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

The lug width of the Lundis Bleus 1100-05 is 19 mm. This measurement, uncommon compared to standard sizes (18, 20, 22 mm), makes the model distinctive and requires precise sourcing of compatible straps. Correct measurement is performed by placing a calliper on the internal distance between the two horizontal attachment bars.

The best strap depends on usage and personal preference. For maximum elegance, alligator with vegetable tanning in cognac or dark brown offers natural patina and durability. For daily versatility, smooth black calfskin provides aesthetic confidence. For informal or sports contexts, a high-quality cotton-nylon NATO preserves the watch's character without sacrificing practicality. In all cases, a stainless steel deployant clasp is recommended.

To change the strap, remove the lug bars (the two horizontal pins) using a dedicated tool (spring bar tool) or a small lever. Insert the sharp tip of the tool into the small lateral holes of each bar and lift gently to disengage. Once removed, the strap separates from the case. Proceed in reverse to install the new 19 mm strap, ensuring both bars are correctly anchored in each lug.

Any strap with a 19 mm lug width is compatible with the 1100-05. Compatibility depends solely on the internal width between the lugs, not on the watch brand. On milanostraps.it, a wide selection of 19 mm straps is available in alligator, calfskin, shell cordovan, NATO and rubber, all handcrafted and ready for shipping.

The durability of a leather strap depends on material quality and maintenance. High-quality vegetable-tanned alligator, worn daily under normal conditions, maintains structural integrity for 5-7 years. Calfskin, less resistant to abrasion, has an average lifespan of 3-5 years. Repeated exposure to moisture, direct heat or intense perspiration reduces these timeframes. Regular cleaning and storage in a dry environment significantly extend longevity.
