Strap for Lundis Bleus Ref. 1100 Stainless Steel / Silver / Rose Index

The Lundis Bleus 1100-04 features a lug width of 19mm. This measurement represents the distance between the attachment points of the strap on the case and is essential for selecting compatible straps. Measuring lug width correctly involves positioning a calliper perpendicularly between the internal attachment points, excluding the case thickness. The 19mm specification on your model provides access to a diverse selection of artisanal straps without limiting your options to restricted catalogues.

The optimal strap choice depends on intended use context and personal aesthetic preference. For formal elegance and evolving patina, alligator with vegetable tanning in cognac or dark brown tones is ideal. For daily versatility, vegetable-tanned calf in navy blue or taupe offers softness and seasonal adaptability. For practicality, a NATO strap in grey anthracite technical fabric maintains case visibility and functionality without compromise. Vulcanised rubber represents the choice for sports contexts and humid environments. We recommend selecting material based on the context where your watch will see most frequent use.

Strap replacement on the 1100-04 is accomplished via the case lugs. Obtain a spring bar tool or consult a qualified watchmaker. Insert the tool gently into the lug aperture to compress the internal spring, lift the old strap and remove it entirely. Repeat on the opposite lug. To install the new 19mm strap, insert the first attachment by again compressing the spring, secure the lug, then repeat on the other side. A straightforward operation requiring only attention and precision to avoid case scratching.

Absolutely. The Lundis Bleus 1100-04 with 19mm lug width is fully compatible with quality aftermarket straps. An artisanal strap in alligator, calf, shell cordovan or technical fabric ensures aesthetic flexibility without constructive compromise. The critical factor is verifying that your chosen strap is genuinely manufactured for 19mm lug width—always check technical specifications before ordering. High-quality artisanal straps frequently offer superior longevity compared to original equipment alternatives and develop unique patina over time, reflecting the character your watch deserves.

Leather strap longevity depends on construction quality, material specification and usage patterns. A quality chrome-tanned calf strap typically resists daily use for 3–5 years before requiring replacement, maintaining acceptable appearance throughout this period. Alligator with vegetable tanning, if properly maintained (avoiding prolonged immersion and sustaining hydration with specialist products), extends to 5–7 years or beyond, developing fascinating patina. Shell cordovan, owing to material density, can achieve 8–10 years of functional life. Vulcanised rubber maintains elasticity for 4–6 years before stiffening. We recommend protecting your strap from excessive moisture and periodically rotating alternatives across seasons to extend longevity.
