Frequently asked questions
What is the lug width of the Longines PrimaLuna L8.111.9.83.6?
The lug width of the Longines PrimaLuna L8.111.9.83.6 is 6 millimetres. This measurement represents the internal distance between the case lugs and is essential for identifying compatible straps. It is a non-standard dimension in the watch market, so it is crucial to verify this specification before purchasing an aftermarket strap. You can measure the lug width using a digital calliper, positioning it perpendicularly to the fixing pins.
What is the best strap for a Longines PrimaLuna L8.111.9.83.6 in rose gold?
For a rose gold PrimaLuna, black alligator remains the most refined and versatile choice: the chromatic contrast emphasizes the elegance of the precious case, ideal for formal occasions. If you prefer aesthetic continuity, vegetable-tanned calf leather in hazelnut or dark brown tones develops a warm patina over time that dialogues naturally with rose gold. For those seeking character and durability, shell cordovan in its natural red tone creates a masterful combination. In the sporty-casual realm, a cotton NATO or perforated rubber strap in pearl grey maintains stylistic equilibrium without functional compromises.
How do I change the strap on a Longines PrimaLuna L8.111.9.83.6?
Strap replacement is accomplished by removing the fixing pins. Use a spring bar removal tool to depress the elastic pin from one end, freeing the lug from the case. Repeat the operation on the other side. Insert the new strap by aligning the lug with the case hole and, whilst keeping the pin slightly depressed, snap the opposite end until it clicks into place. Verify that both sides are perfectly seated before wearing the watch. If you are inexperienced, the Casati Milano atelier performs this operation with precision and security checks.
Is the Longines PrimaLuna L8.111.9.83.6 compatible with aftermarket straps?
Yes, the PrimaLuna L8.111.9.83.6 is compatible with aftermarket straps provided they respect the 6-millimetre lug width. The actual strap width can vary (from 14 to 20mm, depending on aesthetic preference), but the lug must correspond to the case's 6mm dimension. Milano Straps offers a selection of 6mm straps in various materials—alligator, calf, shell cordovan, NATO, rubber—all customisable in length, initials, and stitching colour. The Casati Milano atelier also creates fully bespoke straps with personal leather selection.
How long does a leather strap last on a daily-worn Longines?
A quality artisanal leather strap, such as those created by Milano Straps or in-house, has an average lifespan of 3–5 years with daily use and proper care. Alligator and shell cordovan, by their nature, are more durable (up to 7–8 years); calf requires more frequent maintenance but remains elegant for 4–6 years. Natural ageing of leather entails progressive visual change (patina development), not necessarily a loss of structural integrity. Remove the strap during showers and baths, clean periodically with a dedicated leather cleanser (oil or neutral cream), and store away from direct heat sources. Casati Milano's 18-month warranty covers manufacturing defects and material faults; natural wear is part of the conscious ageing of the object.
