The Heritage

The Lundis Bleus 1100-03 is a 40mm stainless steel watch from the contemporary Swiss watchmaking tradition. It features a Miyota 9015 quartz movement with hours, minutes, seconds and date display, paired with a satin-finished steel case that develops a patina over time. The 19mm lug width is a specific construction requirement that demands proper sizing for strap compatibility and visual balance with the case.

FAQ

What is the lug width of the Lundis Bleus 1100-03?

The Lundis Bleus 1100-03 features a 19-millimetre lug width. This specific dimension is not standard in industrial mass-market production, making it essential to source bespoke, artisanal straps. Measurement is conducted by positioning a digital calliper perpendicularly between the inner points of both lugs, with the watch lying flat on a stable surface.

What is the best strap for the Lundis Bleus 1100-03?

No single solution exists; rather, the optimal choice reflects your lifestyle and aesthetic. Alligator represents formal elegance; vegetable-tanned calf offers daily versatility and developing patina; NATO fabrics deliver practicality and interchangeability; rubber provides maximum sports functionality. Selection depends on your primary context of use.

How do you change the strap on a Lundis Bleus 1100-03?

Strap replacement requires a specialised tool called a spring bar tool, or alternatively a fine-pointed toothpick. Position the watch on a soft surface, locate the small hole on the lug flank, insert the tool to compress the lug spring, and extract the old strap terminus. Insert the new strap's lug into the same slot and allow the spring to close securely.

Which aftermarket straps are compatible with the 1100-03?

Any strap featuring a 19-millimetre lug width is compatible with the 1100-03. At milanostraps.it you will discover a comprehensive selection of artisanal straps in this dimension: leather, alligator, shell cordovan, NATO, and vulcanised rubber. All straps feature stainless steel hardware compatible with your watch's case.

How long does a leather strap last on a watch like the 1100-03?

Leather strap longevity depends on treatment, usage frequency, and tanning quality. A vegetable-tanned calf strap, worn daily, typically endures 3 to 6 years before showing significant wear. Alligator, possessing naturally more robust skin, may last 5-7 years. Vulcanised rubber resists 10-15 years with proper maintenance. Constant exposure to moisture and heat accelerates ageing across all natural materials.
