Strap for Lady Serenade Stainless Steel / MOP - Index Line / Satin - Folding

The lug width is 18mm. This measurement corresponds to the distance between the two lugs on the case and is determined by the proportionate geometry of the model (36mm case diameter). Any replacement strap must have this exact width to mount correctly on the attachment pins.

For this Lady Serenade, we recommend alligator straps with vegetable tanning (cognac or burgundy) to maximise chromatic contrast with the stainless steel case. Alternatively, vegetable-tanned calf leather in matching tones for understated elegance, or a cotton-polyester NATO strap for daily versatility. Choice depends on usage context and undertone of wrist skin.

The Lady Serenade 1-39-22-12-02-04 strap is replaced by removing the attachment pins (spring bars) that connect the lugs to the strap passages. Using a spring bar tool or small cross-head screwdriver, gently push the pin outward until the old strap is freed. Insert the new strap, aligning the holes, and reinsert the pin. A procedure of just a few minutes without risk to the case.

Yes. Any strap with an 18mm lug width is compatible with the model 1-39-22-12-02-04. We recommend artisanal straps with sewn and leather-lined lugs, as they maintain rigidity and comfort over time. Verify that the strap passages have sufficient internal diameter to accommodate the case pins (typically 1.2–1.5mm).

A natural leather strap with vegetable tanning lasts 3–5 years with moderate daily wear (5–7 days weekly), depending on ambient humidity and cleaning frequency. Alligator or shell cordovan straps typically last 6–8 years. The natural patina that forms is not deterioration but acquired character. Periodic maintenance (hydration with natural balms) extends longevity.
