Strap for Classic Timepieces 1736 Classic

The lug width of the Sinn 1736.010 is 19 millimetres. This dimension is model-specific and requires custom-made straps to ensure precise fit with the case lugs. Measure lug width accurately by removing the existing strap and calculating the distance between the internal metal attachments.

For the Sinn 1736.010, we recommend vegetable-tanned alligator straps for formal and sophisticated use, chromium or vegetable-tanned calf leather for everyday versatility, or cotton or canvas NATO straps for sporty application. Choice depends on intended use and personal aesthetic preferences. Alligator offers superior elegance and durability over time.

To change the strap on the Sinn 1736.010, use a spring bar tool to depress the spring pins that secure the strap to the case lugs. Insert the tool tip under the pin protrusion and apply gentle downward pressure until the strap releases. Repeat for both ends. To install a new 19 mm strap, align the holes with the lugs and insert the pins under pressure until the locking click occurs.

Yes, the Sinn 1736.010 is fully compatible with artisanal aftermarket straps provided they are constructed to the 19 mm lug width specification. Always verify the technical specifications before purchase, confirming that the lug width matches and the attachment system is compatible with standard spring bars on the case.

Strap longevity depends on material quality, frequency of use, and maintenance care. A high-quality artisanal alligator strap with vegetable tanning typically lasts 5 to 10 years with moderate wear. A chromium-tanned calf strap has shorter durability, approximately 3 to 5 years. Continuous exposure to perspiration, water, and sunlight accelerates ageing. We recommend rotating between straps to extend longevity.
