Strap for Spirit 36

The lug width of the Longines Spirit L2.699.4.23.2 is exactly 18 millimetres. This dimension is critical for aftermarket strap compatibility. Measure the distance directly between the two lugs at the base of the case using a ruler.

There is no single optimal choice; it depends on intended use and aesthetic preference. For formal wear, we recommend alligator or shell cordovan in black. For daily versatility, a fabric NATO strap in blue or grey. For aeronautical heritage, structured rubber in black. All must feature an 18mm lug width for compatibility.

Strap replacement requires a spring bar removal tool to release the two elastic pins at the lug ends. Position the tool in the groove on the pin's side, pressing downward gently to compress the spring. Remove the old strap and insert the new one, ensuring both elastic pins fully engage the lug attachments.

Yes, provided the lug width is precisely 18 millimetres. The milanostraps.it online catalogue offers options validated for compatibility with this case. Artisanal personalised straps significantly enhance the user experience compared to generic alternatives.

An artisanal strap crafted with vegetable tanning leather typically lasts between 2 and 4 years with daily wear. Longevity depends on ambient humidity, frequency of use, and maintenance practices. Rotating multiple straps on the same case significantly extends the lifespan of each.
