The Heritage

The Lundis Bleus 1100 model (Ref. 1100-01) is a 40mm stainless steel watch featuring a Miyota caliber 9015 movement with hours, minutes, seconds and date display. It has a 19mm lug width, creating balanced proportions between the case diameter and strap contact surfaces. The satinized stainless steel case is corrosion-resistant and develops natural patina over time, while the sapphire crystal protects the dial. This Swiss-inspired tool watch emphasizes functional clarity without excess ornamentation, with the 19mm lug width representing a refined compromise for a defined wrist instrument.

FAQ

What is the exact lug width of the Lundis Bleus 1100 1100-01?

The lug width of the Lundis Bleus 1100 1100-01 is 19mm. This measurement represents the distance between the inner shoulders of both lugs and determines strap compatibility. At 19mm, this is a niche dimension, less common than 20mm or 22mm specifications, yet proportionally perfect for the 40mm case diameter.

What type of strap is recommended for the Lundis Bleus 1100 1100-01?

For the Lundis Bleus 1100 1100-01, alligator straps with vegetable tanning are strongly recommended, as they enhance the design's inherent sobriety. Heavy cotton NATO straps represent an excellent alternative for those seeking tactical versatility and tactile feedback. FKM rubber is ideal for humid environments or sports activities. Your choice should align with intended usage and desired aesthetic character.

How do you change the strap on the Lundis Bleus 1100 1100-01?

Strap replacement requires a spring bar tool to compress the internal springs within the lugs. Compress the spring bar, and the existing strap separates cleanly from both lugs. Insert the new strap's bars into the lug holes and press until the springs lock into place with an audible click. Reinstallation is the inverse procedure. No specialised technical skills are required.

Are quality aftermarket straps available for the 1100-01 model?

Yes, Milano Straps curates an extensive collection of 19mm artisanal straps: alligatore, shell cordovan, vegetable-tanned calf leather, and FKM rubber. Each strap is tested for precise fitment with the 1100-01's 19mm lugs. All straps ship ready-to-wear with personalisation options: buckle type (deployante clasp or standard), colour finishes, and edge treatments reflect individual preferences.

How long does a leather strap last on the Lundis Bleus 1100 1100-01?

Longevity depends on usage patterns and material specification. An artisanal alligatore or calf strap, with appropriate maintenance (avoiding prolonged water exposure, periodic soft-cloth cleaning), typically delivers 3–5 years of daily wear before natural aging occurs. Leather develops character through patina and micro-scratching. Accelerated deterioration results from chronic humidity or chlorinated water exposure.
