Strap for Altitude Premiere Small Seconds

The lug width of the Altitude Premiere 101PEJT is precisely 20mm. This measurement was deliberately calibrated by Alexandre Meerson to maintain ideal proportions between the 41mm case diameter and overall visual mass. To verify compatibility, measure the space between the two lugs at the bottom of the case: it must be exactly 20mm.

For the 101PEJT, we recommend straps in alligator leather with vegetable tanning (to enhance the purity of the titanium case) or rigid calf with natural grain. If you seek daily versatility, a NATO or high-quality FKM rubber offers practicality without aesthetic compromise. Your choice depends on intended use: formal elegance suggests leather, daily wear suggests NATO or rubber.

Remove the watch from your wrist. Place it on a soft, flat surface. Locate the two fixing pins (called "spring bars") that connect the strap to the lugs. Using an appropriate tool (spring bar tool), apply gentle pressure to the pin, compressing it slightly downward. The old strap will disengage. Insert the new strap by positioning the pins in the proper holes, ensuring the spring mechanism clicks into place. Verify the attachment is secure before wearing the watch.

Yes, any strap with a 20mm lug width is compatible with the 101PEJT. We recommend specialised strap manufacturers offering elevated quality control: investment in premium leather or materials is proportional to the sophistication of the watch. Always verify the actual lug width is 20mm prior to purchase.

A quality leather strap (alligator with vegetable tanning, Hermès calf) typically lasts 3–5 years of daily wear, with variation depending on exposure to moisture, perspiration, and frequency of use. Vegetable-tanned leather develops patina over time, improving aesthetically. Rubber or NATO straps last considerably longer (5–10 years) due to resistance to external factors. Proper maintenance (moisture protection, periodic cleaning) extends longevity.
