Strap for Classic Timepieces 1736 St I 4N

The Sinn Classic Timepieces 1736.011 features a lug width of 19mm. This dimension was selected to ensure optimal optical proportions relative to the 36mm case diameter. A compatible strap must measure precisely 19mm between the spring bar attachment points.

For this model, we recommend a vegetable-tanned alligator or calf leather strap, which develops a natural patina over time, harmonising with the ageing of the stainless steel case. Alternatively, a heavyweight cotton NATO offers aesthetic versatility, whilst natural vulcanised rubber represents the most contemporary choice for intensive wear.

Changing the strap on the Sinn 1736.011 requires a spring bar remover tool. Position the tool in the small lateral slot of each bar, press gently to release the internal spring, then extract the bar from its seat. Reverse the procedure to install the new 19mm strap, ensuring both bars click firmly into position.

Yes, provided the lug width is certified as 19mm. However, we recommend verifying that the strap was manufactured specifically for this width, as some manufacturers employ tolerances that may cause fitting issues. Bespoke artisanal straps guarantee absolute compatibility.

A high-quality vegetable-tanned alligator or calf strap typically lasts 5-8 years under moderate daily wear. Longevity depends on climate (humidity accelerates ageing), maintenance (periodic cleaning with a soft cloth extends service life), and frequency of use. Natural vulcanised rubber resists degradation for 7-10 years under normal conditions.
