Strap for Armand Nicolet M02 Day Date

The lug width of the 9740A-AG-P974MR2 is 22mm. This measurement is precise and not interchangeable with standardised lugs of 20mm or 24mm. To verify correctly, measure from the base of the case to the top of the opposite lug, in a straight line. Ensure that the strap passant slides without friction within the lug.

For the M02, we recommend alligator leather or vegetable-tanned calf, which balance the sports character of the stainless steel case with constructive refinement. Alligator with regular grain dialogues beautifully with the satin-finished steel surface. If versatility is required, textile NATO or FKM rubber ensures practicality without compromising the model's sporty character.

To change the strap, locate the suspension pins (spring bars) at the lug ends. Use a dedicated tool—gentle pressure or a spring bar tool—to push the pin towards the case centre, creating space to remove the old strap. Insert the new strap by aligning the holes with the pins and release carefully. Verify that the passant slides without resistance and that there is no slippage.

Yes, 22mm artisanal straps are fully compatible. Before purchase, verify that the passants and buckle are internally proportioned to your daily use. The constructive variability of artisanal straps reflects the uniqueness of each piece: consult the vendor for details on internal width, thickness, and tolerances.

A natural leather strap, subject to regular moderate use, typically lasts 3–5 years. Durability depends on tanning (vegetable vs. synthetic), stitch quality, and change frequency—rotating straps weekly allows the leather to rest and age more slowly. Direct sunlight and humidity exposure accelerate ageing. A vegetable-tanned calf strap develops noble patina over time, whilst alligator, due to its lower pore density, tends to last slightly longer.
