Sinn
Classic Timepieces 2300.010— lug 20mm

The lug width of the Sinn 2300.010 is 20 millimetres. This specification is critical for strap compatibility. To verify it precisely, measure the space between the horizontal lugs using a digital calliper positioned perpendicular to the case.

Alligator leather in brown or black tones pairs splendidly with yellow gold. Alternatively, vegetable-tanned calf in cognac develops an amber patina over time. For those valuing rare materials, burgundy shell cordovan represents the premium choice.

Remove the watch from your wrist. Locate the horizontal lugs at the 12 and 6 o'clock positions. Using a spring bar tool or similar instrument, push the pins downward to extract the old strap. Align the new strap's holes with the pins and reinsert them securely.

Yes, any strap with a 20mm lug width is compatible. Artisanal Milan-made straps are specifically engineered to these specifications and offer superior construction quality and longevity compared to generic alternatives.

A quality leather strap, subjected to moderate use (5–6 days weekly), typically lasts 3–5 years. Vegetable-tanned leather ages gracefully, developing an appealing patina. Shell cordovan and alligator, owing to fibre density, can exceed 7–8 years with proper maintenance including periodic cleaning and air drying.
