of straps certified for this dimension.

Durability depends on tanning quality and intensity of wear. An alligatore strap with vegetable tanning lasts 3–5 years under daily use with proper care. High-grade calf achieves 4–6 years with appropriate maintenance (protection from excess water, periodic cleaning, air drying). Rubber and NATO offer near-indefinite service life, susceptible only to superficial aesthetic wear.
