Frequently asked questions

What is the lug width of the Longines Flagship L4.274.3.07.7?

The lug width of the Longines Flagship L4.274.3.07.7 is 13 millimetres. This dimension is specific to the women's Flagship collection and is compatible with bespoke straps manufactured to this specification. To verify, measure the internal space between the two lugs using a digital calliper or ruler.

Which strap is most suitable for the Longines Flagship L4.274.3.07.7?

For the Flagship L4.274.3.07.7, we recommend straps in warm brown alligator or vegetable-tanned calf leather, which reflect the sobriety of the stainless steel case. For informal wear, a NATO strap in grey or navy blue maintains versatility. Choice depends on usage context and personal preferences for patina development.

How do you change the strap on the Longines Flagship L4.274.3.07.7?

The strap is changed by removing the spring bars that connect the strap to the lugs. Use a dedicated pin pusher tool to push the bar toward the centre, release the old strap, and insert the new one by sliding the bars into the appropriate holes. Never force to avoid case damage. If inexperienced, consult a professional watchmaker.
