Frequently asked questions

What is the lug width of the Longines PrimaLuna L8.110.5.78.2?

The Longines PrimaLuna L8.110.5.78.2 features a 6mm lug width, a specialised measurement common in compact ladies' watches (26.50mm case diameter). To verify compatibility, measure the horizontal distance between the case lugs: it must match exactly 6mm. Milano Straps offers a dedicated collection of 6mm straps for this model.

Which strap pairs best with the Longines PrimaLuna L8.110.5.78.2?

We recommend alligator leather in dark brown tones (cognac or chocolate) to amplify the warm-cool contrast between rose gold and stainless steel. Alternatively, vegetable-tanned black calf offers formal versatility, whilst dark blue alligator creates vintage sophistication. For daily wear, black fabric NATO provides practicality whilst maintaining elegance.

How do I change the strap on the Longines PrimaLuna L8.110.5.78.2?

Use a spring bar tool to gently extract the elastic pins from the lugs. The process requires precision due to the narrow 6mm lugs: position the tool under the pin from the case side, press lightly outward and slide the old strap away. Insert the new strap, aligning the holes and ensuring the spring bars click firmly into position. If uncertain, Casati Milano offers complimentary strap change service for straps purchased through us.

Are there aftermarket straps compatible with the 6mm lug width of the Longines PrimaLuna L8.110.5.78.2?

Yes. Milano Straps offers a specialised collection of aftermarket straps for 6mm lug width, compatible with the Longines PrimaLuna L8.110.5.78.2. Available in alligator, vegetable-tanned calf, NATO and FKM rubber, they are customisable in length, stitching thread and initials. Casati Milano atelier also creates bespoke made-to-measure straps with personal leather selection and 18-month warranty.

How long does a leather strap last on the Longines PrimaLuna L8.110.5.78.2?

Durability depends on material: quality alligator lasts 5–7 years with moderate daily wear; vegetable-tanned calf 4–6 years; shell cordovan 8–12 years due to natural density. Fabric NATO resists 3–5 years. Factors such as humidity, sun exposure and frequency of wear influence longevity. Milano Straps guarantees 18 months on Casati Milano bespoke straps, whilst standard straps maintain certified quality over time.
