FAQ
What is the exact lug width of the L & Jr Step One S1501?
The lug width of the L & Jr Step One S1501 is 20mm. This parameter is essential for selecting the correct aftermarket strap: it represents the distance between the lugs that connect the strap to the case. At this width, Milano Straps offers a complete selection of handcrafted leather, fabric and rubber straps.
What is the best strap for the L & Jr Step One S1501?
The best strap depends on your usage and personal aesthetics. For formal wear, we recommend alligator or calf leather with vegetable tanning; for daily versatility, a NATO or technical rubber strap. The 45mm stainless steel case allows both elegant and sporty interpretations, provided the strap is made with artisanal quality materials.
How do I change the strap on my S1501?
The strap on the L & Jr Step One S1501 is replaced using a spring bar tool (the pins that connect the strap to the lugs). Remove the original strap by gently pushing the pins towards the centre, then insert the new strap by aligning the holes with the pins and let them snap into position. If you are inexperienced, Casati Milano offers this service by appointment with free aesthetic consultation.
Can I use an aftermarket 20mm strap on this watch?
Yes, absolutely. Any strap with 20mm lugs is compatible with the L & Jr Step One S1501. Milano Straps offers a wide range of artisanal straps in 20mm, from full grain leather to technical models in rubber and fabric, all made with attention to construction details and finishes.
How long does a leather strap last on the L & Jr Step One S1501?
The lifespan of a leather strap depends on usage, climate and material: a strap in alligator or shell cordovan with artisanal vegetable tanning lasts an average of 3-5 years with daily use, developing a natural patina that characterises time. A finer calf requires more care but offers superior comfort. Milano Straps recommends rotating straps to distribute wear and performing periodic cleaning with specific products.
