Trésor 428.57.26.60.04.001— lug 13mm

The lug width of the Omega Trésor 428.57.26.60.04.001 is 13 millimetres. This measurement is specific to the model and calibrated to ensure harmonious proportions on the 26mm case. Always verify that any aftermarket strap complies with this exact measurement to avoid lateral play.

For the Trésor 428.57.26.60.04.001 we recommend alligator in dark shades (black, brown, blue) that create elegant contrast with the Moonshine Gold. Alternatively, vegetable-tanned calf offers comfort and develops a natural patina that ages beautifully. For versatility, silk NATO straps provide practicality without aesthetic compromise.

The Trésor uses standard spring bars. With a dedicated tool or precision instrument, gently push the spring toward the inside to release the lug from the case slot. Remove the old strap and insert the new one ensuring the spring clicks correctly into position. If you are not experienced, contact the Casati Milano atelier for professional strap change.

Durability depends on usage and maintenance. A quality alligator or calf offers 3-5 years of regular use before requiring replacement. Shell cordovan is even more durable (5-7 years). Vegetable-tanned leather develops a natural patina over time, increasing aesthetic appeal. Keep the strap dry and away from heat sources to maximise its lifespan.
