Strap for S.A.R. Rescue Timer Black / Strap

The lug width is precisely 20mm. This dimension is specific to this model and is determined by the compact geometry of the 42mm case. Measurement is performed using a digital calliper at the midpoint between the upper and lower lugs, with a tolerance of ±0.1mm to ensure perfect compatibility with artisanal straps.

The choice depends on intended use. For rescue operations and humid environments, vulcanised rubber ensures maximum grip and resistance. For formal contexts, shell cordovan with vegetable tanning evolves over time and offers elegance without compromise. A NATO strap in Cordura represents the balance between outdoor durability and versatility, whilst thick black calf leather expresses the German rigour characteristic of the model.

Strap replacement is achieved by removing the attachment bars (spring bars) that secure the strap to the case lugs. Using a spring bar tool (or a small flat screwdriver), insert the lever into the recess on the side of the case, release the spring pressure and extract the attachment bar. Repeat on the opposite side. To install the new strap, align it with the lugs and reinsert the attachment bars, ensuring the spring lock engages on both sides.

Yes, absolutely. The M1-41-03-KB is compatible with any strap in 20mm lug width, provided it is constructed to artisanal standards and with precise manufacturing tolerances. The artisanal leather, NATO and rubber straps available on MilanoStraps are selected for perfect adherence to the lugs and aesthetic coherence with the constructive spirit of the model.

A quality leather strap (thick calf or shell cordovan with vegetable tanning) lasts 3-5 years with daily wear, provided regular maintenance is performed. Excessive moisture and direct sun exposure accelerate ageing. To extend the lifespan, apply vegetable tanning balm every 6-8 months and remove the strap for one day per month to allow drying. A NATO or rubber strap has indefinite lifespan if cleaned regularly with fresh water.
