Strap for Sideral Forged Carbon / Yellow

The lug width is 20mm, measured between the pins or housing slots that secure the strap to the case. This dimension is critical to verify before purchasing an aftermarket strap, as 20mm is not the universal standard across all 41mm cases.

For this forged carbon case, we recommend high-quality alligator leather or vegetable-tanned calf in dark tones (black, dark brown, slate grey). Black alligator amplifies formal elegance, whilst calf develops a natural patina over time. For casual wear, a Ballistic nylon NATO or FKM rubber strap maintains technical coherence with the timepiece's philosophy.

The Sideral T145.407.97.057.00 features an integrated lug (non-removable). Strap replacement requires a specialised tool (spring bar extractor) to carefully remove the pins anchoring the strap to the case. We recommend entrusting this operation to a professional to avoid damage to the forged carbon case or pins.

Yes, provided the strap is specifically dimensioned for the 20mm lug width. Always verify the technical specifications of the strap before purchase. A superior quality strap can significantly elevate the timepiece's aesthetics, provided it is crafted with attention to proportions and finishing.

A quality leather strap, subject to regular maintenance (gentle cleaning, avoiding immersion), lasts approximately 3–5 years with daily wear. Vegetable-tanned leather ages naturally and may endure longer, developing a fascinating patina. Durability depends on exposure to perspiration, humidity, and daily activity type. FKM rubber, by comparison, resists atmospheric agents more robustly, though less refined aesthetically.
