Strap for The Lindbergh Hour Angle Watch

The lug width of the Longines Heritage L2.678.4.11.0 is 25mm. This is a non-standard measurement, larger than most commercially available watch straps. To verify conformity, measure the internal space between the two lugs with a digital calliper, or contact your authorised dealer for precise confirmation.

Given the aviator character of this model, we recommend a deep brown or cognac alligator strap with fine grain. Alternatively, a vegetable-tanned calf leather in brown or chocolate offers natural ageing and tactile sensitivity. For aquatic sports, a vulcanised rubber strap provides durability and grip. A black ballistic NATO canvas strap suits daily wear perfectly.

Use a spring bar tool to compress the elastic pins at the ends of the current strap. Once removed, align the pins of the new 25mm strap with the holes in the lugs and allow the pins to snap into position. Verify the strap is securely fastened by gently tugging. If unsure, consult a professional watchmaker.

Yes. All straps with a 25mm lug width are compatible with the L2.678.4.11.0, regardless of manufacturer. Ensure the pins are standard (1.5mm or 1.8mm diameter) and the strap length is appropriate for your wrist. Milano Straps offers 25mm straps customisable in leather, colour, and length.

A high-quality artisanal alligator or calf strap typically lasts 3–5 years with regular daily wear, thanks to the material's inherent durability. Longevity depends on wear frequency, ambient humidity, sun exposure, and maintenance. A vulcanised rubber strap resists 5–7 years. Milano Straps straps include an 18-month warranty.
